Yep. Fiddle with teh xorg config a little (try commenting out the
line that reads something like 'screen0 leftof screen1', and
ctrl-alt-del your x-server. for me, it fires up the 2nd head,
though cloned. unedit the xorg.conf again, ctrl-alt-del,
and it behaves as you would expect.
spooky bug, and been there since fc1.
