Send X2go-dev mailing list submissions to x2go-dev@lists.berlios.de 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 /usr/bin/x2goagent: line 1: -e: command not found

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

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 Ubuntu 10.10 image, did you get the image from Canonical?

please check, if your /usr/bin/x2goagent look so:
#!/bin/bash X2GO_LIBS=/usr/lib/x2go LD_LIBRARY_PATH=/usr/lib/x2go exec /usr/lib/x2go/x2goagent $@

email: oleksandr.shneyder@obviously-nice.de web: www.obviously-nice.de
--> X2go - everywhere@home
The file /usr/bin/x2goagent looked like this:
-e #!/bin/bash X2GO_LIBS=/usr/lib/x2go LD_LIBRARY_PATH=/usr/lib/x2go exec /usr/lib/x2go/x2goagent $@
I removed the "-e " in front of the first line, but it did not have any effect, the same error still persists.

I can also confirm that this bug is present in ubuntu 10.04 LTS,
I followed the steps in this article:
http://cloud.ubuntu.com/2010/11/show-off-ubuntu-desktop-on-cloud/
(Except I skipped the optional step. Also the first time I skipped the
apt-get distupgrade to see if it was caused by Ubuntu 10.10. The
second time I tried it with the distupgrade as well, to no avail.)
I used the official Canonical 32 bit Ubuntu AMI (ami-a2f405cb found on http://uec-images.ubuntu.com/releases/10.04/release/). I am using a m1.small instance.
Here is the same log again, but this time from my new attempt:
