** Description changed: Binary package hint: xserver-xorg-video-intel Steps to reproduce 1) Start laptop (Lenovo T400) with external monitor disconnected. 2) Log into Gnome with compiz enabled 3) Plug in external monitor 4) Enable external monitor (Mirror Screens is unchecked) in the Screen Resolutions Utility and click apply. When this happens I expect my desktop to be extended to the external monitor. Instead the screen is corrupted (photo attached). In this state the mouse pointer moves, but the rest of the screen is frozen. Further I'm unable switch tty. By killing X (ctrl-alt-bksp) I return to GDM. When I log in again, my desktop is extended across both monitors properly with compiz enabled. Further Information This bug does not occur if compiz is not enabled. To get compiz working with dual monitors I applied the patch found in bug 146859. I installed the drivers found in http://ppa.launchpad.net/intel-gfx-testing/ubuntu, but the bug had manifested itself BEFORE those drivers were installed.
