X-Windows How To

Hello QNX-friends.

I need to connect to XDMCP host
and have some questions about X-Windows

  1. Is there possibility to do it with the help of
    X-Photon or not? (And how, of cource)

  2. Please advise me how to set properly
    environment variables for QNXFree86 (QRtP port)

  3. And may be someone knows
    what is ps/2 mouse driver name in /dev/…
    or somewhere else, it is needed for X configuration and
    now it’s enigma for me.
    (The default name is /dev/mouse, but I couldn’t find it there at all)

Many thanks in advance,
Evgeni
