My ubuntu 11.10 destroyed my desktop after running compiz manager and pressing on plugins menu. After pressing, the harddrive was working a lot (at least 5 to 10 minutes). After this, my sidebar disappeared and only a menu of the file manager was displayed. I could not reset unity by using unity --reset, because it stopped at a point.
I had to reinstall the whole system. System update by using live cd didn't solved the problem (desktop was still destroyed after this installation), therefore i had to remove the old system and to reinstall the whole system again. This is the second time that compiz manager destroyed my desktop. In ubuntu 11.04 i had the same problem for months ago.
My hardware is as follows:
Intel® Core™2 Duo CPU E8400 @ 3.00GHz × 2 motherboard P5K-E Wifi 8 GB RAM Ubuntu 11.10 x86_64
How can i avoid this problem in the future? Exist there an known bug with this hardware?
