I've made a workaround. Since hardware buttons doesn't work, GNOME didn't ship UI controls to set an essential feature that is screen brightness, and brightness can be manually set by using xbacklight:
1. I created a PolKit policy allowing non-admin groups to use xbacklight tool. 2. I created two custom keybindings in GNOME settings to set brightness level with a key combination. In my case: * Shift+F1 runs "xbacklight -dec 10" which decreases brightness each time is pressed by 10 (hardware button is Fn+F1); * Shift+F2 runs "xbacklight -inc 10" which increases brightness each time is pressed by 10 (hardware button is Fn+F2). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1767001 Title: Brightness control not working in GNOME - Ubuntu 18.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1767001/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
