** Tags removed: 16.04 4.4.0-34 display kernel needs-bisect
** Tags added: kernel-fixed-upstream-4.4.19 needs-reverse-bisect
regression-update
** Changed in: linux (Ubuntu)
Status: Confirmed => Incomplete
** Description changed:
As per reported by several users, such as in
https://ubuntuforums.org/showthread.php?t=2333398, apps that control
screen gamma, such as Redshift/Flux/brightness-controller, stopped
working under the newest kernel 4.4.0-34 in Ubuntu 16.04 LTS, and we're
not sure what caused the issue.
Those apps are still working well on external monitors. It's just the
internal monitor that is not responsive. Any setting just simply has no
effect.
It seems that all the users are using Skylake-based laptop.
In my case, my laptop is on Skylake and GTX980M.
