[Bug 375264] Re: [i965] GM965/GL960: video and compiz issues after jaunty upgrade

[Nathan Dorfman]

I am happy to report that almost everything works great after enabling
UXA.  The performance problems are gone, and no stability issues or
memory leaks have surfaced. Suspend and hibernation work fine.

Specifically, I added this single line to xorg.conf:
<     Option "AccelMethod" "UXA"

Driver version:
ii  xserver-xorg-video-intel                   2:2.6.3-0ubuntu9

Also immediately noticeable is that the CPU usage of the Xorg process is
dramatically reduced; even during playback of a 480p movie from Hulu, in
full screen, it's around 10% or less, as opposed to 50-60% (and
unwatchable results). Flash performance, of course, won't be mentioned
in a family forum.

The Reflection Compiz plugin is still broken; it will hang X shortly
after being enabled, just as without UXA. At this point, this is the
only issue I can detect with this configuration. Everything else seems
to be working flawlessly so far.

The Reflection hangs did not occur on the same machine running interpid,
nor do they on a completely different system running jaunty today.

That's all .. thanks, and let me know if I can be of any help.
