im having a problem in the latest Ubuntu where my notification pop ups are garbled or blurred.
Need to figure out whats up with that.
And here is the solution
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/416001/comments/13
Requires to edit the xorg.conf file.
from terminal I launch gedit in root mode
gedit /etc/X11/xorg.conf
and then add
Option "AccelMethod" "EXA"
to the Section "Device"
Restart X or reboot.
