Yes ;-)
Sorry, I meant I disabled the firewall on the client, maybe it was
blocking the connections to the tunneled port on localhost (I think it
is localhost:30000 or something). But it appears it wasn't.

It also works from ubuntu 9.04. However, I still would like to run it
from my 9.10 box as this is my workstation :)
I thought it might be a firewall issue, so I tried `sudo ufw disable`
but still the problem persists.

Things I tried, but did not work:
- check if user is a member of "x2gousers" group in /etc/group
- check if user is a member of "fuse" group in /etc/group
- reset password of user to make sure not entering wrong password
- set DisallowTCP to false in /etc/gdm/gdm.schemas
- remove "-nolisten tcp" from /etc/X11/xinit/xserverrc
- run the command `xhost +x` (from the command line it gives an
error "xhost: unable to open display """ caused by no active
display (and therefore no $DISPLAY environment variable), so I
also tried entering this from within an VNC session and the
command completed normally, also tried this with an Xvfb xsession)
- allowed login with passwords in /etc/ssh/sshd_config
- restart ssh service
- restart EC2 instance
- tried installing packages x2goserver-home, x2goserver-one,
x2goserver (and removed installations between trying different
packages)
When I tried different NX servers, I always used the corresponding
client (I have been careful not to mix up different clients with
different servers). For x2goserver I am using x2goclient from the
repository, I am using it on Ubuntu 9.04 desktop 64-bit edition.
My settings are:
name: test
hostname: <EC2 public dns here>
login: ubuntu
ssh port: 22
use rsa/dsa key for SSH connection: <tried different settings,
tried to leave it empty, tried the key I got from amazon, tried a
key which was sitting in ~/.ssh/id_rsa; tried all possibilities
with and without password>
session type: GNOME
In all cases the error on the server stays the same.

I've been using AMI's from Alestic or one's I build myself.
But x2go's been working solid.
So you did all the normal things like change /etc/ssh/sshd_config
to allow login with passwords
and the user is a member of x2gousers 'group'
etc

Yes, it is an Ubuntu Server AMI with ubuntu-desktop
installed, the desktop is working with VNC so that part seems
to have gone OK.
FYI it was an alestic.com <http://alestic.com> Ubuntu 10.10
image, did you get the image from Canonical?

Note sure what you are doing but I've got quite a few ubuntu
10.10 servers on amazon
that I connect to using x2go. Lack of the video card on
those AWS EC2 machines
makes no difference in regards to x2go.
But you have installed a "desktop" on those AWS instances?
If you created an instance from an Ubuntu Server AMI then
you would need to
/sudo apt-get install ubuntu-desktop/
or install some "light" desktop.

Hi,
I tried to get this working all night, but it seems there is
no way to
connect to an ubuntu 10.10 installation using x2go (package
x2goserver-home). When trying to connect, x2goagent is
complaining about
not being able to open a display (in the session log). The
machine is an
Amazon EC2 instance, which has no video card. I suspect this
is causing
the trouble. I have read it was working on ubuntu 10.04 by
the way, as
in
http://blog.restbackup.com/how-to-use-amazon-ec2-as-your-desktop
I also tried freenx, neatx and nxserver (from nomachine),
and they all
give similar errors. Tightvncserver on the other hand does
work, maybe
that's not so useful information, but just in case.
The server log says:
$ cat session.log

I'd really like to try NX, since it appearantly works faster
than VNC.
Please advice.
Kind regards,
