Binary package hint: xserver-xorg-video-ati
Since the last batch of updates (where all the xorg video drivers got updated), I'm experiencing lagspikes in my ubuntu environment. I've traced this back to Xorg using up to 97% CPU on certain moments. This only happens when I'm using the EXA acceleration method, instead of the default XAA one.
With the default XAA, all works very smoothly. But now, with EXA enabled, Xorg often spikes to 100% CPU, mainly when opening applications, scrolling or opening textfiles, or spawning new GTK widgets.
I'm using the EXA acceleration to be able to playback video when using Compiz. I've also filed a bug to use EXA as default accelerator: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/269357
The Xorg option I used to force EXA:
Option "AccelMethod" "EXA"
System details:
Xorg window system 1:7.4~2ubuntu1
RADEON display driver 1:6.9.0+git20080826.a3cc1d7a-2ubuntu2
Sapphire X1650 Pro
Ubuntu Intreprid, fully updated |
-- UPDATE --
This turned out to be a Xserver bug, which most likely will be patched in the 1.5.2 release of Xserver.
