after a fresh clean install of ubuntu (my old install got borked somehow) i cannot for the life of me get my games from steam to play when Xinerama is enabled, it worked with my last ubuntu install with absolutely no issues, now all that happens is every time i start a game all three screens go black and nothing shows except the cursor no sound no visuals nothing , here are my specs:
- Ubuntu 15.04
- Nvidia 970 using the 352.21 driver
- Intel i7 4790k
and here is my config

You'll have to enable Basemosaic in the Nvidia driver to get all monitors working together, when Xinerama is enabled.
