Vlad Zagorodniy 0d381846f1 Backport Night Color feature to X11
Summary:
The color correction manager doesn't make any specific assumptions about
underlying platform, e.g. whether it's x11, etc. The platform just
has to be capable of setting gamma ramps. Given that, there are no any
significant technical blockers for making this feature work on x.
