which will disable pageflipping (as well as disabling vsync) altogether. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1116587 Title: Lenovo T400: With external monitor the system is rarely working for more than 10 minutes Status in “compiz” package in Ubuntu: Confirmed Status in “linux” package in Ubuntu: Confirmed Status in “xserver-xorg-video-intel” package in Ubuntu: Confirmed Bug description: I have a Lenove Thinkpad T400 with an external monitor (1680x1050) connected. Switching windows, surfing the web, and using the compiz effect that streteches windows when moving them against the border cause my system to freeze. I can still move the mouse, however, nothing is clickable at all. Hoped that todays update to 2.21.0-0ubuntu1 solved, the issue but froze allready twice in 30 minutes. There is nothing in the logs AFAICS.
