Hi,
I have an ubuntu 12.04 installed in a kvm host. In this ubuntu, I have installed x2goserver.
I have configured /etc/x2go/x2goagent.options with # X2GO_NXAGENT_DEFAULT_OPTIONS+=" -extension GLX"
Change the - to a + The - disables the specified X11 extension, the + enables it.
:-)
please, x2go-dev, at least to me, the text in the config file has not been clear. Could you add some note about this?
We didn't invent the convention of +extension vs -extension. Neither did NoMachine when they were writing NX. It is the convention of upstream X.org (and XFree86 before them.)
That said, I agree that we should add a note and/or clarify. (I was thinking that myself when I replied to your email.) I'll look into that and probably have it done soon.
thanks!!!!
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 Many apps try to use it, but require a newer version of the GLX protocol, and thus fail.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, the 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.
Also let me know the following:
- Are you using X2Go Server from baikal (LTS) (4.0.0.x), or from stable (main) (4.0.1.x)? I have this:
ii x2goagent 2:3.5.0.27-0~446~ubuntu12.04.1
X2Go agent
ii x2goserver 4.0.1.15-0~847~ubuntu12.04.1
X2Go server daemon scripts
ii x2goserver-extensions 4.0.1.15-0~847~ubuntu12.04.1
(The 2 PPAs are here: https://launchpad.net/~x2go ) 2. What desktop environment are you running this under? There was recently a discussion about this problem on IRC, and it might be desktop environment related.
the server has UNITY, the client where I connect from kde, Debian Wheezy
- 32-bit or 64-bit OS?
the server 32 bits the client 64.
