Awesome Doesn't Know My Brightness Ajustment Buttons

After installing Awesome (with no other GUI environments), the function keys on my laptop (for brightness especially), don't work like they do when I install KDE or GNOME. So far, the only method I've found to control brightness is commands like this: echo "10" > /sys/class/backlight/nv_backlight/brightness echo "20" > /sys/class/backlight/nv_backlight/brightness echo "30" > /sys/class/backlight/nv_backlight/brightness echo "40" > /sys/class/backlight/nv_backlight/brightness echo "50" > /sys/class/backlight/nv_backlight/brightness echo "60" > /sys/class/backlight/nv_backlight/brightness echo "70" > /sys/class/backlight/nv_backlight/brightness echo "80" > /sys/class/backlight/nv_backlight/brightness echo "90" > /sys/class/backlight/nv_backlight/brightness echo "100" > /sys/class/backlight/nv_backlight/brightness However, I cannot easily automate these commands to hot-keys because they only work as root. Surprisingly, sudo doesn't even work when using my regular user account. For example, this doesn't work: sudo echo "60" > /sys/class/backlight/nv_backlight/brightness The above command outputs: Permission denied. So, as is, to change brightness I have to su first. Perhaps someone can explain how I can permit my regular user account to modify that path without escalation. Then, I'd be able to tie hotkeys to these brightness adjustments. Ideally, though, I suspect that there is a package I can install that would map my laptop's existing keys for brightness adjustment. Here's the model (if that helps you know the package): Machine: Type: Laptop System: System76 product: Bonobo WS v: bonw13 Mobo: System76 model: Bonobo WS v: bonw13
