--- Comment #5 from Jan Kundrát <jkt at kde.org> ---
Just FYI and as a random data point, my T460s with intel_backlight which once
again has a type = raw contains "enabled" in its device/enabled property.
Despite that, I was too hitting this bug.

However, it's possible that I might have always logged in with this laptop
docked while I was debugging this. If that's the case, SDDM shows output on the
laptop's internal screen as well as on some external one. kscreen switches the
internal output off because that's what I want to have.

It's possible that there was a race between kscreen switching and powerdevil
deciding to ignore stuff. Thanks bshah for fixing this.
