I've been doing some investigation and have discovered the following. If I perform these commands the back-light changes:
echo 0 | sudo tee /sys/class/leds/asus::kbd_backlight/brightness echo 1 | sudo tee /sys/class/leds/asus::kbd_backlight/brightness echo 2 | sudo tee /sys/class/leds/asus::kbd_backlight/brightness echo 3 | sudo tee /sys/class/leds/asus::kbd_backlight/brightness Also there is a script called /etc/acpi/asus-keyboard-backlight.sh I thought maybe this script wasn't being called and remapped the keys to the script and it still would not work. So I manually entered each script line and tested which worked fine accept I couldn't test this line: if [ "$1" = down ]; then I assume the $1 variable is only passed when called by the keyboard handler or is it possible this is the problem? How do I discover if this is being passed? How do I figured out if the script is even being called by the keyboard handler? I have enough information now to make a workaround but would like to see this fixed in future versions. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1327828 Title: [Asus G53JW] Cannot change keyboard backlight brightness Status in “linux” package in Ubuntu: Confirmed Bug description: When pressing function key plus F3 or F4 the backlight on the keyboard does not change.
