No, I have a Radeon X300 card.

I'm using Xorg and Xinerama - two 19 inch monitors - one desktop.  The 
problem that I have is that the right screen won't display until the system 
goes to sleep.  So, when I first login, I change the setttings to get the 
system to go to sleep in one minute, wait one minute, then move the mouse. 
The right screen then works as long as I don't log out.  (Locking and 
unlocking the screen works just fine.)

But the problems you're having sound more driver related.  Was there a 
reason you chose the Linux driver instead of the native FBSD one?
