[ubuntu] gnome or ati catalyst problem?

view story

http://ubuntuforums.org – I was messing around in ATI Catalyst with an external display and somehow caused this desktop problem (see bmp attached) note the multiple icons along the top and weirdness along the bottom. I tried removing my .gnome profile but no use. Is this something related to ATI Catalyst or gnome? Any ideas on getting the desktop back?
