I hate an issue in Debian Lenny that sounds a lot like this, just wanted to comment that AccelMethod "XAA" in my device section solved it for me.
I was having VERY slow rendering times in Firefox. Switching tabs would take forever. My computer did not feel like it should. I'm on a Thinkpad X61s with lspci graphics card line: 00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c) My xorg.conf is largely autoconfigure (except for one Keyboard options line to replace caps lock with control). I ONLY added the AccelMethod "XAA" line to my device section to get this: Section "Device" Identifier "Configured Video Device" Option "AccelMethod" "XAA" EndSection And suddenly firefox is incredibly fast again. In fact, I didn't notice this before but ALL GTK apps were slow and they are all faster. I think this might technically be an xorg auto config problem? I also think a lot of the problems in this bug report might not be for the same actual bug. -- Firefox causes massive Xorg CPU usage https://bugs.launchpad.net/bugs/38131 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
