Title:
Keyboard backlight not working on Asus ZenBook Flip UX561UD laptop in
Cosmic 18.10, works with 18.04.1 desktop installer live image
Status in linux package in Ubuntu:
Confirmed
Bug description:
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 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
The keyboard backlight works perfectly when booting from the 18.04.1
desktop live image, Most other Fn+Fx special keys on this laptop work
(display brightness, touchpad off, sound etc.) 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
