Subject: -1- DISPLAYS AND DGL
Date: 15 May 1994 00:00:01 EST
This section discusses how to use remote displays.
------------------------------
Subject: -2- How can I run a program on one machine and display it on
another?
Date: 07 May 1993 00:00:01 EST
Specify the host on which you want the X client to be displayed, then
run the application. To specify a remote host,
setenv DISPLAY <destination>:0
where <destination> is the name or IP address of the remote host. To
specify the local host (console),
setenv DISPLAY :0
------------------------------
Subject: -3- Does the DISPLAY environment variable work for GL
applications?
Date: 4 Jun 1997 00:00:01 EST
Yes: IRIX 4.0.x and later uses the Distributed Graphics Library (DGL)
to allow GL programs to run remotely. Applications running over
DGL use the DISPLAY environment variable just as do ordinary X
applications.
OpenGL applications also will pay attention to the DISPLAY variable.
OpenGL data, however, does not use DGL; it uses the standard X
communications mechanism.
------------------------------
Subject: -4- Why doesn't the DISPLAY environment variable seem to
work?
Date: 4 Jun 1997 00:00:01 EST
First, make sure your DISPLAY variable is syntactically correct. For
example, to display applications on a machine named "enterprise",
whose IP address is 123.45.678.90, DISPLAY should be set to
"enterprise:0" or "123.45.678.90:0".
Next, try to "ping" the machine to which your DISPLAY variable is
set. If this does not work, you have either specified an invalid
hostname, the host is down, or you are having network problems.
If you are running an older binary that expects to see /etc/resolv.conf
in /usr/etc, you will either have to make a symbolic link from
/usr/etc/resolv.conf to /etc/resolv.conf, or set the DISPLAY variable
with a numeric address.
If you see messages like "permission denied" or "can't connect to
server", you have a permission problem. Do 'xhost +yourmachine' on
the remote machine to give 'yourmachine' access to the remote
machine's display. (Note that 'xhost' is inactive by default on
SGIs.)
If you're using NIS (YP), make sure the client is linked with
"-lsun".
For more information see Chapter 3 of the X Window System User's
Guide.
------------------------------
Subject: -5- Why do I get DGL errors when I try to run a GL program?
Date: 4 Jun 1997 00:00:01 EST
- There may be a problem with the DISPLAY variable or Xwindows
permissions. See the previous question.
- You may be trying to display on a non-SGI machine which doesn't
support GL/DGL. Note that DGL is for running GL programs remotely,
not OpenGL programs. OpenGL programs run remotely via the
GLX X server extension.
- DGL may be disabled in /etc/services and/or /etc/inetd.conf. The
former file should have a line reading
sgi-dgl 5232/tcp
and the latter should have a line reading
sgi-dgl stream tcp nowait root /usr/etc/dgld dgld -IM -tDGLTSOCKET
If either is commented out, remove the comment.
- You may be trying to display on a machine with a much older version
of IRIX. Try another machine with a newer IRIX.
An article in the Jan/Feb 1993 Pipeline describes the above in great
detail.
------------------------------
Subject: -6- CUSTOMIZING
Date: 15 May 1994 00:00:01 EST
This section discusses ways to customize your environment, both with
and without graphics. The next two sections go into depth on
customizing Xwindows resources and the 4Dwm.
------------------------------
Subject: -7- What tools does SGI provide to help with the
customization process?
Date: 05 Jul 1994 00:00:01 EST
Here are some good places to look in IRIX 4.0.x:
- The Customization rollover menu in the Toolchest.
- The manpages for xfontsel, xlsfonts, xwininfo, xdpyinfo, xprop,
appres, listres, and xrdb.
- The "WorkSpace User's Guide".
- The example files in /usr/tutor/Customize.
In IRIX 5.x, take the systemtour and keep your eyes open.
------------------------------
Subject: -8- What are the important login and resource files for IRIX
4.0.x?
Date: 07 May 1993 00:00:01 EST
The following three file groupings indicate where files that affect
your login session reside.
1) /usr/lib/X11/* - This is THE starting place. Here you find the
system default bindings for Motif, 4Dwm, and the Toolchest. The xdm
directory lives here as well as the app-defaults directory. xdm
controls the session management. Many application defaults are set in
the app-defaults directory.
2) $HOME/[.Xdefaults, .4Dwmrc, .chestrc, .xsession, .sgisession] Here
you find the files that control your system set-up. You create these
files; they don't exist when you first log in.
