--- Comment #8 from [email protected] --- I experience this as well, exactly the same behaviour: After restart I can not see the keyboard brightness slider in the "Brightness and Color" widget. However I can set the brightness with dbus-send like described in a previous comment. However if I log out and back in again, the slider shows up (and works correctly as well). -- You are receiving this mail because: You are watching all bug changes.
