[Bug 36321] Re: Incomplete logout options with XGL

[Bazon]

This happens to me, too, and I'd like to add how XGL is started exactly to make it better reproduceable:
A new xsession is created:
/usr/share/xsessions/xgl.desktop

containing:

[Desktop Entry] 
Encoding=UTF-8 
Name=XGl 
Exec=/usr/bin/startxgl.sh 
Icon= 
Type=Application

where /usr/bin/startxgl.sh is the script which actually starts xgl and
looks in a minimal case (not starting compiz withit) like this:

#!/bin/bash

Xgl -fullscreen :1 -ac -accel glx:pbuffer -accel xv:fbo & sleep 2 &&
DISPLAY=:1 gnome-session

This is a popular method to start XGL, as it leaves you the option to
start a normal Xorg Session from GDM.

It is reported e.g.:
