[clug] Forcing x.org to ignore a specific keyboard

[Hal Ashburner]

This took too long to find out how it was done. So I'm sending it hear 
where it should be searchable and findable by the next schmuck who wants 
to do something like this.
I need the device nodes of the keyboard /dev/input/eventX
But I'm not using them as a keyboard so I want X to ignore it and just 
the program using it to actually use it.

Adding the following lines to:
/usr/share/X11/xorg.conf.d/10-evdev.conf
Would probably also work adding them to /etc/X11/xorg.conf which gets 
parsed before the above.


Section "InputClass"
         Identifier "1"
         MatchDevicePath "/dev/input/event2"
         Driver "evdev"
         Option "Ignore" "True"
EndSection

Section "InputClass"
         Identifier "2"
         MatchDevicePath "/dev/input/event3"
         Driver "evdev"
         Option "Ignore" "True"
EndSection

Note that consoles will still get keyboard events from the ignored 
device, just X will ignore it.

Work out which eventX nodes correspond to your specific keyboard by 
looking at the output of
cat /proc/bus/input/devices | grep "Name\|Handers"
(Enjoy the fun of xorg telling you your cameras, tv cards and pc 
speakers are keyboards)
