I have a 2-3 year old gateway laptop that I wiped the hard drive to. I tried installing Ubuntu 13.04 from a DVD and that didn't work, but that isn't the question I'm asking. I am now trying to install Ubuntu 13.04 from a live pendrive I created using the Universal USB Installer. It loads everything just fine, but when it loads the home screen, it is so dark, I cannot see well enough to navigate. Is there an Ubuntu-specific key combination to turn up the screen brightness or anything else I should try?

Edit - I tried using the fn + up/down arrow keys for brightness and they did not work.

  • Did you use xbacklight? – Danatela Jul 30 '13 at 3:13
  • I have no idea what that is, but I did manage to fix the problem by hooking my laptop to my TV then navigating to the brightness settings – Pomg Jul 30 '13 at 14:39

Usually all the laptops today have a "Fn" or a function key, which can be used in combination with another key to control screen brightness.

I haven't used a gateway ever before but i assume there must be one of those keys in the top row which has a brightness icon.

Fn + Up(Arrow Key) would be my best guess.

Or Fn + Brightness Up key

Some examples of brightness keys: enter image description here

Hope that helps you.

  • I tried using that and it didn't work. Is it supposed to? – Pomg Jul 30 '13 at 1:42
  • Hi @Pomg , Yes they are supposed to work. I would also try hunting for gateway drivers for linux for these special keys. – Dexobox Jul 31 '13 at 3:08
  • The keys seemed to work after I actually installed the operating system. When I ran it off of a live thumb drive, they didn't work, but once I hooked it up to a TV, I was able to see what I was doing well enough to install Ubuntu onto my computer, from there I was finally able to use the Fn + Up/Down arrow keys to control brightness. – Pomg Jul 31 '13 at 14:19
