I'm using ubuntu 11.10 + gnome 3. Before I installed proprietary driver for my discrete card, Everything had worked fine (System indicator, Activities corner, dash,...). After installing the driver, the interface corrupted. Everything's gone except for a bar which contain: File, Edit, View, Help,.... and the desktop, I cannot use Alt+F2 nor windows button
Even when I uninstalled the driver, nothing's changed :'( I doubt that the proprietary driver hasn't been entirely removed or the system cannot switch to the old Integrated card. How can I get things back?
