I can confirm the behaviour with slow refreshes for some 60-90 sec in my case. Disabling Compiz got Karmic up and running again.
To be able to activate Compiz again I first had to supress autostart of Awn. Temporary solution: sudo mv ~/.config/autostart/awn.desktop ~/.config/autostart/awn.desktop.backup Thus Compiz and Awn do not seem to work together after some updates done recently. -- [karmic] latest updates causes compiz to slow to a crawl https://bugs.launchpad.net/bugs/395543 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
