Two virtual machines (with a reasonable fresh install) don't<br>
give the problem. I haven't completed the whole test because I<br>
needed to install LXDE, or MATE.<br>
Most important conclusion is that the connection worked well.<br>
No segfault.<br>

I tried various desktops, all gave the "core dumped" message.<br>
<br>
Can we draw the conclusion that it is the SSH connection?<br>
How can I investigate this further? One thing I already tried was<br>
to run the remote sshd in debug. I noticed that it uses different<br>
connection methods between normal ssh and x2go.<br>
