Title:
Ubuntu 14.04 on Acer TravelMate P253: LCD screen brightness always at
maximum level
Status in “linux” package in Ubuntu:
Expired
Bug description:
Hi,
on my new Acer TravelMate P253 notebook, with ubuntu 14.04 desktop I can't
modify LCD screen brghtness: by pressing the normal key combination for this
function (Fn+Left / Fn+Right) the screen brightness applet correctly shows up
on the screen, and its level correctly goes up and down when pressing the
function keys, but nothing actually happens, and the screen alway stays at its
maximum brightness.
Thank you, your suggestions are always welcome.
Adalberto
