The hosts file syntax is <address> <name> [<name> ...]
You should have added sobolev to the 127.0.0.1 line - the last one is just plain bogus.
However when I used the hostnamectl command I was able to get the dialog box asking me to continue or terminate what had to be 15 sessions. After terminating them all I got the X2Go screen for about 3 seconds and then it quit with the following segfault:
Yep, because that changed the hostname to a short name.

Looks like mate-session segfaulted... while running glxinfo?
This is a workstation, so it's likely that you installed some binary graphics card driver? Is that the case?
