Excerpts from Alexey Feigin's message of Thu Oct 15 00:07:46 -0600 2009:

There are two sections in the FAQ on the wiki that might help:

I would start with the Configuration/Multi-head & Workspaces one, to see
if mod-w mod-e, mod-shift-e, etc., and workspace switching works as it's
supposed to. If not then you could go to the Multi-head troubleshooting part
to make sure your haskell x11 was compiled with xinerama support, but I
suspect that your haskell setup is okay, from what you describe.

If default xmonad screen and workspace handling isn't working correctly I'd
suspect your multi-head is actually not in a xinerama configuration but
rather using separate X displays. Unfortunately I know nothing about ATI
xinerama configuration, hopefully others can step in if that does turn out
to be the problem.
