** 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.
