I have dual screen monitor setup.
There are applications (like VLC), where everything works out of the box. If you fullscreen a video, you can use your other screen normally. This is the setup I would expect.
Then there are mostly Linux games and ones you can run via Wine. If you run a fullscreen game, other screen just turns black, violet or flickers like crazy. Moreover, when you exit the game, the second screen is off, so I have to restart X.
Does anyone know how I make this work better? Is this just a matter of those applications not using the appropriate library, or are there more fundamental issues with mutli-monitor support right now?
Added later: Apparently there is no solution, Xorg is just fundamentally broken:
