I had the same problem. The first workaround was to add a startup command: compiz --replace
But then I read that some gnome- or compiz-settings could mess up compiz. I was able to narrow it down to the file ~/.local/share/applications/compiz.desktop So I simply removed compiz.desktop, since it is not really needed anyway. And after that compiz runs normally. I removed the workaround with the added startup command ofcourse. -- windows decorator won't start https://bugs.launchpad.net/bugs/438925 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
