Kubuntu 18.04 terrible resolution and lags after crash
My computer under Kubuntu 18.04, with an Nvidia GeForce GT 630 (probably 6 years old), was working smoothly until I decided yesterday to play World of Warcraft TBC with Wine. I could play for a while until the computer completely froze. I forcefully rebooted it (Alt+SysRq+B) and after that, the computer became much slower and the display smaller than the screen. I first thought that it was just a resolution change but realized that I couldn't manage to change the resolution.
By going through several forums, I realized that the monitor may not be recognized properly, as the command xrandr returns:
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1920 x 1080, current 1920 x 1080, maximum 1920 x 1080
default connected primary 1920x1080+0+0 0mm x 0mm
1920x1080 77.00*
Several suggestions were made for similar issues on different forums, most of the time including modifications of the /etc/X11/xorg.conf file which I couldn't find.
I'm using the default Nouveau driver and tried using the recommended driver nvidia-driver-390 (and rebooting). But nothing allowed me to improve the display.
I have to admit that I am pretty confused that such thing could occur after a simple crash. Now I can't even display properly any youtube video (which would look more like a 5fps video montage). I have been struggling a lot with Kubuntu and Nvidia drivers previously, with bugs such as flickering screens appearing after trying all the different drivers, and always solved them by reinstalling the whole setup. But this time, I've been working on and customizing my setup for a long time and therefore would like to take the bull by the horns and solve the monitor detection / driver issue rather than just formatting everything again.
Any suggestions or hints on how to solve my issue?
