In case of a Linux host it's necessary to reboot the machine or restart the display manager to make this operative.Ģ) Setup Xorg for working in headless modeĢ.1) For NVIDIA GPUs and proprietary driver only, another possibility is to configure X.org to run headless (use -allow-empty-initial-configuration)Ģ.2) Install a Xorg dummy driver by creating fake EDID (Extended Display Identification Data) and use it in nf (EDID are stored in the monitor and read out by the GPU when monitor is connected) In this case NoMachine doesn't use its own virtual display because it detects that the X server running.Ī common solution, valid for all the supported Operating Systems, is to adopt a fake display dongle (also called 'dummy dongle') inserted in the video card port to simulate the presence of a screen and force the system to take full advantage of the GPU as if a real monitor is connected. This ability, enabled by default in the free edition of NoMachine, can be activated also in the commercial versions (see instructions for the Enterprise Desktop at the end of this article).Ī specific case which leads to black screen on Linux is when the X server is running but it is not rendering because the video card is turned off. NoMachine is able to detect when the X server is not running and run its own virtual display, which is an embedded X server.
