Bug#1089680: powerdevil: Keyboard backlight brightness not controllable on first login

[Richard Hansen <rhansen@rhansen.org>]

Package: powerdevil
Version: 4:6.2.4-1
Severity: normal
Tags: upstream

After rebooting and logging in to KDE (Wayland), the keyboard backlight is not
controllable via KDE, neither by keyboard shortcuts nor by the Brightness and
Color widget (it doesn't even appear there).  Setting the brightness by writing
a value to /sys/class/leds/chromeos::kbd_backlight/brightness works.  If I log
out and back in, KDE works as expected.  This used to work before the recent
upgrade to Plasma 6.
