I am using the GNOME Shell interface on Ubuntu 11.10. The black titlebar with Activities, Calender, and the notification icons has disappeared. The Nautilus menu (File, Edit, View, ect.) is at the top instead. If I open any applications, they are missing their titlebar and the buttons, and appear in the top left of the screen. Does anyone know how to fix this? I am using a VGA graphics card, with no driver.
The output of lspci | grep VEGA
is:
00:02.0 VGA compatible controller: Intel Corporation 82915G/GV/910GL Integrated Graphics Controller (rev 04)
The output of /usr/lib/nux/unity_support_test -p

The Gnome Shell menu was crashing because of the alternate status menu extension I installed. This bug can be fixed by adding a picture to your profile.
I'm not an expert at all. But I just had a similar problem while I was tweaking things in compiz-config-settings-manager. So I opened compiz from the terminal by running: ccsm And then I clicked on on "Ubuntu Unity Plugin" to activate it. After reboot, everything was back to normal.
Hope it helps.
