I have Asus ul20A and what I think is the newest netbook version of Ubuntu, and I can't seem to find a way to change my screen's brightness. It's a shame, because it takes hours off my battery life.
Googling offered an answer: Upgrade my BIOS to 210. The thing is, my computer doesn't have a CD slot. So How can I upgrade my BIOS, or is there another way to change my screen brightness?
I have already tried tweaking lines in grub and xbacklight, so they do nothing.
