Hi, I have just learned that my Xfce Power Manager cannot manipulate brightness because I do not have policykit installed on my computer. There is a reason for that (yeah it depends on systemd which I prefer not have). While this is clearly a problem of the Xfce applet I am wondering why setting the brightness has to be a privileged operation at all. Is there any strong reason for it or just a general policy that we do not give world writable files into sysfs?
Well, if you have another user logged in using ssh, and changing _your_ brightness, that will be somehow annoying, right? That's the reason why global settings should be root-only...
