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?!?

Re: How to adjust brightness of the screen?
Not sure about MATE but looking in System Settings (or similar) I seen to recall something about Power Management. Just wondered if an auto dimming box might be ticked which is interfering with your ability to adjust? Sorry its vague, I don't use MATE!

Re: How to adjust brightness of the screen?
I got it to work! After the last fix it's working but only bith the function keys, not from the terminal! That's good enough!
