It's a known issue that intel driver's 2D performance is horribly bad with EXA compared to XAA. This is even worse with older chipsets like 845G. Unfortunately this is nothing Novell/SUSE can fix and for such old chips I'm afraid that Intel's upstream developers won't address the issue as well. I suggest to use Option "AccelMethod" "XAA" in xorg.conf as before, |
Created attachment 297323 [details] working (old) xorg.conf User-Agent: Mozilla/5.0 (compatible; Konqueror/3.5; Linux) KHTML/3.5.10 (like Gecko) SUSE last week I update my fat client system. It uses an intel 845G onboard graphic card. I also used sax2 to create a new config file for xorg. After that the X server uses up to 100% CPU and I could watch how each letter was printed on the screen. All applications were slow ... I suspected the update be using the xorg packages from the DVD did not help. But after reverting the changes to the xorg.cong file I can use my system again. Reproducible: Always Steps to Reproduce: 1. use sax2 to configure my intel 845G onboard graphic 2. restart X 3. Actual Results: _slow_ system; watching all redraws, ... up to 100% CPU usage Expected Results: fast system; max 15% CPU usage of the X-server
