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?
I am pretty sure that such a user can do much larger harm than playing
with brigtness of my LCD. Anyway I went with my own rc.local hack.
Can he? Those are bugs to be fixed. We don't want them in kernel...
Pavel
