Hello, I recently installed Opensuse 11.1 on a HP Pavilion dv8000 ( with XPRESS 200M graphics ), shipped with Xorg 7.4 (--) RADEON(0): Chipset: "ATI Radeon XPRESS 200M 5955 (PCIE)" (ChipID = 0x5955)
I am experiencing some kind of slow 2D performance, never seen before on any system or previous distro : - sometimes i can clearly see text drawing from top to bottom in a file manager (konqueror) or an editor (kate) - when switching desktops, there's some kind of tearing of the content of the open windows, and when doing so repeadedly, xorg eats more than 60/70% CPU - glxgears gives about 400fps The more open windows in the desktops, the more those symptoms are noticeable. With the default opensuse settings ( no parameters in Device section ie. XAA accel not supported anymore ) it is worse, even Konsole is sluggish. See : http://linux.derkeiler.com/Mailing-Lists/SuSE/2009-02/msg00132.html So I switched to EXA. It is better, but it doesn't really solve. It occurs either with the default xorg 7.4 packages, the latest xorg compiled from sources, or the lastest packages from the opensuse build service. Note : MigrationHeuristic="smart" or "greedy" -seems- to help a bit, but it's not as fast as it was before. With an old opensuse 10.0 with xorg 6.8 (32bit mode if relevant) on the same laptop, everything is stunning fast. With OS 11.1 & xorg 7.4, although it is not really horrible or unusable, there's definitely something wrong, it feels a little sluggish in comparaison. Btw. glxgears gives about 780fps. Find below the xorg.conf and Xorg.log, however everything seems OK, no wierd errors. http://88.191.15.45/Xorg.0.log http://88.191.15.45/xorg.conf Am I missing something ? Any ideas ? Please advise. Could it be because of the new EXA architecture, poorly supported for XPRESS 200M ? The AMD64 architecture ? I am really out of ideas now. If you need further data or testing from my side, I will gladly provide.
