Problems With X2go

CentOS 5 Comments

I have installed x2goserver on a CentOS8 server.

Yesterday, after the installation I was able to connect by means of x2go. Today I get the following error ( /var/log/messages)

/usr/bin/x2gostartagent[2677]: no free display number available, cannot start new session.

Has anyone had the same problem?

Thanks.

Bye

  • This is not the answer to your question, but if this is a new install and not an existing installation, consider NoMachine
    <https://www.nomachine.com/>. It’s free and so much better than x2go it’s hard to even compare the two.

  • Thank you, Jonathan, that may help me. I had to say no to one of my users who asked to install nomachine for him. We are university, i.e., not individual (aka home) users. But xpra sounds better than what I told my user to use (vncserver, VNCviewer over ssh).

  • I have a somewhat dated page on x2go and xpra. It was made when nomachine updated their client (I was just using it for home use) and I didn’t like the changes they had made.

    I haven’t kept it up to date, especially the xpra part, but it does give a quick start.

    (It was written around CentOS 6.x time). I still use x2goclient on a FreeBSD workstation to get to a CentOS-8.x server.

  • I used nomachine, but besides not being free it had a limit on the maximum number of sessions that could be opened at the same time. The server must be used (for non-commercial purposes) by several users.
