Also, I have solved this, but I still have problems with some software that under a remote virt-manager is working but not under x2go.
If I run a graphical python qt program I got:
python: Fatal IO error 11 (Resource temporarily unavailable) on X server :5
and if I run for instance gazebo, I got:
X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 147 (GLX) Minor opcode of failed request: 5 (X_GLXMakeCurrent) Serial number of failed request: 22 Current serial number in output stream: 22
Any idea?
We've disabled GLX by default because It causes many applications to not work. The reason is that our "X server", nxagent 3.5.0.x, is based on X.org 6.9, from 2005. Therefore, nxagent implements a very old version of the GLX protocol. Many apps try to use it, but require a newer version of the GLX protocol, and thus fail. You can read more about this problem here: http://wiki.x2go.org/doku.php/doc:de-compat (I just wrote that wiki page yesterday. Feedback is welcome.)
well, in my case there's no a problem of desktop, it's of application. So,

wiki is too much desktop centric. You asked feedback ....
Does gazebo require 3D acceleration?
yes ... if relays in OGRE libs.
If not, try running it with GLX disabled. If you are still having trouble running it, let me know and I'll test gazebo on a KVM/virt-manager Ubuntu 12.04 VM at my home.
I will send you in private a virt machine to test.
Good news and bad news.
:-)
Bad News:
It looks like nxagent (and therefore X2Go) is too old to run OGRE apps linked against Ubuntu 12.04's libraries. Maybe it could be recompiled against older x server libs and run, but I don't have time to try that .
I also was unable to run it under cygwin X11 for some reason.
Ok, so as you said, the problem is the nxagent is too old.
Good News:
I was able to run Gazebo and the OGRE's "SampleBrowser" under KVM & virt-manager using SPICE and QXL. I am not sure if my host system was providing the new (experimantal) virtio-gpu or not. The OGRE SampleBrowser ran surprisingly well.
so, may I understand that you connect remotely to the host and run virt- manager and then visualize the box?
I successfully did this on both your VM and a VM i created with the original 12.04 HWE stack.
On your VM, i first ran this command to make sure that the 13.10 HWE X server and X libraries are installed. You have a bunch of 12.04 HWE X libraries installed, but they are not supported with the 13.10 kernel that you have (kernel 3.11).
sudo apt-get install --install-recommends linux-generic-lts-saucy xserver-xorg-lts-saucy libgl1-mesa-glx-lts-saucy
Ok
To run the OGRE SampleBrowser, I ran this package installation command:
sudo apt-get install ogre-samples ogre-tools ogre-doc
Then just run: SampleBrowser
Screenshots (from my VM, but your's worked too): http://imgur.com/a/zwPz9
Done, worked with virt-manager but not connecting with x2goclient.
My system: Host: Fedora 20 64-bit with all the latest updates. Guest: Ubuntu 12.04 64-bit with original 12.04 HWE stack. Packages installed include: xubuntu-desktop spice-vdagent libtxc-dxtn-s2tc Client: virt-viewer 0.6.0 64-bit on Windows
Other notes: On my VM, I installed spice-vdagent. This caused MATE 1.6.0 (from the mate-desktop.org) repo to fail to launch, but it XFCE still worked. On your VM, it is not installed.
it runs Unity.
Also, remember that to enable remote SPICE displays, you have to set the settings on the "Display" in virt-manager. You may have to remove and add the display for those settings to be adjusted.
well, I'm I bit lost. I have configured in the host the spice and qxl. I runs better than using the default VGA, cyrrus.
Otherwise, I think that I cannot use X2Go here :-( I'm searching another solutions.
Just, for curiosity, X2Go will be ready to use with wayland?
Regards,
Leopold
