I installed ubuntu 18.04 on my dell XPS laptop but for some reason the screen brightness buttons don't work.
My laptop model is XPS 15 7590 with a NVIDIA(R) GeForce(R) GTX 1650 4GB GDDR5 video card.
I have found a solution by executing the "xrandr --output eDP -1 --brightness ". But this is a bit too hacky for me and not practical.
Does anyone have any workarounds for this?
Thanks -N
