Hey guys. I have tried a few different things for solving this problem to no avail. I'm hoping someone can help.

I am running Ubuntu 12.04 an asus p8h61-m le motherboard with an i3 processsor, 4gb of Ram, and an ati hd 5450 graphics card. This is all plugged into an Envision 19" monitor, and my Insignia 43" HDTV. I have Steam and Half life 2 installed in the same virtual drive, using the latest 1.5.5 version of Wine. 

Here is my problem: When I try to run Half life 2, (or any other steam game for that matter) My screen goes black, says no signal and goes into standby mode. What happens, is it switches from duplicating my monitor on my tv to only displaying on my television. 

I quit out of the game and tried to switch back to my monitor, using both ARandR, and Catalyst Control Center. Lo and behold, Ubuntu thinks my monitor is unplugged. I can fix this by either logging out or restarting, but it is a pain in the butt.

If anyone can help with this problem, it would be greatly appreciated. I have every extra package installed that should be needed, and probably a few that aren't. I have also tried using crossover games, but came back to this because I can't pay $60 for the software.

Thanks,
