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