Hello i have a sony vaio vpcf236fm. I am unable to disable or control my keyboard backlight. i want to be able to disable it when im running on the battery. Please if i could get help with this id be in your debt.
Run this command and tell us if it turns it off:
You will have to type in your password to try it. To open up a terminal, just type Ctrl-Alt-T or open it from the Unity menu.
I'm just going to go ahead and assume this command works and show a nice little script that will automagically turn the keyboard backlight on and off when you unplug the battery. If the command doesn't work....well the script'll be here for future reference then.
Run the command
Then paste the following into the
Then run this command:
You may need to restart your computer for this to take effect. Theoretically, this should turn your keyboard backlight on and off when you plug and unplug your charger.

EDIT: This may be a more "proper" answer: Keyboard backlighting not working on a Vaio VPCSB11FX
I do a different way, with this script:
#!/bin/bash FILE="/sys/devices/platform/sony-laptop/kbd_backlight" MODE=$1 if [ -z $MODE ] then notify-send -t 8000 "No option specified, no operation done" exit fi if [ ! -w "$FILE" ] then gksudo chmod a+w /sys/devices/platform/sony-laptop/kbd_backlight fi if [ "$MODE" = "on" ] then echo 1 > /sys/devices/platform/sony-laptop/kbd_backlight notify-send -t 8000 "Keyboard light turned on" else echo 0 > /sys/devices/platform/sony-laptop/kbd_backlight notify-send -t 8000 "Keyboard light turned off" fi
Then i map the key with this line in my bashrc
bind '"^[[19;5~": "/home/$(whoami)/bin/keyboard_backlight.sh off\n"' bind '"^[[20;5~": "/home/$(whoami)/bin/keyboard_backlight.sh on\n"'
