ATI FGLRX and Logging Off

[Larry Hartman]

Mike:

Bug # 107975 on Launchpad.  The bug reporting tool came up on the last time it 
happened, so I proceded to report it.

My GLXinfo appears to come up properly.  I did get similar GLX/DRI errors 
yesterday from FGLRXinfo when I first started the troubleshooting but somehow 
managed to tweak it out by changes to my xorg.conf.  I had to essentially 
ditch my previous xorg.conf from Kubuntu 6.10 and rebuild from scratch.  Not 
sure what it didn't like from the old file as the new one seems to have all 
of the same elements....  

Does your xorg.conf differ significantly from mine (see first post)?
