When I installed Ubuntu 11.10 Beta 2, during live-CD install, I tried out the new application switcher and it worked beautifully. After the installation is complete, the new application switcher is gone. In its place is a ugly grey Windows XP-ish thing.
I am not sure if this is a graphics driver issue, because I enabled nvidia proprietary driver. But other 3D related things looks fine. So how can I get the new application switcher back?
