I'm using 11.04 with Ubuntu Classic.
I can not ALT+Tab anymore, or use any of the Super shortcuts.
I did not upgrade. I used clean install.
I can't use any Super key shortcuts either. In 10.10 I could use Super + A to show all windows, it was really handy, now I can't.
I have Compiz enabled and everything, along with the advanced config program. Where do I go to enable these features (if they are even in Natty at all?)
I have Expose and Desktop Wall module of Compiz enabled, by the way.
Strangely enough, it does work in Unity now, I don't know why. It does not work in Ubuntu Classic.
