No answer yet, my understand is that:

1. xfpm-power-backlight-helper need to run with 'pkexec'.
2. 'pkexec' will always ask for password unless some polkit rules allow
   the action.
3. '/etc/polkit-1/actions/org.xfce.power.policy' allows the action, but its
   executable is something like
   
'/gnu/store/vsnzjhjm37cd42w7vv7mxgy8hi8w6zi0-xfce4-power-manager-4.16.0/sbin/xfpm-power-backlight-helper'.
   
So run 'pkexec xfpm-power-backlight-helper' will ask for password while 'pkexec 
/gnu/store/.../xfpm-power-backlight-helper' will not.
