    Hi everyone,

    I’m looking into the ‘nomachine-terminal-server package’ for running 3d applications on a headless system with NVIDIA 3D hardware acceleration. Unfortunately I hit a road block, it seems if there is no Xorg running (because it’s a headless system)  NoMachine does not make use of the xorg.conf file, in particular the virtual desktop function. If I connect a screen, Xorg comes up and I’m able to share the physical screen, but that’s not what I want. Is there a way to get NVIDIA 3D acceleration running using a virtual desktop? I already tried the VirtualGL feature ( https://www.nomachine.com/es/AR05P00982 ), but unfortunately the application seems no the recognize the proper 3d context.

    Any help or advise would be appreciated.

    Best regards,

    Hello.

    VirtualGL needs a a running 3D X server in order to share the GPU with applications running in virtual desktops.

    I knew development is ongoing on VirtualGL to make it work on NVIDIA cards directly and remove the need for a running X server.

    Hello graywolf,

    Thx for sharing those information. I already figured that a running X server would be required to access 3D acceleration. Please correct me if I’m wrong, so if I do bring up an Xorg, it would be possible to create multiple virtual desktops which would utilize a single graphic card in parallel?

    Are you at liberty to shed any light on the timeline regarding that on going development?

    Best regards,

    Yes, multiple virtual sessions can share the GPU through a single Xorg server.

    About current state of VirtualGL, I’d suggest to keep an eye on VirtualGL users mailing list.
