Re: XPS 13 brightness has completely stopped working
I am trying almost everything except going back to old Windows (now I have W10 pro 1809). Nothing works.
If I reinstall the chipset driver, it works again untill... something that I don't know that again make the brightness controls useless.
Video driver is 22.214.171.12473 28/feb/2018
By the way: I have also an XPS15 9550 that has the same Win version and it has no problem.
