I have two monitors (the built-in 1680x1050 of the portable's LCD and an
external Acer AL2216W at 1680x1050). The command

aticonfig --initial=dual-head --screen-layout=right

produces a correct display, but I can't move windows between monitors.
:-( I've tried the directions for big desktop without success.

Is there an easy way to do this?
