Xorg log file

Here it is. I don't know on which update exactly this happened because I
usually do not use compiz/GL apps. But this laptop used to work very well with
compiz - i have demoed mplayer with video plugin for friends so I am sure it
was working.
Comment 3 Peter Janakiev 2008-03-09 11:31:56 UTC 
The issue is caused by the kernel side, with the older kernel direct rendering
works great:

This works: Linux localhost.localdomain 2.6.23.15-137.fc8 #1 SMP Sun Feb 10
17:48:34 EST 2008 i686 i686 i386 GNU/Linux
The latest update does not. probably the kernel driver side.
