Jul 21, 2013 at 20:32 comment added Joseph R. Interesting tool. I will give it a go. What I actually meant is: how come the regular user is allowed to change backlighting through (for example) a keyboard button but not through the command line?
Jul 21, 2013 at 13:40 comment added slm @JosephR. - see updates to my answer, shows how to use it.

Jul 21, 2013 at 13:32 comment added slm @JosephR. you can use xbacklight to expose this capability to userspace.
Jul 21, 2013 at 7:55 comment added Joseph R. @slm Do you happen to know if there's a wrapper/helper tool that lets you control brightness as a regular user?

Jul 20, 2013 at 20:08 comment added slm @KioMarv - is there anything under /sys/class/backlight?
Jul 20, 2013 at 19:57 comment added Kio Marv Hi! When trying the first line I got: bash: /sys/class/backlight/acpi_video0/brightness: No such file or directory. Inside /sys/class/backlight there is only a link named toshiba that points to ../../devices/LNXSYSTM:00/LNXSYBUS:00/TOS1900:00/backlight/toshiba/
