Input Devices

[Waldo Bastian]

Attached some bright shiny pictures that reflect my current understanding.

The "X Configuration Client" asks "HAL" for available input devices, opens 
them, and passes the open file descriptor on to the "X server".

The "X Configuration Client" will be informed by "HAL" when a new device gets 
plugged in.

In the absence of "HAL" the "X Configuration Client" can fall back to a static 
configuration file. 

The "X Configuration Client" uses the DBUS² session bus to inform the "X 
server" about new devices (equivalent of XAddInputDevice)

Comments?

Can/should this be expanded to output devices as well? How would a modesetting 
library fit in?

Cheers,
Waldo
