Subject: 17) Can I save the state of my X session, like toolplaces does?
|
|
|
|
Although no known window manager directly supports such a feature
|
|
(olvwm and swm may come close) -- which may be equivalent to writing out a
|
|
.xinitrc or .xsession file naming the geometry and WM_COMMAND of each
|
|
application -- there is a contributed application which does much of what
|
|
you are looking for, although it is not as complete as the SunView program
|
|
toolplaces. Look for the application "xplaces" on an archive-server near
|
|
you. There are several versions of this program floating around; look for a
|
|
recent vintage. [10/90]
|
|
Some new pseudo session-managers such as HP's vuewm provide for the
|
|
saving of sessions including information on the geometry of currently-running
|
|
applications and the resource database. [Bjxrn Stabell
|
|
(bjoerns@staff.cs.uit.no); 3/93.]
|
|
|
|
In Release 6 a new session management protocol was defined, called
|
|
XSMP (see doc/specs/SM), for telling applications when to save their internal
|
|
state and for managing user dialog during the save. R6 contains a very
|
|
simple session manager that exercises this protocol in the workInProgress
|
|
directory; look for xsm. R6 also added a new shell widget class to Xt to
|
|
make it easier to write applications that react to messages from a session
|
|
manager. The window managers still have to do the work to save the window
|
|
positions. [Dave Wiggins (dpw@x.org); 5/94.]

|
|
Subject: 18) How do I use another window manager with DEC's session manager?
|
|
|
|
DEC's session manager will start dxwm up by default. To override this,
|
|
add to your .Xdefaults file something like this line, naming the full pathname:
|
|
sm.windowManagerName: /wherever/usr/bin/X11/your_favorite_wm
|
|
|
|
----------------------------------------------------------------------
|
|
Subject: 19) How do I change the keyboard auto-repeat rate?
|
|
|
|
You can turn auto-repeat on or off by using "xset r on|off".
|
|
|
|
The base X11 protocol, doesn't provide for varying the auto-repeat
|
|
rate, which is a capability not supported by all systems.
|
|
Some pre-R6 servers may provide command-line flags to set the rate at
|
|
start-up time. If you have control over server start-up (see the man pages
|
|
for xinit and xdm), you can invoke the server with the chosen settings; for
|
|
example, you can start the R5 Xsun sample server with the options "-ar1 350
|
|
-ar2 30" to reduce the sensitivity of the keyboard.
|
|
|
|
The R6 X Keyboard Extension provides a vendor-independent way to
|
|
control repeat delay and rate.
|
|
|
|
----------------------------------------------------------------------
|
|
Subject: 20) How do I remap the keys on my keyboard to produce a string?
|
|
|
|
There is no method of arranging for a particular string to be produced
|
|
when you press a particular key. The xmodmap client, which is useful for
|
|
moving your CTRL and ESC keys to useful places, just rearranges keys and does
|
|
not do "macro expansion."
|
|
Some (few) clients, including xterm and several X-based editors,
|
|
accept a translation resource such as:
|
|
xterm*VT100.Translations: #override \
|
|
<Key>F1: string("setenv DISPLAY unix:0")
|
|
which permits the shorthand F1 to be pressed to reset the display locally
|
|
within an xterm; it takes effect for new xterm clients. To include control
|
|
characters in the string, use \nnn, where nnn is the octal encoding of the
|
|
control character you want to include.
|
|
Window managers, which could provide this facility, do not yet; nor
|
|
has a special "remapper" client been made available.
|
|
|
|
----------------------------------------------------------------------
|
|
Subject: 21) How do I make a screendump or print my application (including menus)?
|
|
|
|
The xwd client in the X11 distributions can be used to select a window or the
|
|
background. It produces an XWD-format file of the image of that window. The
|
|
file can be post-processed into something useful or printed with the xpr
|
|
client and your local printing mechanism. To print a screendump including a
|
|
menu or other object which has grabbed the pointer, you can use this
|
|
command:
|
|
|
|
csh% sleep 10; xwd -root > output.xwd &
|
|
|
|
and then spend 10 seconds or so setting up your screen; the entire current
|
|
display will be saved into the file output.xwd. Note that xwd also has an
|
|
undocumented (before R5) -id flag for specifying the window id on the
|
|
command-line. [There are also unofficial patches on ftp.x.org to xwd for
|
|
specifying the delay and the portion of the screen to capture.]
|
|
|
|
Two publicly-available programs which allow interactive definition of
|
|
arbitrary portions of the display and built-in delays are xsnap and xgrabsc.
|
|
|
|
xgrabsc is a free screendump program that provides multiple selection styles
|
|
and several output formats. Selection styles include xwd-style point and
|
|
click, dragging a rectangle over an arbitrary portion of the screen, timed
|
|
snapshots for menu capturing, and keyboard-based selection. Output formats
|
|
are xwd, XPM (v1 and 2), bitmap, puzzle, and monochrome, greyscale, and color
|
|
PostScript. PostScript output can be in ready-to-print true-scale form or
|
|
encapsulated for inclusion in Frame, xfig, and other programs that accept EPS
|
|
graphics. There are several versions of xgrabsc; version 2.3, available on
|
|
ftp.x.org [9/93] is the most recent. xgrab, part of the package, is an
|
|
interactive front-end to xgrabsc.
|
|
|
|
xwpick (formerly xpick) (by Evgeni Chernyaev (chernaev@mx.ihep.su)) is
|
|
available on ftp.x.org as xwpick-2.20.tar.Z; it creates Level 2 color
|
|
PostScript dumps of X screens and can generate GIF, PICT, and other formats.
|
|
PostScript output is very small. xwpick runs under VMS and Unix systems.
|
|
|
|
xsnap includes some asnap features and supersedes it; it also renders XPM
|
|
output [version unknown]. It is available on ftp.x.org or avahi.inria.fr; see
|
|
xsnap-pl2.tar.Z.
|
|
|
|
A screen-dump and merge/edit program combining features of xwd and xpr is
|
|
available from vernam.cs.uwm.edu as xdump1.0.tar.Z. Information:
|
|
soft-eng@cs.uwm.edu.
|
|
|
|
xprint, by Alberto Accomazzi (alberto@cfa.harvard.edu) is available from
|
|
cfa0.harvard.edu (128.103.40.1) as /pub/wipl/xprint.export-2.1.tar.Z. The
|
|
package allows users to create encapsulated color PostScript files which will
|
|
print on any PostScript Level-1 compliant printer (black and white or
|
|
color).
|
|
|
|
To post-process the xwd output of some of these tools, you can use xpr, which
|
|
is part of the X11 distribution (moved to contrib in R6). Also on several
|
|
archives are xwd2ps and "import" (formerly XtoPS), which produce Encapsulated
|
|
PostScript with trimmings suitable for use in presentations (see
|
|
ftp.x.org:contrib/xwd2ps.tar.Z and
|
|
contrib/applications/ImageMagick/ImageMagick3.4.tar.Z). Also useful is the
|
|
PBMPLUS/Netpbm package on many archive servers; and the Xim package contains
|
|
Level 2 color PostScript output.
|
|
|
|
The xv program can grab a portion of the X display, manipulate it, and save
|
|
it in one of the available formats. ImageMagick has similar capabilities.
|
|
|
|
Also:
|
|
|
|
Bristol Technology (info@bristol.com, 203-438-6969) offers Xprinter, an Xlib
|
|
API for PostScript and PCL printers; a demo is in
|
|
ftp.bristol.com:/pub/Demos/DE.
|
|
|
|
ColorSoft 9619-459-8500) offers OPENprint; the package includes a
|
|
screen-capture facility, image-processing, and support for PostScript and
|
|
non-PostScript printers.
|
|
|
|
Some vendors' implementations of X (e.g. DECWindows and OpenWindows) include
|
|
session managers or other desktop programs which include "print portion of
|
|
screen" or "take a snapshot" options. Some platforms also have tools which
|
|
can be used to grab the frame-buffer directly; the Sun systems, for example,
|
|
have a 'screendump' program which produces a Sun raster file. Some X
|
|
terminals have local screen-dump utilities to write PostScript to a local
|
|
serial printer.
|
|
|
|
Some vendors' implementations of lpr (e.g. Sony) include direct support for
|
|
printing xwd files, but you'll typically need some other package to massage
|
|
the output into a useful format which you can get to the printer.
|

