Thread: Multiple user remote desktop persistent sessions

  1. #1

    Default Multiple user remote desktop persistent sessions

    Hello

    I am a researcher at the university of Brussels.
    At our department we do a lot of computational fluid dynamics eating huge amount of ram per machine.
    To have a more efficient use of our calculating facilities i want to enable 'multiple user remote desktop persistent sessions'.
    Preparing a calculation does take a smaller amount of ram.
    In the few days a calculation is running, other calculations can be prepared by other users.
    I have a few steps in mind, but after days of trying, I was not able to get this working on our new machines.

    1) What remote desktop protocol can we use?
    I tried VNC, but it is not very satisfying in quality.
    A tool as teamviewer is working better but it is not multiple user.
    X over SSH was working with decent quality, but not persistent.

    2) The remote desktop tool should be running at boot level, before anyone has logged in.
    How to start VNC at boot level in Gnome3?
    Where is the VNC configuration file to do this?

    3)The remote desktop tool should always start with a login screen while connecting.
    And of course it should be possible to disconnect without interupting the calculation.
    How do I configure a persisent session?
    How to configure GDM to do so?

    4)Maybe a little early to ask, but I want to use this also in clustered machines.

    Regards

    Manly

    Hi,

    You might look at a program called Xpra ( http://xpra.org/ ) which allows quite a few things ( http://xpra.org/trac/wiki/About ) - there's also Concurrent multi-client connections (experimental) in the works.

    There's isn't the latest version in the SUSE build service at the moment (0.13) but I doubt it's too much of a problem to provide an RPM for it.

    Many thanks for the response.
    I realy enjoyed the xpra and winswitch discovery.

    Any hints to realize those 'persistent sessions' with mini-PC thin clients?
