["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

jtryon, thank you for reporting this and helping make Ubuntu better.
Could you please test http://people.canonical.com/~kamal/lp1169376/ and
advise if this issue is resolved?

** Description changed:

- I can just barely make out the screen, this seems to be related to:
- https://bugs.launchpad.net/dell-sputnik/+bug/1169376
+ I can just barely make out the screen in fresh 14.04 install.
  
- ...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.
+ WORKAROUND: Boot with Legacy mode enabled in BIOS.