|
|
Subject: 22) How do I make a color PostScript screendump of the X display?
|
|
|
|
If you need color PostScript in particular, you can
|
|
|
|
- grab the screen-image using a program which can produce color
|
|
PostScript, such as xgrabsc, xprint, xwpick, and xv
|
|
|
|
- grab the screen-image using xwd and post-process xwd into color PS.
|
|
|
|
You can do this using xwd2ps or the "import" (formerly XtoPS) program from
|
|
the ImageMagick distribution. The PBMPLUS/Netpbm package is also good for
|
|
this, as is the Xim package.
|
|
|
|
Also:
|
|
|
|
Another alternative is to use the Xprinter product from Bristol Technology,
|
|
Inc. which provides PostScript output using the Xlib API. Send email to
|
|
info@bristol.com for details.
|
|
|
|
----------------------------------------------------------------------
|
|
Subject: 23) How do I make a screendump including the X cursor?
|
|
|
|
This can't be done unless the X server has been extended. Consider instead a
|
|
system-dependent mechanism for, e.g., capturing the frame-buffer.
|
|
|

|
|
Subject: 24) How do I convert or view Mac/TIFF/GIF/Sun/PICT/img/FAX images in X?
|
|
|
|
The likeliest program is an incarnation of Jef Poskanzer's useful++ Portable
|
|
Bitmap Toolkit, which includes a number of programs for converting among
|
|
various image formats. It includes support for many types of bitmaps,
|
|
gray-scale images, and full-color images. PBMPLUS has been updated recently;
|
|
the most recent version [12/91] is on ftp.x.org in
|
|
contrib/pbmplus10dec91.tar.Z.
|
|
|
|
Netpbm is based on the PBMPLUS 10dec91 release, with many additions and
|
|
improvements. It is intended to be portable to many platforms while allowing
|
|
for conversion of images between a variety of formats. The latest sources are
|
|
on several sites, including wuarchive.wustl.edu (128.252.135.4) and
|
|
peipa.essex.ac.uk (155.245.115.161). Contact oliver@fysik4.kth.se to be added
|
|
to the netpbm mailing list.
|
|
|
|
Another tool is San Diego Supercomputing Center's IMtools ('imconv' in
|
|
particular), which packages the functionality of PBM into a single binary.
|
|
It's available anonymous ftp from sdsc.edu (132.249.20.22).
|
|
|
|
Useful for viewing and converting some image-formats is Jim Frost's
|
|
xloadimage; the most recent [11/93] is on ftp.x.org in
|
|
contrib/xloadimage.4.1.tar.Z. Graeme Gill's updates to an earlier version of
|
|
xloadimage are also on ftp.x.org; see xli.README and xli.tar.Z.uu; version
|
|
1.15 was released 7/93.
|
|
|
|
xv (X Image Viewer), written by John Bradley (xv@devo.dccs.upenn.edu for XV
|
|
questions), can read and display pictures in Sun Raster, PGM, PBM, PPM, X11
|
|
bitmap, TIFF, GIF and JPEG. It can manipulate on the images: adjust, color,
|
|
intensity, contrast, aspect ratio, crop). It can save images in all of the
|
|
aforementioned formats plus PostScript. It can grab a portion of the X
|
|
display, manipulate on it, and save it in one of the available formats. The
|
|
program was updated 5/92; see the file contrib/xv-2.21.tar.Z on ftp.x.org.
|
|
Version 3.10a [3/95] is distributed as shareware. New versions are on
|
|
ftp.cis.upenn.edu in pub/xv.

