I'm using xfce with arch linux on an Asus Zenbook Prime (UX21A) and noticed that by upgrading from xfce4-power-manager-1.2.0-3-x86_64 to
xfce4-power-manager-1.2.0-4-x86_64 a faulty setting is introduced: whenever the screen returns from a blankd out state the program xfpm-power-backlight-helper sets screen backlight to max; here is the journalctl output:
archlinux pkexec:: Executing command [USER=root] [TTY=unknown] [CWD=/] [COMMAND=/usr/bin/xfpm-power-backlight-helper --set-brightness 10]
This is annoying because you have to readjust backlight every time manually.
Can anyone shed some light on this? Where can I configure these settings?
