I'm having a similar problem with the update. I have an external monitor plugged into my laptop (Asus W6A) which has a i915GM.
After upgrading I observe the following: - blue/red stripes appeared on the LVDS display. - the external display's brightness gets set to the maximum. Downgrading to 2.4.1-1ubuntu10 works fine. 00:00.0 Host bridge: Intel Corporation Mobile 915GM/PM/GMS/910GML Express Processor to DRAM Controller (rev 04) 00:02.0 VGA compatible controller: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 04) 00:02.1 Display controller: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 04) ** Attachment added: "lspci -vvvnn" http://launchpadlibrarian.net/21765952/file -- [i915GM] Regression in xserver-xorg-video-intel version 2.4.1-1ubuntu10.3 https://bugs.launchpad.net/bugs/320893 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