Xim, The X Image Manipulator, by Philip Thompson, does essential interactive
|
|
displaying, editing, filtering, and converting of images. There is a version
|
|
in the X11R4 contrib area; but a more recent version (using R4 and Motif 1.1)
|
|
is available from gis.mit.edu (18.80.1.118). Xim reads/writes gif, xwd, xbm,
|
|
tiff, rle, xim, (writes level 2 eps) and other formats and also has a library
|
|
and command-line utilities for building your own applications.

|
xtiff is a tool for viewing a TIFF file in an X window. It was written to
|
|
handle as many different kinds of TIFF files as possible while remaining
|
|
simple, portable and efficient. xtiff illustrates some common problems with
|
|
building pixmaps and using different visual classes. It is distributed as
|
|
part of Sam Leffler's libtiff package and it is also available on ftp.x.org
|
|
and comp.sources.x. [dbs@decwrl.dec.com,10/90] xtiff 2.0 was announced in
|
|
4/91; it includes Xlib and Xt versions.

Subject: 25) Where can I get an X-based 3-D object viewer?
|
|
|
|
xmgf by Paul Hoad (P.Hoad@ee.surrey.ac.uk) is an interactive tool for viewing
|
|
2D and 3D objects typically in gf/OFF/NFF/IGRIP/MINICAD/SLA/DXF format
|
|
Sources are on ftp.x.org. Version 1.9.1 became available 12/93.
|
|
|
|
x3d is a V.Fast 3D Object viewer for X it needs no special hardware or or
|
|
widget libraries other that X and is optimized for speed.
|
|
|

XGobi can be used to to view such data.
|
|
|
|
VOGLE can be used to to view such data.

|
Subject: 26) How can I change the titlebar of my terminal window?
|
|
|
|
The solution involves sending an escape sequence to xterm which will cause it
|
|
to update the property which the window manager relies upon for the string
|
|
which appears in the window titlebar.
|
|
|
|
A solution is as easy as typing this in an xterm running a shell:
|
|
|
|
echo "ESC]2;TEXT^G"
|
|
|
|
where ESC is the escape key, TEXT is the string you wish to have displayed,
|
|
and ^G is a Control-G (the BEL character). Note that the semi-colon is
|
|
demanded by more recent versions of xterm. (Some shells and editors need an
|
|
escape character, typically ^V, before accepting control characters
|
|
literally.)
|
|
|
|
Here is a more complicated csh alias which changes the titlebar to the
|
|
current working directory when you change directories:
|
|
|
|
alias newcd 'cd \!*; echo -n ESC]2\;$cwd^G'
|
|
|
|
(for other shells e.g. ksh you will need to write a function for cd to print
|
|
this value).
|
|
|
|
The digit '2' in these strings indicates to xterm that it should change only
|
|
the title of the window; to change both the title and the name used in the
|
|
icon, use the digit '0' instead, and use '1' to change only the icon name.
|
|
|
|
Note: another way to do this, which prevents an incorrect display of the
|
|
local directory if a modified `cd` is used in a subshell, is to wrap the
|
|
escape sequences into the PS1 prompt itself.
|
|
|
|
If you are using DECterm, the sequence is "ESC]21;TEXTESC\". For an HPterm,
|
|
you need "ESC&f0k<length>DTEXT". Here <length> is the number of characters in
|
|
TEXT, as a decimal number in ASCII. To change the icon name, use
|
|
"ESC&f-1k<length>DTEXT". [thanks to Karsten Spang (krs@kampsax.dk); 12/94]

|
|
Subject: 27) Where can I find the xterm control sequences?
|
|
|
|
The best source of such information is in your R5/R6 sources in the file
|
|
ctlseqs.ms (R6: xc/doc/specs/xterm/ctlseqs.ms); a PostScript version is in
|
|
your R5 sources in mit/hardcopy/clients/ctlseqs.PS.Z and your R6 sources in
|
|
xc/doc/hardcopy/xterm/ctlseqs.PS.Z.
|
|
|
|
Both editions of O'Reilly's Volume 3, the X User's Guide, include an R5
|
|
version of the control sequences.
|
|
|
|
Other good sources of information include the R4 version of that document and
|
|
also the file in the R4 sources called mit/clients/xterm/ctlseq2.txt, a
|
|
compilation put together by Skip Montanaro (GE CR&D) listing the VT100
|
|
sequences. It dates from R3 but is fairly accurate. A hardcopy version was
|
|
published in the December 1989 XNextEvent (the XUG newsletter).
|
|
|
|
In a pinch, a VT100 manual will do.

