Same problem here with a Dell Inspiron 7537 and I never experienced this with earlier Ubuntu versions. The backlight automatically turns on in the following situations for me (regardless of the previous settings):
1. When I turn on or restart the notebook. 2. When I wake up the notebook. 3. When I don't use the keyboard and the touchpad for a few seconds. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1510344 Title: Keyboard Backlight Turns on at boot To manage notifications about this bug go to: https://bugs.launchpad.net/dell-sputnik/+bug/1510344/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
