I have the same issue on 9.10. Sometimes it is missing the gnome panel. When I restart it normally is back there, but the system will complain that "the gnome panel is not responding, are you sure you want to reboot?"
I would suspect this to be linked to compiz or 3d effects? -- taskbar icons corrupted after logging out and back in https://bugs.launchpad.net/bugs/469818 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
