Computer freezes when using dashboard in Unity 3D

[ckx]

If I login using the default Unity (3D) shell, I can use the dashboard for a while but after a minute or two, the computer freezes. I have to shut down and restart, nothing else works. Presumably, this is associated with my Radeon Xpress 200M graphics card. Unity 2D also doesn't work properly, se https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/848280. I'm using Ubuntu 11.10 beta 1, all updates installed.

Same problem with an ATI Technologies Inc RS480 [Radeon Xpress 200G Series].
Open Dash and just move cursor over icons a few times and the Kernel crashes. Verified by no ssh into computer.

This bug no longer occurs in 11.10 beta-2.

Hey john2-hendrickx,

Hi, thanks for reporting this issue during the development period of
Ubuntu.

I notice there's not been further comments to the bug report since the
release came out, would you mind updating us on the status of it in the
release?

Are you still able to reproduce the issue? If not, do you think the bug
report can be closed, or do you think we should continue tracking it?

[ckx (john2-hendrickx)]

The bug was fixed in 11.10 beta-2 and no longer occurs. The bug report can be closed
