Just to add informations : This problem was present in karmic, upgrading to lucid didn't change anything and I tried to manually compile the last stable radeon drivers (xf86-video-ati-6.13.0) and it still doesn't solve the problem.
So, at least for my board : $ sudo lspci | grep VGA 01:00.0 VGA compatible controller: ATI Technologies Inc Radeon RV100 QY [Radeon 7000/VE] with no xorg config file (wich means using EXA acceleration) and using a poor performance CPU, Xorg operations are sluggish, CPU usage is high (sometimes stucked at 100%). I've tried all proposed solutions presented here, disabled all possible "bling bling" effects in gnome/kde and hardly got a few spare CPU cycles. I'm unable to switch to XAA for a test has it seams to be disabled in recent drivers (log files show it doesn't care about my Option "AccelMethod" "XAA" and still talks about using EXA) I'll have a try at finding an old driver version if XAA is still able to be activated with recent xorg version Funny note for the end : It is so sluggish with EXA "acceleration", that I choose to just disable acceleration (Option "NoAccel" "Yes") This gives me better 2D performances, with the drawback of disabling OpenGL wich I need to renable with 2 xorg.conf files whether I want GL or not. Maybe I'll have a try with the vesa driver ? :-) -- [RV100] very poor Xorg performance on various older graphics HW - XAA no longer works https://bugs.launchpad.net/bugs/363238 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
