Earlier this evening my system's graphics hung, all I could see was a green screen. I reset and could not get to a login GUI and was presented with a black screen, however Ctrl-Alt-F* keys opened up new terminal sessions, so I tried reinstalling the NVIDIA drivers that I had. No joy.
Before this issue, I had 3 drivers installed:
However, 0 of them were active. By purging the NVIDIA drivers, I could get back to nouveau - however this is locked to a resolution of 640x480 on one monitor and there is no xorg.conf file to be found.
It seems that the NVIDIA drivers do not work on my system, as the graphics are completely gone, however up until now the system has managed to work with 3 drivers and 0 of them being active.
Are there any troubleshooting steps that I could take to increase the resolution and get both of the displays operating again? All answers that I could find resulted in ensuring that nouveau wasn't blacklisted and removing the xorg.conf file.
Ubuntu OS Version: 16.04
Edit: I should probably add that the version of nouveau that I have installed is listed as being compatible with arm64 architectures like so. I'm not sure if this is standard for the driver but I am currently running a 64bit Intel i5-3570k processor, which seems like it may be a potential root of the problem. Hopefully this helps.
Edit 2: Graphics card: NVIDIA GTX 670.
