I've installed Ubuntu 11.04 recently, and almost everythings works fine. Except when I try to use multi-monitor. The new monitor is recognized, and even show the title bar, but don't show any thing else.
I though that maybe it could be because unity is still under development, but i saw another post (right here) where people say that they hadn't have my problem.
I'm running Ubuntu in a HP G42 Notebook.
Any ideas will help me.
