when i run ‘sudo systemctl --failed’ : [error]

[image] THIRU: Inspiron 15-3567 Right, so, by default that model has no keyboard backlight unless you custom update it. Only thing left is for you to [image] anon89812132: mask the service: sudo systemctl mask systemd-backlight@leds\:dell\:\:kbd_backlight.service

A error on running systemctl --failed

That is why i mentioned to mask the service … i don’t think you will get the keyboard light working anyway … What dell laptop model you have, maybe share?
