I have Ubuntu 22.04 with
$ lspci | grep VG 08:00.0 VGA compatible controller: NVIDIA Corporation GK208B [GeForce GT 730] (rev a1)
Today the resolution of the display was forced to 1024x728 (refresh rate 76 Hz) with no options. I am getting the error
xrandr: Failed to get size of gamma for output default, so I tried the solutions of these posts (1), (2), (3). But nothing has changed.
How can I force a resolution of 1920 x 1080? Or let the system recognize the display automatically as before?