3) /usr/bin/X11 - This is where the binaries live. It makes life nice
to include this directory in your path.
------------------------------
Subject: -9- What is the sequence of events that occur at login time
in IRIX 4.0.x?
Date: 10 Dec 1993 00:00:01 EST
This is a bare bones synopsis of the events that occur when you log
in to the console via xdm (the default method of logging in) under
IRIX 4.0.x and, with the desktop *disabled*, IRIX 5.x.
1) Provide a "failsafe" (nographics) login if required/requested.
2) Exec $HOME/.xsession if it exists. If it exists, the remaining
steps should normally be included in the users .xsession file
as well.
3) Load $HOME/.Xresources if it exists.
4) Set XUSERFILESEARCHPATH.
5) Incorporate a "shell" environment into the "session".
(man userenv)
6) Set the root background and cursor.
7) Disable display access control (xhost +). (man xhost)
8) Start 4Dwm.
9) Wait for 4Dwm to come up.
10) Start the console.
11) Execute $HOME/.sgisession if it exists.
12) Start WorkSpace if the user wants it.
13) Put a Toolchest on each screen.
14) Exec the "reaper". (man reaper / endsession)
------------------------------
Subject: -10- What is the difference between .xsession and .sgisession
in IRIX 4.0.x?
Date: 07 May 1993 00:00:01 EST
The system Xsession file (/usr/lib/X11/xdm/Xsession or
Xsession-remote) starts up a number of important things when you log
in, eg. 4Dwm, toolchest, loads resources, sets your
XUSERFILESEARCHPATH, sets your root background, etc.
One of the last things it does is look in your home directory for a
.sgisession file. This allows you to start additional programs at
login time. This is the file that you would use to start a mailbox,
additional window, a calendar, etc.
ADVANTAGES OF $HOME/.sgisession :
1) You don't need to read through yet another system file to see
what you need or don't need.
DISADVANTAGES OF $HOME/.sgisession :
1) You cannot override ALL of the defaults set for you. Some
things you can't change from a .sgisession file:
A) You can't start a different window manager.
B) You can't change the way the console starts.
C) You can't change toolchest output redirection to
the console.
2) Users of other vendors' equipment are used to seeing a
.xsession file.
After checking for a "failsafe" (ie. no graphics) login, one of the
first things that /usr/lib/X11/xdm/Xsession does is check for
$HOME/.xsession. If it exists, Xsession execs your .xsession file.
This means that if you are REALLY sure you know what you are doing,
you can log in with a different window manager, xterm as a console,
or xwsh not already iconified, etc. You can also turn off the
toolchest output redirection, and start anything else you might have
done in $HOME/.sgisession. There is a discussion on xsession files in
volume 3 of the O'Reilly series.
------------------------------
Subject: -11- Why do 4Dwm, toolchest, Workspace, etc. not recognize an
environment variable I set in my shell's startup files
in IRIX 4.0.x?
Date: 03 Sep 1995 00:00:01 EST
The script /usr/lib/X11/xdm/Xsession (or, if you have one, your own
~/.xsession) runs when you log in and starts your window manager
(4Dwm), Workspace, etc. To give these programs a copy of the
environment you define in your shell's startup files, Xsession first
runs 'userenv', which runs your shell just to see what environment
variables your shell's startup files set and puts them into
Xsession's environment. Later on Xsession runs 4Dwm, Workspace, etc.
and they inherit Xsession's environment including the environment
variables which 'userenv' got from your shell's startup files.
However, 'userenv' objects to 1) errors in your shell startup files,
2) commands which print output to the terminal and 3) commands like
'stty' and 'tset', which expect to be connected to a terminal. Any
of these may cause 'userenv' to give up completely, so that Xsession,
4Dwm, Workspace, etc. do not get any of your shell's enviroment.
To get 'userenv' to work, you must 1) make sure that your shell
startup files are error-free and 2) protect 'userenv' from commands
which print output or expect to be connected to a terminal by testing
for the ENVONLY environment variable before running them. (See the
userenv(1) manpage.) You might try disabling your shell startup files
(or parts thereof) one by one to narrow down which is causing the
problem. Be sure to check both personal and system-wide shell
startup files! See your shell's manpage for a complete list.
Note that each terminal window (aka 'winterm', 'xwsh' or 'xterm')
runs a fresh copy of your shell, so it has a second chance to set
your environment variables. Your shell is now connected to a terminal
and 'userenv' isn't involved, so none of the above problems apply.
