Trying to install Ubuntu 13. I get the CD boot screen fine. Select Install and hit Enter and the screen goes black. I originally thought the install was stalling out but under my bright desk light I noticed the install window. So I cranked up the LED on my phone and can see the install windows. I've tried all sorts of key combinations but cannot get the backlight for the screen to turn on.
Anyone run into this before?
Ubuntu 13.04 64b (Haven't tried with 12 but downloading it now.)
