Ok it seems to resolve the problems with xserver-xorg-video-intel 2:2.13.901-2ubuntu2~xup~maverick.
But note that with bleeding edge intel-driver from ppa:glasen/intel-driver (2:2.14~glasen~maverick~ppa6), there is still graphics problem with emacs : the cursor takes the shape of the letters (with 'space' character the cursor disappear) !? (and have other refresh problems) And when I disable compositing effects, this problem disappear. I hope this bug will not reappear on a future stable release. -- 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/661910 Title: Kwin compositing problem on maverick _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
