I also have a similar problem. I have an Intel GMA X4500 HD video card. What I notice is the following:
My intel driver version is: 2:2.7.99.901+git20090702.74227141-0ubuntu1 In KDE 4.3 RC2, with desktop effects enabled, each time I switch desktops, the memory usage of Xorg increases each time. I've attached my Xorg.0.log. ** Attachment added: "Xorg log" http://launchpadlibrarian.net/29019716/Xorg.0.log -- Kubuntu: X becomes sluggish after only 4 open windows https://bugs.launchpad.net/bugs/356438 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in ubuntu. _______________________________________________ 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
