You have been subscribed to a public bug: Repro: 1. Press Fn+F3/F4 in fresh install from current Cosmic desktop image, fully updated
-> Keyboard backlight should come on or change but doesn't. The gnome- shell pop-up icon for the keyboard backlight appears for both keys, but the icon's "progress" bar is not visible. Kernel version is linux-image-4.17.0-9-generic This is the same in X and Wayland session. In case it matters, Nvidia binary drivers are installed but Nvidia is switched off via Prime setting in nvidia-settings. Running with Intel drivers The keyboard backlight works perfectly when booting from the 18.04.1 desktop live image. When turning on light with 18.04.1, it is off again after rebooting into 18.10. (However 18.04.1 seems to freeze when shutting down from menu, I have to hard-shut it off). Most other important Fn+Fx special keys on this laptop work (display brightness, touchpad off, sound) except for the airplane mode key. However the airplane mode key only fails in gnome-shell but works on the console (this is filed as https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1791367) (Not working are a key that seems to mean "display off" and another of unclear purpose that never worked on any laptop I ever saw, maybe "presentation mode" as it seems to depict a flip chart or projection screen).
