Bug#699730: gnome-control-center: brightness resets on reboot or logout

[Zack]

Package: gnome-control-center
Version: 1:3.4.3.1-2
Severity: important
Tags: upstream

Dear Maintainer,

I went into system settings/gnome-control-centre, and set the brightness to
minimum. However, when I reboot, or log out, it reverts to maximum brightness.
This also happens sometimes over long periods when I haven't logged out, for
example when I leave it long enough to suspend (although not when I suspend
it). I have searched the web for similar bugs and believe it to be a gnome bug.
It may be related to another similar bug, in which the brightness short-cut,
fn-down, on my keyboard only reduces the brightness about a fifth of the way to
minimum.

My screen is painfully bright on maximum, so I couldn't just ignore this bug,
and having to manually reset it every time it happens is annoying.
I could not find any way of stopping that happening,
https://extensions.gnome.org/extension/231/brightness-control/ this extention
did not reduce brightness at all, I presume because the bug affects this. I
found a work around which is an executable (I will attach it), which sets
the brightness to minimum, which I can set to run up start up and then as a
short-cut for whenever it resets to maximum.

What I expected is that I would have to set the screen brightness within
settings and it would stay at that brightness indefinitely and across reboots,
and I would only need to re-adjust it when I want to increase the brightness.
