Hiya.
fglrx drivers wont allow you to use ALT + TAB (or CTRL + ALT + Left / Right) when a program is running in full screen mode (openGL) it always stays on the front.
It is actually switching, but the program is always on top.
Easiest way to test is to install fglrx and then run
glxgears -fullscreen

Hey VixsLee,
Hi, have you had a chance to test if this bug is still present in natty?
If it does (and if you're the original reporter), please boot into natty
and run the command:
apport-collect <bug-number>
which will update the bug with fresh logs and tag the bug as affecting
natty. (It is best to run this right after reproducing the problem.)
