Andres, can you confirm that this happens when booted into Classic Desktop (no effects)? It appears from your bug report that compiz (or kwin compositing) is turned off, but I want to be doubly sure this is true.
The reason is that upstream says that this bug is because there is a 4096x4096 maximum texture hardware limitation for compositing with this Arrandale chip. So you either need to disable compositing, or arrange your screens to not exceed this limit. >From your log files it appears your laptop is 1280x800 and you have a 3840x1080 monitor, which totals to 5120, and since that's larger than 4096 the graphics card can't handle it. (Is this correct, that you have a 3840x1080 monitor?) A way to work around this limitation would be to have your laptop monitor positioned above or below your external monitor. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/737891 Title: [Arrandale] gnome-display-properties unable to correctly enable monitors connected to VGA _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
