[Solved]Issue with Xorg (4 Monitors, Dual GPUs)

Hi there,

I have been an Arch user for about 4 months (Ubuntu for a year, before) and I was running Awesome, until yesterday.

I just upgraded my Workstation and decided to try BSPWM.
So far, so good. Install was pretty straightforward but I am having an issue with the graphics.

I am running two similar graphic cards: Nvidia

   02:00.0 VGA compatible controller: NVIDIA Corporation GF119 [GeForce GT 610] (rev a1)
    03:00.0 VGA compatible controller: NVIDIA Corporation GF119 [GeForce GT 610] (rev a1)  

And I have 4 monitors, but I can't have all of them running. Only two at a time.

xrandr -q output:

    Screen 0: minimum 8 x 8, current 3840 x 1080, maximum 16384 x 16384

The two other monitors are on, but they're blank.
I can hover my mouse over them, but can't "control" them as I am unable to open a terminal window in them, etc.

Do you guys have a possible solution?

Thanks!

Hi,

Fixed it.

Used nvidia-settings to automatically update my xorg.conf file.
