Keyboard backlight on Xiaomi Notebook keeps turning off












0















Ubuntu 18.04 is installed on my Xiaomi Notebook 13".



I am having an issue with the keyboard backlight : after a few seconds without using the keyboard, the backlight of the keyboard turns off until you press any key.



How can I keep the light always on?



I can't find a setting in the BIOS nor in the setting menus.

          Most keyboard backlights are intended to work that way, turning off after a short time of not typing.



          With that said, there's probably some subdirectory in /sys/class/leds for your keyboard backlight. Mine is /sys/class/leds/dell::kbd_backlight. Inside that are several control files that you can cat to see what they're set to. You can echo to them with sudo to change them.



          With mine, sudo bash -c 'echo 46799s > stop_timeout' in that directory sets the backlight to stay on for half a day after pressing a key, which may not give you exactly what you want, but might be good enough.
          Perhaps yours is similar or there's some other file in your keyboard backlight subdirectory that you can write to to get the effect that you want.

          • I went through the whole /sys/class/ folder but couldn't find the keyboard nor anything linked to xiaomi. I guess some driver isn't working properly on linux. Thanks for your reply tho !
