Re: comment #12

It sounds OK to disable Xgl if it keeps crashing, I think there should
additionally be some mechanism that restarts gdm explicitly.

Yes, I agree and I think this is already taken care of by my patch as executing
gnome-xgl-switch seem to somehow make gdm restart the X server after displaying
the "Desktop effects disabled" message instead of just shutting it down.

A gdm package with this patch can be downloaded from here:

The quality has changed somewhat. On issuing Xgl :0 -ac from a Terminal I get:

Xgl :0 -ac
/etc/sysconfig/displaymanager: line 160: unexpected EOF while looking for
matching `"'
/etc/sysconfig/displaymanager: line 161: syntax error: unexpected end of file

Fatal server error:
Server is already active for display 0
If this server is no longer running, remove /tmp/.X0-lock
and start again.

Which, apart from telling me gdm is still running, looks somewhat weird with
respect to /etc/sysconfig/displaymanager

Sorry, I forgot to tell you to stop gdm first.

ps -A | grep gdm
10245 ? 00:00:00 gdm
10246 ? 00:00:00 gdm

After shutting gdm down ( not sure why there are two instances running ) and
issuing Xgl :0 -ac 2> xgloutput.txt the screen turns into a crude structured
grey pattern and the mouse pointer is visible and can be moved. Nothing more.

That's the expected behavior and means that Xgl starts up correctly. Not sure
why it doesn't work through gdm. I suspect that direct rendering is not
provided by the Xorg server for some reason. Can you please attach the output
from running 'glxinfo' when desktop effects are disabled.
