So yesterday I booted up my Ubuntu and found that the screen is stuck at a resolution of 640x480. How it came to this I don't know, I haven't changed anything other than updating the system.
The settings come up empty; it doesn't show any resolution at all, just an empty box. I have tried to re-install the nvidia-390 driver (graphics card is Nvidia Geforce GTX 750 Ti) and to manually build it into the kernel, but to no avail. Nothing I do has worked. Please help, this is tiring quickly and I need my pc.
Extra info: it seems that monitor "1" is in use instead of monitor "0" (echo $DISPLAY results in :1).
