Comment 52 for bug 568988

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.