The environment in a terminal window will appear correct, and
programs started from a window (e.g. by typing 'workspace' to start
Workspace) will inherit the environment properly. Furthermore,
'userenv' often appears to work when run inside a terminal window,
even when it does not work when run from Xsession. This is all fine,
but it doesn't help when you log in. One right way to see if
'userenv' is working when it should is to add the line 'env >
$HOME/test-userenv' to Xsession after the line that runs 'userenv',
log in and examine the file it creates.
'bash' users take note: 'bash' has particular problems with 'userenv',
and there is a special version of 'userenv' which works with 'bash' at
ftp://viz.tamu.edu/pub/sgi/software/desktop/userenv.tar.gz.
------------------------------
Subject: -12- How can I change desktops without using the mouse and
Desks Overview?
Date: 8 Mar 1997 00:00:01 CST
Ping Huang <pshuang@sgi.com> contributes the following method:
Unlike some other window managers, you can't navigate between
desktops geographically, using some Control, Alt, and/or Shift'ed
version of the arrow keys. However, you can tell 4Dwm to let you jump
to a given desktop with a keystroke. If you want to customize one
account only, copy /usr/lib/X11/system.4Dwmrc (or possibly
/usr/lib/X11/$LANG/system.4Dwmrc, if you set the LANG environment
variable for localization) to the user's home directory as .4Dwmrc.
Look for the "Keys 4DwmKeyBindings" section, and add lines of the
following form:
# IndigoMagic desktops
<Key>F1 root|icon|window f.switch_desk "Desk 1"
<Key>F2 root|icon|window f.switch_desk "Desk 2"
<Key>F3 root|icon|window f.switch_desk "Desk 3"
<Key>F10 root|icon|window f.switch_desk "Global"
The names of the desks are whatever arbitrary names you used to name
your desks in Desk Overview. (The "Global" desk is, however, a special
desk; see Desk Overview help for details. You still reference its
name here as you would any other desk.)
------------------------------
Subject: -13- How can I turn off the IRIX 5.2 Magic user environment?
Date: 18 Aug 1994 00:00:01 EST
Mark Andrews <mark@alias.com> says:
You can disable the Indigo Magic environment in two ways:
1) If you wish to disable it for all users on the machine:
chkconfig desktop off
2) If you wish to disable it for a specific user, do
touch ~<username>/.disableDesktop
You may also have to remove the ~/.desktop-<hostname> directory as
well as 4Dwm looks in there for a 4Dwmsession file which it uses
for a guide to redisplay windows left open from the last session.
Method 2 works ONLY if you have the original IRIX 5.2 xdm Xsession
file, which contains the following code chunk:
if /etc/chkconfig desktop ;
then
if [ -x $0.dt -a \! -f $HOME/.disableDesktop ]
then
exec $0.dt $*
fi
fi
If you only want to turn off the file manager, create the file
~/.desktop-<hostname>/nodesktop.
Whether you disable the entire desktop or just the file manager, you
may also want to set one or more of these resources
4DWm*SG_autoSave: false
4Dwm*SG_manageSession: false
4Dwm*SG_useBackgrounds: false
which are explained in the 4Dwm(1) manpage. See also the desktop_eoe
release notes.
------------------------------
Subject: -14- How can I display my own background image under Indigo
Magic?
Date: 30 Apr 1995 00:00:01 EST
Two SGI employees described two different ways to do this, one for
folks who don't care about desktop icons and one for folks who do.
Joel Tesler of SGI <joel@sgi.com> says:
1) Disable Indigo Magic desktop icons in any of the three ways
(~/.desktop-<host>/nodesktop, ~/.disableDesktop, or 'chkconfig
desktop off') described in the previous entry.
2) Set the resource
4Dwm*SG_useBackgrounds: false
3) Run whatever command you like to display the image on the
background.
Jon Madison of SGI <jm@indianapolis.sgi.com> says:
1) cp /usr/lib/X11/system.backgrounds ~/.backgrounds
2) Read your new ~/.backgrounds file (and 'man background') to see
how it works, and edit it. Here's an example entry which uses
'xli' (a free image viewer) to display a GIF image:
background "Legos"
command "-execute /usr/local/bin/xli -onroot -fork /usr/people/jm/graphics/pix/lego.gif"
default "-execute /usr/local/bin/xli -onroot -fork /usr/people/jm/graphics/pix/lego.gif"
exeok "/usr/local/bin/xli"
readok "/usr/people/jm/graphics/pix/lego.gif"
3) Run the 'background' customization panel. (It's in the default
toolchest. Hey, there's your custom background in the list!