Subject: 28) How can I use characters above ASCII 127 in xterm ?
|
|
|
|
In order to use special characters such as the o-umlaut, you need to
|
|
"stty pass8" (you may need "stty -parenb -istrip cs8" on strictly-POSIX
|
|
systems) but also to use a charcell ISO8859 font, such as
|
|
XTerm*font: -*-*-medium-r-normal-*-*-130-*-*-c-*-iso8859-1
|
|
XTerm*boldfont: -*-*-bold-r-normal-*-*-130-*-*-c-*-iso8859-1 [The
|
|
family is intentionally unspecified in this example.]
|
|
|
|
In addition, you may want to set this in your shell:
|
|
setenv LC_CTYPE iso_8859_1
|
|
|
|
For a given character above 127, you can determine the key to use with
|
|
the Alt modifier by finding the equivalent character below 127 (try using `man
|
|
ascii`). For example, o-umlaut (v) is Alt-v and the section character (') is
|
|
Alt-'.

Subject: 29) Why are my xterm menus so small (sic) ?
|
|
|
|
You are probably setting the geometry small accidentally. If you give
|
|
a resource specification like this:
|
|
xterm*geometry: 80x24
|
|
then you are asking for all widgets under xterm to have their geometry set to
|
|
80x24. For the main window, this is OK, as it uses characters for its size.
|
|
But its popup menus don't; they are in pixels and show up small. To set only
|
|
the terminal widget to have the specified geometry, name it explicitly:
|
|
xterm*VT100.geometry: 80x24

You could paste it into an xterm after executing the lpr command.
|
|
However, a program by Richard Hesketh (rlh2@ukc.ac.uk) specifically for
|
|
manipulating the selection will help; e.g.
|
|
% xselection PRIMARY | lpr
|
|
finds the primary selection and prints it.
|
|
This command can be placed in a window-manager menu or in
|
|
shell-scripts. xselection also permits the setting of the selection and other
|
|
properties. A version is on ftp.x.org.
|
|
Also available is ria.ccs.uwo.ca:pub/xget_selection.tar.Z, which can
|
|
be adapted to do this.

Subject: 31) Where are the resources loaded from?
|
|
|
|
The resources of a widget are filled in from the following places (from
|
|
highest priority to lowest priority):
|
|
|
|
1. Args passed at creation time.
|
|
2. Command line arguments.
|
|
3. User's per host defaults file
|
|
4. User's defaults file.
|
|
5. User's per application default file.
|
|
6. System wide per application default file.
|
|
|
|
Note that 2-6 are read only once on application startup. The result of steps
|
|
3-6 is a single resource database used for further queries.
|
|
|
|
Please see the comp.windows.x.intrinsics FAQ, from which this information is
|
|
abstracted, for a full explanation of how to specify the location of files;
|
|
see also a good book on Xt, such as ORA's Volume 4, the Asente/Swick book, or
|
|
the Xt documentation, for more information.
|
|
|
|
----------------------------------------------------------------------
|
|
Subject: 32) How does Xt use environment variables in loading resources?
|
|
|
|
You can use several environment variables to control how resources are
|
|
loaded for your Xt-based programs -- XFILESEARCHPATH, XUSERFILESEARCHPATH, and
|
|
XAPPLRESDIR. These environment variables control where Xt looks for
|
|
application-defaults files as an application is initializing. Xt loads at
|
|
most one app-defaults file from the path defined in XFILESEARCHPATH and
|
|
another from the path defined in XUSERFILESEARCHPATH.
|
|
|
|
XAPPLRESDIR existed in R3 and before. As of R4, the Xt developers
|
|
added the more sophisticated *SEARCHPATH mechanism, but left XAPPLRESDIR in
|
|
place to avoid breaking existing software.
|
|
|
|
Set XFILESEARCHPATH if software is installed on your system in such a
|
|
way that app-defaults files appear in several different directory
|
|
hierarchies. Suppose, for example, that you are running Sun's Open Windows,
|
|
and you also have some R4 X applications installed in
|
|
/usr/lib/X11/app-defaults. You could set a value like this for
|
|
XFILESEARCHPATH, and it would cause Xt to look up app-defaults files in both
|
|
/usr/lib/X11 and /usr/openwin/lib (or wherever your OPENWINHOME is located):
|
|
setenv XFILESEARCHPATH /usr/lib/X11/%T/%N:$OPENWINHOME/lib/%T/%N
|
|
|
|
The value of this environment variable is a colon-separated list of
|
|
pathnames. The pathnames contain replacement characters as follows (see
|
|
XtResolvePathname()):
|
|
|
|
%N The value of the filename parameter, or the
|
|
application's class name.
|
|
%T The value of the file "type". In this case, the
|
|
literal string "app-defaults"
|
|
%C customization resource (R5/R6 only)
|
|
%D site default value for XFILESEARCHPATH (R6 only)
|
|
%S Suffix. None for app-defaults.
|
|
%L Language, locale, and codeset (e.g. "ja_JP.EUC")
|
|
%l Language part of %L (e.g. "ja")
|
|
%t The territory part of the display's language string
|
|
%c The codeset part of the display's language string
|
|
|
|
Let's take apart the example. Suppose the application's class name is
|
|
"Myterm". Also, suppose Open Windows is installed in /usr/openwin.
|
|
(Notice the example omits locale-specific lookup.)
|
|
/usr/lib/X11/%T/%N means /usr/lib/X11/app-defaults/Myterm
|
|
$OPENWINHOME/lib/%T/%N means /usr/openwin/lib/app-defaults/Myterm
|
|
|
|
As the application initializes, Xt tries to open both of the above
|
|
app-defaults files, in the order shown. As soon as it finds one, it reads it
|
|
and uses it, and stops looking for others. The effect of this path is to
|
|
search first in /usr/lib/X11, then in /usr/openwin.
|
|
|
|
Let's consider another example. This time, let's set
|
|
XUSERFILESEARCHPATH so it looks for the file Myterm.ad in the current working
|
|
directory, then for Myterm in the directory ~/app-defaults.
|
|
setenv XUSERFILESEARCHPATH ./%N.ad:$HOME/app-defaults/%N
|
|
|
|
The first path in the list expands to ./Myterm.ad. The second expands
|
|
to $HOME/app-defaults/Myterm. This is a convenient setting for debugging
|
|
because it follows the Imake convention of naming the app-defaults file
|
|
Myterm.ad in the application's source directory, so you can run the
|
|
application from the directory in which you are working and still have the
|
|
resources loaded properly. NOTE: when looking for app-default files with
|
|
XUSERFILESEARCHPATH, for some bizarre reason, neither the type nor file suffix
|
|
is defined so %T and %S are useless.
|
|
|
|
With R5 and R6, there's another twist. You may specify a customization
|
|
resource value. For example, you might run the "myterm" application like
|
|
this:
|
|
myterm -xrm "*customization: -color"
|
|
|
|
If one of your pathname specifications had the value
|
|
"/usr/lib/X11/%T/%N%C" then the expanded pathname would be
|
|
"/usr/lib/X11/app-defaults/Myterm-color" because the %C substitution character
|
|
takes on the value of the customization resource.
|
|
|
|
The default XFILESEARCHPATH, compiled into Xt, is:
|
|
/usr/lib/X11/%L/%T/%N%C:\ (R5)
|
|
/usr/lib/X11/%l/%T/%N%C:\ (R5)
|
|
/usr/lib/X11/%T/%N%C:\ (R5)
|
|
/usr/lib/X11/%L/%T/%N:\
|
|
/usr/lib/X11/%l/%T/%N:\ /usr/lib/X11/%T/%N
|
|
|
|
(Note: some sites replace /usr/lib/X11 with a ProjectRoot in this
|
|
batch of default settings.)
|
|
|
|
The default XUSERFILESEARCHPATH, also compiled into Xt, is
|
|
<root>/%L/%N%C:\ (R5)
|
|
<root>/%l/%N%C:\ (R5)
|
|
<root>/%N%C:\ (R5)
|
|
<root>/%L/%N:\
|
|
<root>/%l/%N:\
|
|
<root>/%N:
|
|
|
|
<root> is either the value of XAPPLRESDIR or the user's home directory
|
|
if XAPPLRESDIR is not set. If you set XUSERFILESEARCHPATH to some value other
|
|
than the default, Xt ignores XAPPLRESDIR altogether.
|
|
|
|
Notice that the quick and dirty way of making your application find
|
|
your app-defaults file in your current working directory is to set XAPPLRESDIR
|
|
to ".", a single dot. In R3, all this machinery worked differently; for R3
|
|
compatibilty, many people set their XAPPLRESDIR value to "./", a dot followed
|
|
by a slash.

