Here's what we have for x2go processes:

ubuntu    3219     1  0 Feb02 ?        00:00:50 /usr/lib/x2go/x2goagent
-dpi 96 -D -auth /home/ubuntu/.Xauthority -geometry 1005x552+113+232
-name X2GO-ubuntu-51-1296672519_stDGNOME_dp24 :51
ubuntu    3690     1  0 Feb02 ?        00:00:00 /bin/bash
/usr/bin/x2goruncommand 51 3219 ubuntu-51-1296672519_stDGNOME_dp24 30008
gnome-session nosnd D
root     15119     1  0 Feb02 ?        00:00:04 /usr/bin/perl
/usr/sbin/x2gocleansessions

So there is an existing session.  I got detached from it when the
browser crashed.

It seems as though the client should either automatically attach to the
session or present the user with the list of sessions to take some action.
