Running slstatus as root is no real option - however there are not that
much alternatives to reading from /dev/ttyC0. Linking against xcb-xrandr
is bloated and appearently doesn't work for every setup.
A possible workaround would be to set the group permissions of
/dev/ttyC0 in /etc/rc.local or crontab automatically - which is not
perfect.
The question that comes up to my mind is: Do we need the backlight
component? I can literally "see" the current brightness of my screen.
Tell me what you think and we will come up with a sane solution.
Cheers!
Aaron