Subject: 33) How to I have xdm put a picture behind the log-in window?
|
|
|
|
R5/R6 users can specify the "setup" script that xdm runs by changing the
|
|
entry in the xdm-config file (usually in /usr/lib/X11/xdm) to name a
|
|
different script; the sample script distributed with the X distribution
|
|
simply runs xconsole. See the SETUP PROGRAM section of the xdm man page in
|
|
R6 for precise details.
|
|
|
|
Pre-R5 versions of the xdm client could be spoofed by in changing xdm's xrdb
|
|
resource in the xdm-config file to run a program to change the background
|
|
before loading the resources; for example, your /usr/lib/X11/xdm/xdm-config
|
|
file may add the line
|
|
DisplayManager.0.authorize: false
|
|
to permit unrestricted access to the display before log-in (beware!) and also
|
|
DisplayManager*xrdb: /usr/lib/X11/xdm/new.xrdb
|
|
where that file does something (for all connections) along the lines of:
|
|
#!/bin/sh
|
|
#comes in with arguments: -display :0 -load /usr/lib/X11/xdm/Xresources
|
|
/usr/bin/X11/xsetroot -display $2 -bitmap /usr/lib/X11/xdm/new.bitmap
|
|
/usr/bin/X11/xrdb $*
|
|
Substitute xloadimage or xv for xsetroot, to taste. Note that this is a
|
|
general hack that can be used to invoke a console window or any other client.

