Has anyone been able to get Serious Sam 3 to run using Xinerama on an nvidia setup? It's my understanding from googling that this is not possible, and try as I might I have been unable to disable the option using nvidia-settings, nvidia-xconfig or manually editing xorg.conf.
After starting the game, a black screen appears, then just before where there should be information about the display the user is using the game dies. Here's the full log and my xorg.conf. I'm running 64-bit arch linux with an nvidia 9800GT card.
If I physically unplug a monitor, and attempt to start the game, the same problem exists.
When starting nvidia-settings I see this dumped to the output:
Xlib: extension "RANDR" missing on display ":0.0".
I thought I'd add that in case it was relevant, but it's also my understanding that fixing that problem is not currently possible (this problem 'apparently' only occurs when using Xinerama, though as I have not be able to disable it, I cannot confirm this).
