[ATI 9100] Unity Side Bar Freezes

[PVLP]

I have just updated my Acer Travelmate 2200 from Ubuntu 10.04 Netbook Remix to the the new 10.10 version.
I used the automatic update which has kept all my old settings.
Now I cannot use the new side bar as it frezes and I get a black screen blinking once. I do see all the Icons in the bar: they open and close, there are arrows for opened windows, but I cannot click on any of them.
Even in the top bar I cannot right click. I can only click to close or minimize windows.

Here follow a few details of my hardware:

Is there a way to go back to the previous version or something that can fix the problem now?

Unity/mutter has known issue on ATI hw. Natty will use Unity on compiz and should fix that, do not hesitate to report if you still have the issue there with the Natty version when alpha1 is available.

Hi, as Natty Alpha 1 will be out this week, could you please test Unity on that to see if it works smoothly and artifact-free on your system? We've been working hard to fix Ati support and hopefully this issue is resolved for you. I'll mark this as incomplete pending your results, thanks.

Hi!
Thank you very much for your hard work, but unfortunately I cannot test it. My
laptop seems to have died last Friday. I cannot log on to neither Ubuntu nor
Windows. I tried mounting a different internal HD drive, I tried removing RAM, I
tried to load Ubuntu Live CD, but I always get stuck at the same point when
loading the OS and the system reboots automatically. I take there's something
wrong with the motherboard or with the power pack and I don't have enough
technical knowledge, nor the tools, to repair that.
Hopefully your hard work will be of help to others as it seems there are plenty
of people having issues with ATI graphic cards.

Thank you again and Best Regards,
Samuele D'Amico
