This problem has been plaguing me ever since 7.2 hit the repos. I'm running feisty on a ThinkPad T43p with ATI FireGL V3200 using the open- source ati driver and aiglx. Beryl and Compiz are unusable.
Conn's description of the problem using Firefox and gnome-terminal apply to my machine also. I'll add that gnome-system-monitor will peg the CPU at 100% when displaying the resource graphs. Following suggestions in this thread: http://www.ubuntuforums.org/showthread.php?t=372693 I first ran sudo dpkg-reconfigure xserver-xorg to create a more "generic" xorg.conf (still using ati, but no aiglx). This gave me a small but noticeable improvement. I next restored my original xorg.conf, but disabled EXA acceleration. This has provided the most notable improvement, but still not quite as good as pre-7.2. Compiz will run without choppiness, but is somewhat flakey when rotating the cube or alt-tabbing. My current xorg.conf is attached. ** Attachment added: "xorg.conf - ati, aiglx, no EXA" http://librarian.launchpad.net/6589671/xorg.conf -- Sluggish rendering since xorg 7.2 update https://launchpad.net/bugs/88815 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
