Package: gdm
Version: 2.20.9-1
Severity: important
Attempting to run a nested desktop with:
/usr/share/gdm/applications/gdmflexiserver-xnest.desktop
fails silently. The same is true when using the System->Log Out->Switch
User menu option in GNOME.
I was unable to locate any error messages in any system logs, as the
default audit level in the gdm configuration appears to be 0. However,
some manual investigation with both Xnest and Xephyr shows that this is
some kind of authorization error:
$ Xnest :22 & xterm -display :22 &
[1] 19632
[2] 19633
user at localhost:~$ Could not init font path element /usr/share/fonts/X11/cyrillic, removing from list!
AUDIT: Mon Jun 15 02:33:03 2009: 19632 Xnest: client 1 rejected from local host (uid 2000)
No protocol specified
xterm Xt error: Can't open display: :22
Note that XAUTHORITY is in the environment, and that this error is true
whether xhost is allowing all hosts or not. The only way to get Xnest or
Xephyr on my system to run is by passing the -ac flag, which turns off
all access control, which is not really what a reasonable person would
want.
