Hi all,
I'm trying to use x2go-server on a headless machine for virt-manager with x2go-client on Win10. I did not install any desktop environment.
x2go terminates the connection immediately, no window is shown. If I use VcXsrv with putty, virt-manager is working fine.
Here are some logs from the server:

Do I need to install a window manager on Ubuntu to run just a single apllication with x2go?
Thanks!

No. Please post the output of
cat /etc/x2go/x2goagent.options
and
dpkg -l | egrep 'x2go|nx'
I remember having issues with virt-manager via X2Go in the past, but I thought these were fixed ...

Now I remember how I solved this for me: I actually switched from Single Application mode to Published Application mode.
First, select "Options" from X2GoClient's top menu bar, then "Settings". On the "General" tab, check "Display Icon in system tray", and after checking that box, check all four boxes below it. Click OK.
Then, click the "Hamburger Icon" in the X2GoClient session tile's lower right, select "Session Preferences", then on the "Session" tab, set the "Session Type" to "Published Applications". Click OK.
to run virt-manager, start the session by clicking on the tile. When the X2Go icon appears in the taskbar's Notification Area (AKA "Systray"), right-click it, then select <Your Session name>/System/Virtual Machine Manager.
Ta da, virt-manager is running.

CCing Mike#1, as he has some python knowledge and virt-manager is a python program (called by a bash wrapper, no idea why) ...
What seems to happen is that X2Go doesn't detect virt-manager as an X application.
If I write a wrapper script like so:
#!/bin/bash timeout 10 xterm & # background xterm, don't call virt-manager from it /usr/bin/virt-manager
Then virt-manager will start - but will die after 10 seconds, when "timeout" kills the backgrounded, empty, idle xterm session. I would understand this behavior if virt-manager was called from *within* xterm, but as you can see, it is called separately.
@Mike: Any idea as to what's going wrong here and how to fix it?
Kind Regards, Stefan Baur

You need a desktop environment. If you are using the default gnome,then you also need gnome-flashback-session. Else install mate which works perfectly with x2go.

No, you don't.
The fact that you can start a script, have the script start xterm in the background, and then virt-manager clearly proves your statement wrong.

Ok if you're expecting a display as if you had a head on a local machineyou need a desktop environment. Granted you can do other things without but then you can do that with ssh -X so why bother?

I've installed x2goserver & x2goserver-xsession on ubuntu servers in the past and then access that server via an x2go client and it worked fine without installing a full Desktop Environment although its a bit sparse :-)

Yep might be a good thing to do. It would be better if it still hadthe efficiency it had in the early days. Early implementations of x2go, I could fire up firefox on the server and watch a video and for the most part it was smooth. These days I only get about 10 frames per second, something has slowed.

Uh, yes, we've been discussing this on the list quite a while ago. It's not an X2Go issue, but a Firefox issue - they changed their rendering engine to something that is super fast on a local machine, but is slow as molasses on remote connections. The only option used to be Pale Moon
- a Firefox fork - that kept the old engine, but only up to version 27. 28 is broken as well, and we could currently use some more funding and/or additional manpower for the ongoing research/development project to get PM 28 up to speed again.
See the thread "Firefox Browser Performance via X2Go - and a call for help on behalf of X2Go and Pale Moon" dated "28.10.17, 13:26" in the list archives: <http://lists.x2go.org/pipermail/x2go-user/2017-October/004601.html> (Initial crosspost to X2Go-User and X2Go-Dev) <http://lists.x2go.org/pipermail/x2go-dev/2017-October/012168.html> (Thread on X2Go-Dev, with a sole reply by Ulrich Sibiller).
Since there were no other replies back then, we were on our own, so work is proceeding veeeery sloooowly.

Ok, thanks for the list. There is not an aweful lot to like about thecurrent firefox.

Okay, so this video is roughly 6 years old (which is why it's marked "unlisted") and with a German UI, but it shows pretty well how Published Application mode works:
<https://youtu.be/PMQH7sJC47Y?t=73>
Watch the context menu popping up from the X2GoClient icon in the Taskbar's notification area (AKA "Systray").
