brightnesskeyboard shortcutsopenbox
I'm using Openbox window manager without DE.
I'd like to get fn + [brightness up/down icon] working like it is in GNOME/KDE, but I’m looking for a lightweight solution without gnome-power-manager and similar.
I know about the xbacklight console program, but it takes a little time to adjust brightness.
There's probably hundreds of equally valid answers for this, but I use gmrun:
It has miscellaneous useful features:
You can run a command in a terminal using Ctrl+Enter
It keeps a history of commands, so you can just keep hitting Up to cycle through them, or search through them with the standard shell mechanisms, Ctrl+R and !.
It also has Tab-completion:
It will let you run a file directly (it knows what program to execute for that particular file type):
Don't know how to fix it, but do know how to work around making the screen worse when fixing it. Maybe the following will provide some clues as to how to find the culprit.
Here's my script for getting/setting the backlight value.
I also use KDE and have a slightly less annoying problem. Every time I come back from screensaver/screen off, the display is at brightness 1 (the lowest) which is not what I want.
I wrote the script, copied it into /usr/bin and added an icon to my taskbar to launch it. I use it multiple times a day. The command the icon runs is
kdesudo -- /usr/bin/backlight 5
and I added the line
bigbird ALL=NOPASSWD: /usr/bin/backlight
to /etc/sudoers so it doesn't ask for a password.

I don't know how to do it, but if you can watch for who changes the "field" in /proc, maybe you'll be a step closer to finding the culprit.

I use
Or values other than "5".
