How to change keyboard backlight color

Hello Sir, kindly need your help, how do i change keyboard backlight color on my tensorbook computer, instead of constant blue color.
I thank you in advance for response…


Hi Maker, in older BIOS versions you can change it without installing additional software. Currently in Linux it is stuck at the constant blue color.

Does this mean you can install additional software to change the color? One time, I was able to change the color but it has not worked since then.

On Ubuntu, try changing the GRUB_CMDLINE_LINUX_DEFAULT line in /etc/default/grub to:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_os_name=Linux acpi_osi=! acpi_osi=Linux acpi_backlight=vendor modprobe.blacklist=nouveau"

This should enable the keyboard backlight key combinations (Fn /, Fn *, Fn -, Fn +).

Edit: Don’t forget to sudo update-grub and reboot after editing the file.

This worked for me! I’m on Ubuntu 18.04 LTS.

Now to see if we can get the full RGB customizations…

Though I did get the keyboard backlights to work by ACPI kernel parameters as Harenbrs suggested, I was no longer able to “resume from suspend” without a hard reboot.

I compiled and installed the “tuxedo-keyboard” kernel module:

git clone
cd tuxedo-keyboard
make && sudo make dkmsinstall
sudo modprobe tuxedo_keyboard

I was then able to control the keyboard LEDs via the Fn key combos,
and was also able to control it with plain text!

while true; do for c in 0x{FF0000,FFFFFF,0000FF}; do
	echo $c | sudo tee /sys/devices/platform/tuxedo_keyboard/color* >/dev/null; sleep 0.2;
done; done