Backgrounds set up in this way coexist fine with desktop icons.
------------------------------
Subject: -15- Where is the default value of PATH set?
Date: 10 Dec 1993 00:00:01 EST
Every program which allows a user to log in (telnet, rlogin, pandora,
etc.) can specify PATH. Shells may as well if it isn't already set.
There are many slightly different default values, and relying on them
is a good way to get confused. The only reliable method is to set
PATH in your shell's startup files. These are different for each
shell, and are described in each shell's manpage. Beware of 'ksh',
which has an internal, invisible default path ('/bin:/usr/bin') which
it uses when PATH is not set.
------------------------------
Subject: -16- Why can't I log in after copying
/usr/lib/X11/xdm/Xsession to .xsession?
Date: 07 May 1993 00:00:01 EST
After copying this file to your home directory, you need to remove
all references to "xsession". References to xsession cause the system
to try to execute $HOME/.xsession, which will create an infinite
loop.
Remove the lines in ~/.xsession that say:
if [ -r $xsession -a "$0" != $xsession ]; then
if [ -x $xsession ]; then
exec $xsession
else
exec /bin/sh $xsession
fi
fi
------------------------------
Subject: -17- How can I find out what fonts are available?
Date: 07 May 1993 00:00:01 EST
The xfontsel and xlsfonts utilities help you find appropriate fonts.
xlsfonts lists the fonts; xfontsel provides an interface for
selecting a desired font. To use xfontsel, choose "Font Names" from
the Customization rollover menu in the Toolchest. Please see the man
pages and the IRIS Utilities Guide for further information.
------------------------------
Subject: -18- How can I use the Alt key as a Meta key in an xwsh
window?
Date: 23 Jun 1994 00:00:01 EST
First, put the following X resources wherever you put X resources:
--- beginning of resources ---
! This turns Alt-key into Meta-key.
XWsh*metaKeyMask: 8
! This allows multiple key modifiers in keybindings (so we can do
! meta-shift, meta-control, etc. and incidentally a) turns vt100
! cursor key mode off and b) changes the cursor key bindings.
XWsh*keyboardType: xlib
! This turns vt100 cursor key mode back on. Running 'tset' at login
! resets the terminal and turns the cursor keys back off, so don't
! run it.
XWsh*initSequence: \233?1h
! The iris-ansi terminfo entry has arrow key sequences for the ibmrt
! keyboard, not the xlib keyboard; for curses applications to work,
! the arrow keys must be bound to the sequences in the terminfo
! entry. Rebinding the arrow keys to match the terminfo entry is more
! convenient than changing the terminfo entry.
XWsh*ckmeKeyMap: \
Left(any): send("\033[D"); \
Right(any): send("\033[C"); \
Up(any): send("\033[A"); \
Down(any): send("\033[B");
--- end of resources ---
'tset' resets your terminal, so running it will undo the initSequence
resource setting. There is a 'tset' command in the default csh/tcsh
~/.login file; replace the line
eval `tset -s -Q`
with
if (! $?TERM) then
eval `tset -s -Q`
endif
so 'tset' will run only if the TERM environment variable isn't
already set. (You can't say 'if (! $?TERM) eval `tset -sQ`', because
csh/tcsh evaluates the backquotes *before* the if.)
Finally, if you use GNU Emacs, put the following in your .emacs:
(set-input-mode nil nil t)
This tells Emacs to allow Meta key usage even though the iris-ansi
(xwsh) terminal description doesn't specify a Meta key.
------------------------------
Subject: -19- How can I configure my keyboard like a VT100?
Date: 4 Jun 1997 00:00:01 EST
'xwsh -vt100' may be close enough; try it and see. (The PF keys are
mapped to F9-F12.) If not, use 'xterm -name VT200' and put the
following wherever you put the rest of your X resources:
=== snip ===
XTerm*VT200.Translations: #override \
<Key>BackSpace: string(0x7f) \n\
<Key>Num_Lock: string(0x1b) string("OP") \n\
<Key>KP_Divide: string(0x1b) string("OQ") \n\
<Key>KP_Multiply: string(0x1b) string("OR") \n\
<Key>KP_Subtract: string(0x1b) string("OS") \n\
<Key>KP_Add: string(0x1b) string("Om") \n\
