I can't automate and automatically reduce display brightness on monitor external after 5m of inactivity on "settings" powermanager in Zorin OS 16.3.
Any control of brightness remotely can't work manually too
This basic function not work properly
This issue is correlate with driver video? I can fix it if I choice and install the driver graphic video correctly (see photo)?
Have you tried using the Nvidia 340 driver?
I tryed 1 times after this error and was install normally after close firefox. But don't work brightness too. I will try another OS. Thanks
