[Bug 1472897] Re: cannot adjust brightness E6530 15.04 fresh install
After hunting for solutions for hours, I have given up and installed
bumblebee. Suggested troubleshooting steps have a higher chance of being
attempted if instruction is given on how to switch X to reroute through
the nouveau driver (a way to toggle between bumblebee and nouveau).

Title:
cannot adjust brightness E6530 15.04 fresh install
Status in xserver-xorg-video-nouveau package in Ubuntu:
New
Bug description:
Press Fn + up/down arrow.
Expected to happen: brightness goes up or down; notification in top
right of brightness going up or down.
Actually happened: brightness stays unaffected; notification does
appear and respond correctly, but lies.
Cannot adjust brightness using function key combo. Shows the
notification as if I am adjusting it, but screen stays on max
brightness. Brightness & Lock app doesn't adjust brightness either.
When I switch to proprietary drivers, brightness adjustment does work.
When I turn off the nvidia card and use the intel card, brightness
adjustment works. But with the intel card only I don't have hdmi port
support, so no triple monitor support. And with the proprietary
drivers, I get horrible, horrible bugs, including one that made it
impossible to get into my system until I modified bios settings
related to the video card.
