Tesla P4 remote rendering, VNC and Centos 7

Graphics / Linux Linux

Hi all,

I am using a Tesla P4 card in a Centos 7 operating system. I have installed “nvidia-diag-driver-local-repo-rhel7-390.46-1.0-1.x86_64.rpm” following installation instructions in the download page. I had blacklisted nouveau drivers and verified them by checking lsmod| grep nouveau. The system is a Dell Poweredge 730 and has a “VGA compatible controller: Matrox Electronics Systems Ltd. G200eR2”.

The issue is that when I VNC into the machine and launch nvidia X server settings a popup appears saying “You do not appear to be using the nvidia X server” and then the screen goes blank.

Could someone please help me with this issue?

I am attaching the Xorg.0.log and nvidia bug report.

Thanks
Arjun

Logs look ok. Are you sure you’re actually connecting to the nvidia xserver e.g. through x11vnc or are you using xvncserver? That’s a plain software xserver.

Thanks generix. I understood the difference only after I posted this. Yes, I am able to connect via x0vncserver to the display 0.
Is there a way if I wanted hardware acceleration on other vncservers also, without using virtualGL.

You would either have to start a separate xserver on the nvidia gpu for each vnc client you want to use or set up virtualgl.

I use tigervnc server, I am not sure how to start a separate x server for each client. Could you please point me to some reference or help me with this.
