Comment # 2 on bug 887041 from Karl Cheng

It only shows on some computers. On other computers the keyboard backlight
can't be controlled from the UI (not sure if this is because of KDE or computer
itself).

This bug report hasn't had a response for years so it will have to be closed.

If someone can still reproduce this bug, please file a new bug with logs and
all necessary hardware information. Thank you!