Subject: 34) Why isn't my PATH set when xdm runs my .xsession file?
|
|
|
|
When xdm runs your .xsession it doesn't source your .cshrc or .login
|
|
files. You can set the path explicitly as you normally could for any SH
|
|
script; or you can place all environment-setting statements in a separate file
|
|
and source it from both the .xsession file and your shell configuration file;
|
|
or, if you set your PATH in your .cshrc file, the normal place, you can make
|
|
your .xsession have PATH set simply by making it a csh script, i.e. by starting
|
|
your .xsession file off with "#!/bin/csh".
|
|
If this doesn't work, also try starting off with:
|
|
#!/bin/sh # Reset path: PATH=`csh -c 'echo $PATH'` ; export PATH
|
|

|
Subject: 35) How do I keep my $DISPLAY when I rlogin to another machine?
|
|
|
|
There are several ways to avoid having to do a "setenv DISPLAY ..." whenever
|
|
you log in to another networked UNIX machine running X.
|
|
|
|
A trivial solution, if your account is cross-mounted on both machines, is to
|
|
have your .xsession write your DISPLAY variable to a file, and then in your
|
|
login dot-files to check for the existence of that that file and use its
|
|
contents as your DISPLAY. [Thanks to joachim.fricker@zh014.ubs.ubs.ch.]
|
|
|
|
One solution is to use the clients/xrsh on the R5 and R6 contrib tapes. It
|
|
includes xrsh, a script to start an X application on remote machine, and
|
|
xrlogin, a script to start a local xterm running rlogin to a remote machine.
|
|
A more recent version is on export in contrib/utilities/xrsh-5.8.shar.gz
|
|
[21/94].
|
|
|
|
One solution is to use the xrlogin program from der Mouse
|
|
(mouse@larry.mcrcim.mcgill.edu). You can ftp caveat-emptor versions from
|
|
ftp.cim.mcgill.ca (132.206.4.7) in pub/people/mouse/X/xrlogin/. The program
|
|
packages up $TERM and $DISPLAY into a single string, which is stuffed into
|
|
$TERM. rlogin then propagates $TERM normally; your .cshrc on the remote
|
|
machine should contain
|
|
|
|
eval `xrlogind`
|
|
|
|
where xrlogind is a program that checks $TERM and if it is of the special
|
|
format it recognizes, unpacks it and spits out setenv and unsetenv commands
|
|
to recreate the environment variables. [11/90]
|
|
|
|
In addition, if all you need to do is start a remote X process on another
|
|
host, and you find
|
|
|
|
rsh <HOST> -n /usr/bin/X11/xterm -display $DISPLAY
|
|
|
|
too simple (DISPLAY must have your real hostname), then this version of xrsh
|
|
can be used to start up remote X processes. The equivalent usage would be
|
|
|
|
xrsh <HOST> xterm
|
|
|
|
#! /bin/sh
|
|
# start an X11 process on another host
|
|
# Date: 8 Dec 88 06:29:34 GMT
|

# From: Chris Torek <chris@mimsy.umd.edu>

# but they put the rcmd in ()'s which left zombies again. This

Subject: 36) How can I design my own font?
|
|
|
|
One way is to use the "bitmap" client or some other bitmap-editor
|
|
(e.g. Sun's icon-editor tool, post-processed with pbmplus) to design the
|
|
individual characters and then to do some large amount of post-processing to
|
|
concatenate them into the BDF format. See Ollie Jones's article in the
|
|
November 91 X Journal for more information.
|
|
|
|
The R3 contrib/ area (in fonts/utils/ and in clients/xtroff) contained
|
|
a number of useful utilities, including some to convert between BDF font
|
|
format and a simple character format which can be edited with any text
|
|
editor.
|
|
|
|
An easier way is to use the "xfed" client to modify an existing font;
|
|
a version is on the R4 or R5 X11R5 contrib tape in contrib/clients/xfed. Xfed
|
|
was last seen on ftp.Informatik.Uni-Dortmund.DE [129.217.64.63], possibly as
|
|
file /pub/windows/X/Diverse-X11-Sourcen/xfed.tar.Z. It can produce BDF-format
|
|
fonts which can be compiled for a variety of X servers.
|
|
|
|
IBM machines appear to have a utility "fontutil".
|
|
|
|
The xfedor client from Group Bull permits creation of bitmaps,
|
|
cursors, XPM1 pixmaps, and fonts. Binaries for common machines are on
|
|
avahi.inria.fr in /pub; in addition, the sources (an old Xlib implementation)
|
|
have been placed [5/91] in ftp.x.org:/contrib.
|
|
|
|
If you are a MetaFont user you can use "mftobdf" from the SeeTeX
|
|
distribution to convert PK, GF, and PXL fonts to BDF format; the distribution
|
|
is on ftp.cs.colorado.edu and on ftp.x.org.
|
|
The GNU package fontutils-0.4.tar.Z on prep.ai.mit.edu includes xbfe,
|
|
a font editor, and a number of utilities for massaging font formats.
|
|
The O'Reilly X Resource issue #2 contains an article on using these
|
|
tools to modify a font.
|
|
|
|
Fonts can be resized with Hiroto Kagotani's bdfresize; a new version
|
|
is in ftp.cs.titech.ac.jp:/X11/contrib. bdffont in the Andrew User Interface
|
|
System (versions 5.2.2 and higher) lets you create a font or edit an existing
|
|
one.
|
|
|
|
----------------------------------------------------------------------
|
|
Subject: 37) Why does adding a font to the server not work (sic)?
|
|
|
|
After you have built the font using your system's font-compiler,
|
|
installed it in some directory, and run `mkfontdir` or your system's
|
|
equivalent (e.g. bldfamily for OpenWindows) in that directory, be sure to use
|
|
`xset +fp $dir` to add that full path-name to the server's font-path, *or* if
|
|
the directory is already in the path, use `xset fp rehash` so that the new
|
|
fonts in that directory are actually found; it is this last step that you're
|
|
probably leaving out. (You can also use `xset q` to make sure that that
|
|
directory is in the path.)
|
|
Sometimes your "xset +fp $dir" command fails with a BadValue error:
|
|
X Error of failed request:BadValue
|
|
(integer parameter out of range for operation)
|
|
Major opcode of failed request: 51 (X_SetFontPath)
|
|
|
|
This means the X server cannot find or read your font directory, or
|
|
that your directory does not look like a font directory to the server. (The
|
|
mention of an "integer parameter" in the message is spurious.)
|
|
|
|
-- Is the font directory you're specifying readable from the SERVER's file
|
|
system? Remember, it's the server, not the client, which interprets your
|
|
font directory. Trouble in this area is especially likely when you issue
|
|
an xset command with shell metacharacters in it (e.g. "xset +fp ~/myfonts")
|
|
and the server is an X terminal or managed by xdm.
|
|
|
|
-- Is the directory really a font directory? If you're running the sample X
|
|
server (or most varieties of vendor servers) look in the directory for the
|
|
file "fonts.dir". If you can't find that file, run mkfontdir(1). (If you're
|
|
running OpenWindows, look for the file "Families.list". If you can't find
|
|
it, run bldfamily(1).)
|
|
|
|
-- If you're in a site where some people run X11Rn servers and others run a
|
|
proprietary server with nonstandard font formats (OpenWindows, for
|
|
example), make sure the font directory is right for the server you're
|
|
using. Hint: if the directory contains .pcf and/or .snf files, it won't
|
|
work for Open Windows. If the directory contains .ff and/or .fb files, it
|
|
won't work for X11Rn.

