I'm setting up 3 seat multiseat (I use it in my company) but getting 
things embedded down on 1 seat, then I will add the other two.
I took "Device" setting out, and tried to use "Phys" instead, as I 
wondered if /dev/input/event3 would remain event 3 if evdev was wavering 
for some reason.
Are you saying it is safe to use the event numbers? That is simpler.
I'll add in the AutoAddDevices - thanks for this.

Drat :-(
Now to plough through nvidia drivers until it works?
I gather the nouveau drivers wont work for multiseat, so I have to use 
proprietary nvidia?
In etc/gdm/gdm.conf-custom I had to fire up 3 servers - do I need to do 
this for KDM (where?)

Thank & regards,
Zoltan
