Turns out this was/is a problem with a new version of xserver-xorg-video-intel. The problem disappears when using vesa driver or downgrading to an older version of xserver-xorg-video-intel.
For anyone interested: I have an Intel X3100 (GM965) and xserver-xorg-video-intel Version 2:2.2.0-1 does not work (problem description see post above) xserver-xorg-video-intel Version 2:2.1.1-4 does work -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
