[Bug 1263080] [NEW] keyboard stops working KDE

[SA]

Public bug reported:

Since a few updates over the last two weeks the keyboard on my laptop
(macbook air 4.2) stops responding 2-3 times a day on light use.  I find
no messages looking at the system logs (via dmesg).  KDE seems unaware
of the problem.  The mouse works and the only way I can "fix" the
problem is to use the mouse to logout or reboot. I cannot use the
keyboard to switch to a console screen. The only button that does
anything is the power button.

Previous to the last two weeks it has been fine although I recall a
similar problem a year or so ago (I think this was less frequent and one
day just was fixed presumably after some update).

I use xmodmap to remap the apple keys to mouse buttons to overcome the
lack of a three button mouse and during the same period I've had a few
instances recently when this remapping has been "forgotten" and has
needed to be reapplied.

I have also noticed that when the keyboard is dead the caps lock key and
the keyboard backlight don't work (caps lock key is a good test since it
normally  lights up).
