I encountered a similar problem with my Ubuntu computer locking up. I had previously been using Ubuntu 8.10 and I think I had Effects disable, but I had to do a fresh install of 9.10 because I could not get 9.04 to work on my computer. When I upgraded to 9.04 the system would freeze up also including while Update Manager was running which made the system unbootable.
In any case, based on the comments posted here, I have removed all packages with compiz in the name. The system now seems to be running fine. I don't think I've ever used the Desktop Effects so I'm not missing anything. My computer has an ATI Radeon X1300 (RV515). -- Gnome Freezes -- Ubuntu 9.10 -- big time freezes. https://bugs.launchpad.net/bugs/461163 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
