Public bug reported:
For my HP tablet tm2, I always has this issue with every version of
ubuntu. My screen brightness never changes even after pressing the
keyboard shortcuts. Even the brightness slider on panel doesn't work. It
displays the brightness slider decrease/increase but it doesn't affect.
Still remains the same.
