Public bug reported:

I can just barely make out the screen, this seems to be related to:
https://bugs.launchpad.net/dell-sputnik/+bug/1169376

...though I'm running a fresh 14.04 install.

What I discovered is that I have regular backlight operation if I boot with the BIOS option for "Legacy" boot options.
When booting with Legacy off I get the brightness issue.

I don't necessarily want the legacy options on since they take
precendence over the UEFI ones for some reason.
