How do I make my HP G62 function keys work?

Question

I've just installed Ubuntu 11.10 (but this problem also appears at 11.04), on my HP g62 laptop, and unfortunately none of the function keys work.

Volume, brightness etc, how can I made them work under Ubuntu?

Answer 1

Fn Brightness Keys - Workaround

Currently it is impossible to map the FN keys. Therefore, two utilities for mapping alternative keys are needed so that screen brightness can be adjusted. From terminal:

sudo apt-get install xbacklight

Download Ubuntu Tweak from here and install it. Now open Ubuntu Tweak (Application -> System tools) go to the appropriate section (Personal -> Shortcut) and set the combination that you want for example

Ctrl+Up

xbacklight -inc 10

Ctrl+Down

xbacklight -dec 10

To increase and decrease the screen's brightness
