I upgraded from 10.10 to 11.04 through Update, and after a while the Compiz crashed with the title bar and most of the windows acting up and so on, ending up with nothing else doable but reboot.
After reboot it says, that there's some errors, and I've reboot in the fix-mode, and it wrote/noted something like "deleted compizconfig-1 INODE detected". After a while, it checks over all the file(system) and fixes and such. After the next time it happens, I can update here with some more errors.
The question is, that is there a fix, or do I really have to downgrade back to 10.10 or change out the compiz?
Note: I've got Intel G915 graphics, 2GB of memory, Dell Latitude D410 laptop in short.
