[Bug 1381625] Re: Adjust brightness to lowest value caused screen whole black
Ok, so this got fixed for i915_bdw in
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1374389
but even the fixed kernel doesn't work on my Wilson Beach SDP, and the
commits in i915_bdw got reverted for 3.17 and up. Even drm-intel-next
(->4.1) doesn't work.
So I guess it's best to fix in userspace until the driver side is fixed
once and for all..
