I'm running openSUSE 11.2 (desktop
here) on my laptop and LOVING it! I've got the 4 virtual desktops set up in a 2x2 grid, and I can switch between them just by moving the mouse to the side of the screen, so it like leaves one screen on the left and enters the next one the right. I can post screenshots if you want
And yes, I can do the rotating cube thing also...
