Comment 58 for bug 348332

Dear Bram Willemsen,

please read the whole bug report, you will notice that you have a few opportunities to solve this problem..

Either you downgrade your xsever to version 1.5.2 that way you can use fglrx or radeon, packages are provided as a archived package in a link more up in this Bugreport...
2nd you can also update your kernel to a 2.6.29 or .30 release using the Ubuntu Vanilla kernel PPA (Ubuntu Mainline Kernel) and upgrade your radeon driver and X with this PPA https://edge.launchpad.net/~ubuntu-x-swat/+archive/x-updates/ wich was reported also to be successful..

Also let us know if you are using either KDE or Gnome as your desktop of choice? As this bug "so far" seems to be kubuntu related only..
