The fix (which is also a workaround you can apply yourself) is: https://gitlab.freedesktop.org/upower/upower/merge_requests/12/diffs?commit_id=0a9d9ab4949effb20e77aa52e7b4ee07e776fc0d ** Summary changed: - Separate keyboard brightness control keys (down/up) don't work + Keyboard brightness control keys (down/up) don't work ** Description changed: - https://gitlab.gnome.org/GNOME/gnome-settings-daemon/issues/100 + https://gitlab.freedesktop.org/upower/upower/issues/73 --- On laptops with two separate (down,up) keys to control the backlit keyboard, both keys seem to do nothing. The OSD for the backlit keyboard is displayed but no progress bar and no actual effect to the backlight. Almost as if the shell only understands laptops with a single key for controlling the keyboard backlight... Bug verified in cosmic on: * Asus UX331UAL * Apple Macbook Pro 12,1 * Apple Macbook Air All of them have these keys and they all fail in the same way. However it is not a kernel bug. The kernel interface (/sys/class/leds/*::kbd_backlight/*) works when I write to it directly. This seems to be a problem with Gnome Shell only.
