I can confirm this workaround is working and have fixed other issues as well (Bug #345119).
However I'm now not able to change the Virtual Setting and it's fixed on 2048 x 2048. The only configuration I have in xorg.conf is: Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" Device "Configured Video Device" SubSection "Display" Virtual 3360 2048 EndSubSection EndSection I have and external monitor of 1920x1200 plus the internal LVDS of 1440x900. Since the release of this patch I'm not able to activate the external monitor. Using randr gives me: Screen 0: minimum 320 x 200, current 1360 x 768, maximum 2048 x 2048 On xorg.0.log I see: (II) intel(0): Defaulting Virtual to 2048 2048 for i965. ** Attachment added: "Xorg.0.log" http://launchpadlibrarian.net/26396291/Xorg.0.log -- [i965] X freezes starting on April 3rd https://bugs.launchpad.net/bugs/359392 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
