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.
