Hello everyone,
Here's my summary. First, let's look a resume of my original question:

I don't know the exact answer to my problem but it seems to related to the
deletion of some files in the /tmp directory. All I know is to make It
wouldn't happen again (specially during a training), I removed the
authentication on the XServer by modifying the startup line. Since this
Network segment is not connected to anything, it's pretty safe for me to do
so.
Here are the options that Openwin take concerning security and/or
authentication:
/usr/openwin/bin/openwin -auth magic-cookie
/usr/openwin/bin/openwin -auth sun-des
/usr/openwin/bin/openwin -noauth
The modify the authication procedure for the Openwin X server. Really
interesting info on that and the .Xauthority files in the Answerbook.
Thanks a lot:
