I've installed a pre-made Ubuntu 10.04 image at work, and I can't seem to figure out how to get desktop switching to work. No shortcuts work, and all the help I can get from the Ubuntu forums is "CTRL-Alt-Left/Right should work."

So let me get this straight. Switching between desktops is deprecated, so we use viewports, which are managed by Compiz, which has one of the most absurd configuration managers out there. Lovely.

Can anyone straighten this out for me, and anyone else who might stumble on this question?
