When I hit Fn-F11 on my HP EliteBook 8440p, KDE disables the touchpad and all touchpad buttons. The key does not act as a toggle, so pressing it again doesn't enable the touchpad. Eventually the Internet told me to edit ~/.kde/share/config/ktouchpadenablerrc, which is not really a satisfying User Interface experience. Could Input Devices > Touchpad be given an Enable/Disable Touchpad checkbox? Reproducible: Always
What is the symbol written in your Fn-F11 key? Toggle or disable?
Looks like a key mapping bug. Not sure where the wrong mapping is defined. http://raftaman.net/?p=1535
The symbol on my Fn-F11 key is neither "toggle touchpad" nor "disable touchpad", it is "toggle ambient light sensor" -- see Chrisoph Feck's iink. There is a separate button/status light for "toggle touchpad", which does nothing -- it doesn't even generate X events. So, there are some defects somewhere, but they are separate from this wishlist item.
The only thing ktouchpadenabler is listen to keys and react to them, if your key is mapped wrong, there's nothing I can do. About your wish item, it has nothing to do with ktouchpadenalber, i've no clue where it belongs, but not to ktouchpadenalber that the only thing it does is again as i said react to the touchpad enable/toggle keys. Please Christoph (i think it is you that assigned to ktouchpadnenabler) can you find some other place to assign this bug to?
KDE offers no KCM module for touchpad related settings. Please report this issue to the bug tracker of your distribution.
