Hey everyone! I own a CF-19 that previously just had Windows 7 installed.

I want to try out Linux, specifically Ubuntu since it seems to have the most support.

When I installed Ubuntu 20.40 LTS everything seems to work expect a few items.

At first the sound did not work, but after some searching I was able to find a fix.

Next the brightness adjustment does not work. When using the keyboard or settings to adjust the brightness slider the brightness level of the screen does not change. The slider does move, but the screen itself never changes brightness.

Any thoughts on how to fix this issue?
