Function key+ arrows is not working (mint 14 mate on acer 3820tg, the brightness bar is actually moving back and forth, but it's not changing the brightness), so I tried to make a search and I tried the following without success:
Installing Xbacklight and
xbacklight -inc 40
changing from power management
sudo setpci -s 00:02.0 F4.b=99
None of them is working for me. What should I do?!?
