    Default Tightvnc with gui without monitor

    OpenSuse 12.3 LXDE.

    How can I start my computer without screen but with pci-e GPU support (nvidia).
    Remote tightvnc without screen gives no gui and no nvidia gpu support?
    I only see twm with remote.

    Default Re: nvidia gpu drivers with no screen

    change the subject.
    opensuse 12.3 LXDE

    How can I use nvidia drivers with an gtx card without using a screen.
    I am using this pc as a rendernode so no screen is needed.

    I think you need to use a render software that can use it via the CUDA
    interface. Plus you will have to get the CUDA interface tools built and
    working on your box as well.

    I am using Nvidia cuda linux drivers works perfect and also using software for gpu rendering with cuda support (its called Cycles)
    I have build a render farm with nvidia cuda core cards in each node and tightvnc for remote.
    Without a monitor I have no access to the gpu which I need for gpu-cuda rendering.

    I am really missing what you are asking for then. Is there an issue with
    getting nvidia working on your render farm management machine while using
    tightvnc?

    Yes that's the problem because there is no monitor connected to the render nodes the nvidia driver is not working anymore.
    I want the rendernodes run without a monitor as you can see on the picture.
    Only without a monitor I have no access to the gpu which I need for gpu-cuda rendering with ssh or tightvnc.

    OK. Here is the normal hookup:

    ---------------------------------------
    | |
    |--------- render farm -------------|
    | |
    ---------------------------------------
    |
    |
    --------------
    | |
    | control |
    |workstation |
    | |
    --------------
    | |____________________
    | |
    -------------- ----------------
    | Monitor | | Monitor |
    | | | |
    -------------- ----------------

    The only place you need normal nvidia drivers in the control workstation
    to drive its monitor. The real rendering power comes from the CUDA
    enabled machines in the render farm. Normal drivers there are unwelcome
    and unneeded (you wouldn't want to hookup a few dozen monitors and suck
    up all the processing power you built the render farm for, would you?).

    I am looking for a nvidia rendernode only driver.

    That is in the rendering software kit that uses the CUDA extensions. What
    did you say you use?
