How to disable backlit keyboard in Ubuntu 20.04 (Dell Latitude)

  • 772

I would like to disable the keyboard backlight on a Dell Latitude E5570.

According to the official documentation this should be possible by selecting "disable" for the corresponding BIOS parameter. I did this several times but the BIOS setting automatically goes back on every time I boot to Ubuntu.

I found these old bug reports which appear to be related, but I don't know if these still apply for 20.04:

Any advice?

    Try pressing Fn + Space Bar. Fn is the key between the windows key and ctrl.

    This is the shortcut for toggling the backlight on the keyboard for my Lenovo laptop. It might be the same for Dell.

    Edit: For the Dell Latitude, the toggle command is Fn + F10.
