Re: Dual NVIDIA GPUS with NVIDIA driver not working

Where does your xorg.conf come from?

No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan

Re: Dual NVIDIA GPUS with NVIDIA driver not working

Does the "nvidia-settings" tool help?

Re: Dual NVIDIA GPUS with NVIDIA driver not working

Post xorg logfile please.

Temporarily remove/rename that xorg.conf file, post xorg log from booting that also.

Re: Dual NVIDIA GPUS with NVIDIA driver not working

Unless you're willing to run 2 X11 servers, you'll have to use https://wiki.archlinux.org/index.php/NVIDIA#Base_Mosaic (assuming SLI isn't available)
This is guaranteed to work w/ equal GPU types, idk. whether it'll work with the slightly different chips.
