I installed Ubuntu 11.10 yesterday, and have been struggling with enabling desktop effects for hours. I downloaded the CompizConfig Settings Manager, and tried selecting-deselcting various items. But they don't seem to be taking effect. Please help. Thanks.

VGA: 00:02.0 VGA compatible controller: Intel Corporation 82946GZ/GL Integrated Graphics Controller (rev 02)

EDIT:

New problem! I made a few changes in CompizConfig settings, and a few effects started working. Like wobbly windows, and rotating cube.

Then I tried enabling a few application switchers, and it asked me to resolve the conflicts. I guess one of them was "enable OpenGL".

As I clicked it, everything crashed. Dock vanished. I only a see one bar at top with menus File, Edit, .., Bookmarks, Help.

I am not able to access anything else. [Alt] + [F2] and [Super], both are not working. What do I do? Please help! (Right now I am accessing web via a guest account. To get any work done, I have to be able to use my own account again.)
