[Thinlinc-technical] sessions are immediately shut down on freshly installed thinlinc server

[Carsten Rose]

Which Linux distro do you use as thinlinc server, 'Ubuntu' (as the login 
process suggests)? Which version?

When you log in remote via tlclient, are you already running a GUI 
session on thinlinc server console at the same time? This might cause 
trouble.

Typically your provided xinit.log shows the problem - but not in your case.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

This shows your session ended 'regular'.

Maybe you like to try cinnamon or mate (apt install cinnamon). Check if 
you have the some problems there.
