powersaved daemon decrese my display brightness

At boot, before login, when powersaved daemon is started, it decreases my brightness on half.

I went to /etc/sysconfig/powersave and in both scheme_performance and scheme_powersave, I set DISPLAY_BRIGHTNESS to “max”.

That didn’t help.
How do I prevent bootup to decrease my brightness?