Subject: 38) How do I convert a ".snf" font back to ".bdf" font?
|

|
Subject: 39) What is a general method of getting a font in usable format?
|
|
|
|
der Mouse's getbdf is one solution; it connects to a server and
|
|
produces a .BDF file for any font the server is willing to let it. It can be
|
|
used as an anything-to-BDF converter, but requires access to a server that can
|
|
understand the font file, thus is both more and less powerful than other tools
|
|
such as snftobdf. getbdf is on 132.206.78.1 in X/getbdf.c or available via mail
|
|
from mouse@larry.McRCIM.McGill.EDU. [5/91]
|
|
In addition, the R5/R6 program "fstobdf" can produce bdf for any font
|
|
that the R5 server has access to.

Subject: 40) How do I use DECwindows fonts on my non-DECwindows server?
|
|
|
|
The DECwindows fonts typically don't exist on a non-DEC installation,
|
|
but rewrite rules can be used to alias fonts used by DECwindows applications
|
|
to standard X fonts of similar characteristics and size. Pick up the file
|
|
contrib/DECwindows_on_X11R4_font.aliases from ftp.x.org; this file is for a
|
|
sample R4 server. It can also serve as a starting point for creating a
|
|
similar aliases file for the Open Windows server or other servers which do not
|
|
use the X Consortium's font scheme.
|
|
|
|
----------------------------------------------------------------------
|
|
Subject: 41) How do I get a font name from the structure?

You can't, although you can build up the font properties to rebuild a

description of the font in XLFD format, which should be sufficient.

Subject: 42) How can I set backgroundPixmap in a defaults file?
|
|
I want to be able to do something like this:
|
|
xclock*backgroundPixmap: /usr/include/X11/bitmaps/rootweave
|
|
|
|
You can't do this. The backgroundPixmap resource is a pixmap of the same
|
|
depth as the screen, not a bitmap (which is a pixmap of depth 1). Because of
|
|
this, writing a generic String to Pixmap converter is impossible, since there
|
|
is no accepted convention for a file format for pixmaps. Therefore, neither
|
|
the X Toolkit or the Athena widget set define a String to Pixmap converter;
|
|
because there is no converter you cannot specify this value as a resource.
|
|
The Athena widget set does define a String to Bitmap converter for use in
|
|
many of its widgets, however. 4/90]
|
|
|
|
However, note that a specific converter which encapsulates much of the
|
|
functionality of the xloadimage package by Jim Frost was posted 12/90 by
|
|
Sebastian Wangnick (basti@unido.informatik.uni-dortmund.de); it permits
|
|
loading of a number of image formats as a pixmap.

Subject: 43) How can I make small multi-color pixmap images? (What is XPM?)
|
|
|
|
The leading general-purpose format for small multi-color pixmaps is the XPM
|
|
format used by Groupe Bull in several of its programs, including the GWM
|
|
window manager, by AT&T in its olpixmap editor, and by ICS in its interface
|
|
builder. The XPM distribution includes read/write routines for the simple XPM
|
|
text format. See information on the xpm-talk mailing list above.
|
|
|
|
XPM 3.4e became available in 3/95 and is available from ftp.x.org
|
|
(contrib/libraries/xpm-3.4e.tar.gz) and koala.inria.fr (pub/xpm); older
|
|
versions are on the X contrib tapes.
|
|
|
|
A set of XPM icons collected by Anthony Thyssen
|
|
(anthony@kurango.cit.gu.edu.au) is on ftp.x.org in contrib/AIcons; the
|
|
hobbes-icon-xpm3 collection of XPM icons is on hobbes.nmsu.edu./

Subject: 44) Why can't I override translations? Only the first item works. (sic)
|
|
|
|
You probably have an extra space after the specification of the first
|
|
item, like this:
|
|
basic*text.translations: #override \
|
|
Ctrl<Key>a: beginning-of-line() \n\
|
|
Ctrl<Key>e: end-of-line()
|
|
^ extra space
|
|
The newline after that space is ending the translation definition.

