Having trouble installing a piece of hardware? Want to know if that peripheral is compatible with Linux?

Keyboard Lighting


No help on Ubuntu or mint so am trying here. It's frustrating constantly having to hit F10 to turn off keyboard lighting to save power.

Mint used to have an entry under system.d that in effect would deny keyboard lighting. It is no longer there so I was wondering if i could insert the file into system.d. I have a copy of the file which went something like this "<deny send_destination="org.freedesktop.UPower"send_inte rface="org.freedesktop.UPower.KbdBacklight"/>". This would cancel my keyboard lighting unless I wanted it. I have a Dell lapiron and the F10 key will turn it off and on. Without this entry the keyboard lighting keeps turning on.
So like I said could I insert that file into system.d somehow without causing a problem?
TIA

You should be able to control this somewhere in /sys/class/leds/"yourleddevice"
And you could probably make a simple shell file to automate the process (on boot) by running sh keylight.sh
Something like
Code:
echo 0 > max_brightness
Here are some fairly distro agnostic ways to look at the issue and deal with it in a few different ways:

Thanks ever so much for your help; looks like there will be a solution in there.

P.S. I used to edit this line to "deny" in /etc/dbus-1/system.d/org.freedesktop.UPower.conf. Thanks to you I discovered the line moved to:
/usr/share/dbus-1/system.d/org.freedesktop.UPower.conf
