Headless nVidia Mini How-To

VirtualGL works fine with headless nVidia GPUs (Tesla), but there are a few additional steps that need to be performed in order to run a headless 3D X server on those GPUs. These steps should be performed after installing the nVidia proprietary driver but before installing VirtualGL:

1. Create an appropriate xorg.conf file for headless operation:

sudo nvidia-xconfig -a --use-display-device=None --virtual=1920x1200

2. Run lspci to obtain the bus ID of the GPU. Example:

00:03.0 VGA compatible controller: NVIDIA Corporation GK104GL [GRID K520] (rev a1)

3. Edit xorg.conf and add the bus ID you obtained above to the "Device" section. Example:

Section "Device"
    ...
    BusID          "PCI:0:3:0"
EndSection

4. Reboot the machine and proceed with the VirtualGL installation instructions.