Subject: 45) How can I have a clock show different timezones?
|
|
|
|
One solution is xchron, in Volume 6 of comp.sources.x, which can show
|
|
the time for timezones other than the local one.
|
|
sunclock on ftp.x.org displays a world map with sun/dark areas and
|
|
local and UTC time.
|
|
The OpenWindows clock has a TimeZone property. Modifications to the
|
|
Xaw clock widget to support hour and minute offsets were posted by
|
|
David Herron (david@twg.com).
|
|
A patch for the clock coming with the Xaw3D widgets introduces
|
|
resources hourOffset, minuteOffset, gmt; it can be found at
|
|
ftp.wu-wien.ac.at:pub/src/X11/wafe/xaw3d.Clock.patch.
|
|
|
|
Alternatively, you can probably set the timezone in the shell from
|
|
which you invoke the xclock or oclock, or use a script similar to this:
|
|
#!/bin/sh
|
|
TZ=PST8PDT xclock -name "La-La" 2> /dev/null &
|
|
TZ=EST5EDT xclock -name "Nyah-Nyah" 2> /dev/null &

Subject: 46) I have xmh, but it doesn't work. Where can I get MH?
|
|
|
|
The xmh mail-reader requires the Rand MH mail/message handling system, which
|
|
is not part of the UNIX software distribution for many machines. A list of
|
|
various ftp, uucp, e-mail and US-mail sites for both xmh and MH is given in
|
|
the monthly MH FAQ posted to comp.mail.mh; one source is ics.uci.edu.

Subject: 47) Why am I suddenly unable to connect to my Sun X server?
|
|
After a seemingly random amount of time after the X server has been started,
|
|
no other clients are able to connect to it.
|
|
|
|
The default cron cleanup jobs supplied by Sun (for 4.0.3, at least)
|
|
delete "old" (unreferenced) files from /tmp -- including /tmp/.X11-unix, which
|
|
contains the socket descriptor used by X. The solution is to add "! -type s"
|
|
to the find exclusion in the cron job. [10/90]

Subject: 49) How do I get my Sun Type-[45] keyboard fully supported by Xsun?
|
|
|
|
The R6 Xsun supports Sun Type-[45] keyboards; see the KEYBOARDS section of
|
|
the Xsun man page.
|
|
|
|
Many users wants the Num Lock key to light the Num Lock LED and have the
|
|
appropriate effect on the numeric keypad. The R5 Xsun server as distributed
|
|
by the Consortium doesn't do this but there are two different patches
|
|
available.
|
|
|
|
The first patch is written by Jonathan Lemon and fixes the Num Lock related
|
|
problems. It is available from ftp.x.org in the file
|
|
contrib/Xsun-R5.numlock_patch.Z .
|
|
|
|
The second is written by Martin Forssen and fixes the Num Lock and Compose
|
|
keys and adds support for the different national keyboard layouts for Type-4
|
|
and Type-5 keyboards. This patch is available from ftp.x.org in
|
|
contrib/sunkbd.930314.tar.Z or via email from maf@dtek.chalmers.se.
|
|
|
|
[thanks to Martin Forssen (maf@dtek.chalmers.se or maf@math.chalmers.se),
|
|
8/92]
|
|
|
|
A set of patches by William Bailey (dbgwab@arco.com) was posted to newsgroups
|
|
11/92 to provide support for the Type-5 keyboard.
|
|
|
|
(Note that use of xmodmap to map function and arrow keys can make the Type 5
|
|
keyboard more useful without needing these patches.)

Subject: 50) How do I report bugs in X?
|
|
|
|
Generally, report bugs you find to the organization that supplied you
|
|
with the X Window System. If you received the R6 source distribution
|
|
directly from the Consortium, please read the file xc/bug-report for
|
|
instructions. [Look in mit/bug-report for R5, mit/doc/bugs/bug-report in
|
|
R4.]

|
Subject: 51) Why do I get "Warning: Widget class version mismatch"?
|
|
|
|
This error, which typically goes on to say, "widget 11004 vs.
|
|
intrinsics 11003" indicates that the header files you included when building
|
|
your program didn't match the header files that the Xt library you're linking
|
|
against was built with; check your -I include path and -L link-path to be
|
|
sure.
|
|
However, the problem also occurs when linking against a version of the
|
|
X11R4 Xt library before patch 10; the version number was wrong. Some Sun OW
|
|
systems, in particular, were shipped with the flawed version of the library,
|
|
and applications which link against the library typically give the warnings
|
|
you have seen.

|
Subject: 52) Why does my SPARC say "Mapping cg3c: No such device or address"?
|
|
|
|
The R6 sun ddx uses information returned by the device driver to do
|
|
the right thing, so this problem should go away with R6, but the X Consortium
|
|
does not have this configuration available to test it.
|
|
|
|
This problem comes up on Sun SPARC Classic machines. There is no X
|
|
Consortium fix for this problem, but the correction can be made to X11R5
|
|
sources by editing the file "src/mit/server/ddx/sun/sunCG3C.c". Find the
|
|
second buffer definition that looks like this:
|
|
|
|
typedef struct cg3bc {
|
|
#ifdef sparc
|
|
u_char mpixel[128*1024]; /* bit-per-pixel memory */
|
|
u_char epixel[128*1024]; /* enable plane */
|
|
#endif
|
|
u_char cpixel[CG3B_HEIGHT][CG3B_WIDTH]; /* byte-per-pixel memory */
|
|
} CG3BC, CG3BCRec, *CG3BCPtr;
|
|
|
|
and change the instances of "128*1024" to "96*1024". Then recompile the
|
|
X server.
