[X2Go-User] x2go disconnect timeout

[Ulrich Sibiller]

Hello Hanno,

X11 does not have a reconnect feature for clients. When the X server
dies, they die, too. So I am not really sure what you are describing
by "reconnect". In case you close your laptop the network connection
will go down. The x2goagent will notice after some time that the other
side (the laptop) is not answering/sending data anymore and will
detect a DISPLAY failure (since the remote X server is not available
anymore) and suspend the session.

If you have configured sleep=0 then your applications (meaning
Xclients running on the server side, connecting to the x2goagent) will
not notice any change as the x2goagent is still there, otherwise they
will be slowed down until x2goagent is woken up again by an x2goclient
that wants to connect.

I am not aware of an auto connect mechanism once the network is back
but on the other hand I am not deeply involved with the internals of
x2goclient and/or x2goserver.
