Package: xserver-xorg-video-ati Version: 1:6.7.195-2 This experimental version when loaded onto my current Sid partition causes the same problem as on my Gutsy Ubuntu partition, suprise! It is no damn good. Please do not add it to unstable as is. see: http://bugs.freedesktop.org/show_bug.cgi?id=12844 and: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-driver-ati/+bug/152312
