[X2Go-User] problem getting x2go to work.

[Jon Gilbert]

I have a server set up which is Ubuntu 12.04.4 LTS (GNU/Linux 3.2.0-64-virtual x86_64). 

I installed ubuntu-desktop as instructed by the x2go wiki. I also did these steps:

sudo apt-get install x2goserver
sudo apt-get install x2goserver-xsession
sudo apt-get install sqlite3
sudo x2godbadmin --createdb

I try to connect from the Mac client (tried all the versions) and it always fails. It just hangs at the screen where it's trying to connect. I set the server log level to debug and it just says:

It repeats this over and over as the processor runs at 100% on the server, being hosed by the several x2go processes that seem to be stuck in an infinite loop.

You'll notice that it runs gnome-flashback.sh in my command, that's because it doesn't work to connect the normal way either, so I tried the steps outlined in this e-mail from this list:
http://lists.x2go.org/pipermail/x2go-user/2014-May/002260.html

(I find it annoying that it doesn't work with Gnome 3 according to that e-mail, yet it doesn't mention this incompatibility in a conspicuous way anywhere on the x2go site.)

Anyway I followed all the steps 1. through 6. in the above-linked e-mail, to no avail, because it did nothing at all towards making this work. 

BTW my server is on EC2. Don't know if that matters. And yes, I have 

Please let me know what is going wrong here and what I can do to fix this. Thanks. BTW I do have the latest version of XQuartz installed as my client, and I did set it up to accept remote connections and all that. The connection gets made no problem; the problem definitely seems to be on the server.
