[X2go-dev] x2go not working on ubuntu 10.10?

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.
