Binary package hint: xserver-xorg-driver-ati

arch: amd64
hardware: radeon mobility x700
version: lucid beta1

linux-image-2.6.32-16-generic (2.6.32-16.25)
xserver-xorg-video-ati (1:6.12.191-1ubuntu2)

kms, by default in lucid beta1 is on. system boots flawlessly. after
logged in feels sluggish. tried to turn off effects by navigating to
system > preferences > appearance and immediately system reboots or
freezes (tried multiple times - all with success).

turning kms of (radeon.modeset=0) - no more crashes.

I believe, this is release critical: radeon.modeset=1 not ready for the prime (not the default), or some models need to be blacklisted...
