Suddenly my HDMI 2nd monitor stopped being detected today, and VGA 1st monitor is stuck at 640 X 480

It has been like this since the day after I installed PoL and a Game.

I am hoping to find a solution to this very annoying issue. I turned on my PC today and noticed that only my VGA monitor was detected, which is odd because just last night both monitors were working normal. The other issue is that the monitor that does work will only allow me to have 640 X 480 resolution.

Things I have tried:

  • Switching from Nvidia drivers to Xorg.

  • Purging and reinstalling Nvidia

  • Rebooting several times

  • Adding monitors in the terminal with Xrandr (When I do this it gives me "Failed to get size of gamma for output defaults")

  • Trying other HDMI cables.

  • Booting from an Ubuntu DVD. The monitors worked normally here.

Yesterday I was tinkering around a bit with Wine and PlayOnLinux, but I am not sure if that is what caused this issue. When I go to the monitor settings it only shows my VGA monitor, and will not let me change the resolution. I was originally allowed to change the resolutions of the HDMI and VGA monitors with no problem. 

This problem only has existed since the initial reboot after installing PoL.

Let me know what other information I can provide to help fix this issue.

 

After entering lspci -v | grep -i nvidia I get:

01:00.0 VGA compatible controller: NVIDIA Corporation GK107 [GeForce GT 640] (rev a1) (prog-if 00 [VGA controller]) Kernel driver in use: nvidia Kernel modules: nvidiafb, nouveau, nvidia_384_drm, nvidia_384 01:00.1 Audio device: NVIDIA Corporation GK107 HDMI Audio Controller (rev a1)

Definitely sounds like a driver problem.

Are you able to rollback to an earlier Nvidia driver?

I haven't upgraded to 387 yet, so maybe try the newest driver too...

What Distro are you using?
