Bug#440495: xserver-xorg-input-synaptics: Keyboard doesn't work after turning touchpad off and on

[Ove Kaaven <ovek@arcticnet.no>]

Hmm, come to think of, I think this behaviour (when the touchpad is
turned on) is consistent with X receiving keyboard input that makes it
think the Help key is held down. An experiment with Fn-F1 shows that
while the key is held down, the keyboard is grabbed, just like what I
see when the touchpad is turned on, but the Gnome help is not actually
launched before the key is released.

(Perhaps on KDE it's different, it could be brought up immediately and
continuously re-focused as the help key is thought to be held, maybe
even using autorepeat.)

Hah, I think I'll try going into the Gnome hotkey preferences and just
turn off that Help hotkey, maybe that'll work around the problem...
