I'm running Lucid (x86_64) with the 2.6.34-020634 kernel from kernel- ppa/mainline on a Thinkpad W500 (Radeon HD 3650).
Downloading the proprietary driver from http://www2.ati.com/drivers/linux/ati-driver- installer-10-6-x86.x86_64.run and installing worked for me after adding the attached patch to dkms and using the installer's option to build an ubuntu package. I suppose, up to kernel version 2.6.33 no additional patch should be necessary. Windows now minimize and resize very smoothly. Also memory usage of X is constant (after running X for 1,5 hours), although it is pretty high with 360 mb. ** Patch added: "fglrx-2.6.34-rc4.patch" http://launchpadlibrarian.net/50485252/fglrx-2.6.34-rc4.patch -- [Lucid][Ubuntu 10.04][ATI cards] Slow/freeze windows management (resize, maximise, .etc) with fglrx driver + compositing desktop. https://bugs.launchpad.net/bugs/568988 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to fglrx-installer in ubuntu. _______________________________________________ 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
