I've just collected a report from a really unhelpful user who after much ranting about 12.04 agreed to tell me that he has an nvidia GE6200 graphics adaptor. I can't get any more information from him and he has now wiped 12.04 and put 11.10 back. He says that 11.10 works perfectly but 12.04 crashes compiz. He didn't note the error messages and all I can get from him now is a rant. Maybe it's worth me noting this here.

I have a GeForce GT430 and still running 12.04, I Installed from 12.04
Beta2 and have just done the updates. Anything I can do to help you just
ask.

Thanks for taking time to report this bug and helping to make ubuntu better. Its been a while since this bug was reported, there have been alot of changes in Unity since then. Can you please test with Ubuntu 12.04 with all updates installed and let us know if the issue is still there.

I have not had this issue in a while so I believe the updates have resolved
this issue.

Thank you.
