/* Devices and consoles are similar entities.  The idea is that
   a console represents a physical keyboard/mouse/other-input-source
   while a device represents a display where frames appear on.
   In the X world, a console is a "Display" while a device is a
   "Screen".  Implementationally, it can sometimes get confusing:
   under X, multiple devices on a single console are different
   "Display" connections to what is in reality the same Display on
   the same server.  Because of this, input comes from the device
   and not from the console.  This is OK because events are basically
   always tagged to a particular X window (i.e. frame),
   which exists on only one screen; therefore the event won't be
   reported multiple times even if there are multiple devices on
   the same physical display.  This is an implementation detail
   specific to X consoles (e.g. under NeXTstep or Windows, this
   could be different, and input would come directly from the console).
