As stated in bug #1162526 I can't switch to the discrete GPU as I could on 12.10. Using the workaround posted by Vangel Ajanovski in askubuntu (http://askubuntu.com/questions/142506/hybrid-graphics-on- ubuntu-12-04-switching-to-discrete) I can switch to the discrete graphics, but when I do the laptop backlight turns off and I can't turn it on by any method I tried. It does work with an external HDMI display.
