I'm on Ubuntu 20.04 and after an upgrade, my resolution was reset on reboot. I went from a 1920x1080 resolution to a 800x600.
I normally use arandr to adjust my resolution, but now I only have the 800x600 option.
My output was named VGA
or something similar. Now it's called default
.
When I enter the command xrandr -q
, I got this:
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 800 x 600, current 800 x 600, maximum 800 x 600
default connected 800x600+0+0 0mm x 0mm
800x600 75.00*
Can someone help me to fix this urgently, please ? This is almost impossible to work like this.
By the way, I already tried these: Failed to get size of gamma for output default when trying to add new screen resolution and https://stackoverflow.com/questions/47391669/xrandr-displaying-failed-to-get-size-of-gamma-for-output-default without any success.
When I enter this lspci | grep VGA
, I got this output:
01:00.0 VGA compatible controller: NVIDIA Corporation GK208B [GeForce GT 730] (rev a1)
I don't really know if this is important, but I saw people giving their GPU specs on several posts.
