I have a laptop Assus TUF A17 FA706IU-H7101, nvidia card Ubuntu 20.04 installed. In additional drivers nvidia-driver-440 selected.
All looks good aside i cannot change the screen dim levels. If i use dim keys or the settings menu there is no change.
Also the nvidia settings app opens but has no widgets in it: nvidia-settings ERROR: An internal driver error occurred ERROR: Unable to load info from any available system
Output of xrandr: 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*
I already looked everywhere for a solution, no luck so far. This is really annoying as i cant work/look for more then an hour in the laptop because of the brightness.
Anyone has a workaround for this ?
