Screenshot of gdm login screen

SUSE Linux Enterprise Desktop SLED Configure-Administer
1

For our internal documentation I need a screenshot of our custom gdm
login screen of SLED11 SP1. Following several pathes along import,
starting multiple X servers, vncserver, or manipulating Xsession and the
gdm configuration I did achieve basically nothing. Can someone point me
to a description on how to complete this task on this specific
distribution? THX.

Thanks for the hint. This is of many instructions published for Ubuntu
or several other distributions. Up to now none of these worked for
SLED11. Specifically:

linuxpool-13:~ # gdmflexiserver --xnest

** (gdmflexiserver:12791): WARNING **: Not yet implemented
linuxpool-13:~ # gdmflexiserver --help
Usage:
gdmflexiserver [OPTION…] - New GDM login

Help Options:
-h, --help Show help options

Application Options:
-c, --command=COMMAND Ignored - retained for compatibility
-n, --xnest Ignored - retained for compatibility
-l, --no-lock Ignored - retained for compatibility
-d, --debug Debugging output
-a, --authenticate Ignored - retained for compatibility
-s, --startnew Ignored - retained for compatibility

Hi
The problem is in the X authority bit, run the following command on
your tty with gdm running;

ps aux |grep X

You need to use the full string after the -auth as your XAUTHORITY

See example here;
http://paste.opensuse.org/3eb5c820

Note I used xwd for the screen capture.

Thanks, finally this works:
chvt 7; sleep 3; export \
XAUTHORITY=/var/run/gdm/auth-for-gdm-uzAyQH/database ; xwd -root \
-display :0 | convert - /tmp/13_1.png

with the value for XAUTHORITY taken from the output of ps. I had to add
the display option to xwd though.
I also stopped apparmor but did not verify if this was necessary. Thank
you very much again.
