Hi Jean-Marc!
I am having a bit of trouble picturing what you are doing. I can
imagine that you mean one computer accepting request for and allowing
X-terminals through the GDM application and then the application on
the screen allows you to choose again other computers (or perhaps GDM
applications running to provide access to other parts of the same
machine) which then allow you to attach thier X server via GDM?
My first thought is that you see the options disappear because they
are "full". The X-server requested has reached it's maximum number of
served terminals and so the server drops from the selection menu?
Something that closes all of the current sessions (gdm restart) would
cure the problem but you really need to understand what is happening
here if you want to fix it. To test my theory you could have one
person after another sign on to a specific server and see if it drops.
Have them sign on only (do nothing there!) since some applications do
appear to be attached to bugs if run.
You should put GDM and any supporting applications into "debug" (full
error reporting) and watch were they log the errors (usually in
/var/log - look at the applications documentation.
If GDM spawns a process with each user you could watch them with ps
run in a script ( ps aux | grep myprocess ).
Good Hunting!
Tod
