Description Martin Klapetek 2015-12-22 14:41:46 UTC 
I very often use custom brigthness levels depending on where
I am. So eg. if I'm at some place that has low ambient light and
I'm on AC, I turn the brightness down to ~50%.

But everytime I reboot/relogin, the brightness is brought back
to the preconfigured level, making me blind for couple seconds.

So I'd like to propose to (have an option?) remember the brigthness
levels between sessions. I think it could simply store AC state and
brigthness level and on new session login check for the AC state
being the same and if yes, then restore the brightness level.

Or maybe just don't set any initial brigthness value on systemd
systems, where the systemd-backlight already does that, it just
gets overridden by powerdevil on its loading.

Then just uncheck the brightness setting?

Right, just uncheck the "Screen Brightness" setting, and then powerdevil won't mess with your brightness level at all.
