I'm running the following: Ryzen 7 1700, Prime X370 Pro, 64GB RAM, Vega Frontier, Proxmox (most recent beta). I've passed the gpu through to an Ubuntu 16.04 guest OS.

I have a remote computer on AWS with Nvidia GRID card K520 and want to remotely render 3D graphics. I use Ubuntu 14.04 - 64 bit. Remote and local.For remote connection and OpenGL rendering we use VirtualGL and TurboVNC (*amd64.deb).

Ubuntu is running and I can SSH into it, but it seems to have no graphics adapter available for display! Edit: I think this was the case because I needed to restart the entire Proxmox node for various reasons before the card could be picked up again after updating the.conf; See 'Final note' in reply below. Lspci grep -i vga 00:02.0 VGA compatible controller: Cirrus Logic GD 5446 00:05.0 VGA compatible controller: NVIDIA Corporation Device 1b06 (rev a1) 00:06.0 VGA compatible controller: NVIDIA Corporation Device 1b06 (rev a1) dmesg grep NVRM.

I properly installed VirtualGL and TurboVNC and I have Nvidia drivers.

As I understand VirtualGL uses display :0 and TurboVNC uses display :1 on remote machine.

When I connect to the remote machine and I want to run a 3D app (via vglrun ) it gives me error:

extension 'GLX' missing on display ':0.0'.

I don't undrestand how VirtualGL works on a remote machine with TurboVNC, how it uses the display :0 and if it's ok.

Do I need something to setup (.conf, graphic driver). I tried installing it over and over, tried serching for answer, but I didn't find a solution.

I. Recap

The remote computer on AWS (EC2 gl2.2xlarge) is running on 64-bit Ubuntu 14.04. I properly installed VirtualGL, TurboVNC and Nvidia 352.63 drivers (cuda 7.0).

I remotely connected to the aws instance.
Run the TurboVNC server: /opt/TurboVNC/bin/vncserver
Run TurboVNC client and connect to remote computer: /opt/TurboVNC/bin/vncviewer
When I wanted to run application on the remote pc there was the error./opt/VirtualGL/bin/vglrun <application>

Error: extension “GLX” missing on display “:0.0”

II. Solution

First type on remote pc:sudo xinit &
Run application on remote pc/opt/VirtualGL/bin/vglrun <application>

Example:/opt/VirtualGL/bin/vglrun glxgears

sudo xinit &

What does sudo xinit & ?

To get OpenGL applications to run on the remote computer I need to start a second X Server which VirtualGL uses to talk to the NVIDIA gpu. The second X Server will start with the sudo xinit &.
