[Bug 416001] Re: Notification and similar dialogs are displaying corrupted after update on Karmic

 

After living with this problem for a long time and a few hours of
playing around I found a fix.  I created an xorg.conf file and added one
line to the Device section changing to EXA instead of XAA, leaving all
defaults the same.  Here's the important part:

Section "Device"
        Option     "AccelMethod"                "EXA"
        [...]
EndSection

Why does this work?  For some cards like some models of Mobility Radeon
the developers decided to change the default from EXA to XAA for
performance reasons.  Most other ATI cards default to EXA, but some
default to XAA.  Even if you think you know what it should default to,
double check it.  Changing the AccelMethod fixed my problems.
