I got twin view running on my FC6 install (have latest drivers). It looks great (3200x1200)
The only problem i have is when i enable desktop effects. When they are enable they work fine, however when i play an avi in VLC and tell VLC to do full screen it does it across the 2 displays, something it doesn't do if desktop effects and enabled.
Now my question is, is this a VLC problem or something else???
