Our application requires opengl 4.6 and our server RHEL 8.3 having NVidia RTX6000 , but we unable render display with NVIDIA .
NVIDIA-SMI 510.39.01 Driver Version: 510.39.01 CUDA Version: 11.6
If you want to access the nvidia gpu over vnc, you’ll have to connect it to a real Xserver running on the nvidia gpu, e.g. using x11vnc. Running vncserver just creates a virtual xserver running on software rendering.
Dear Team,
we installled tight vnc in rhel 8.3 , please share any guide for connecting to X server in nvidia gpu

A rough outline would be
- make sure the desktop is running on the nvidia gpu and not the on-board server graphics
- switch login manager from GDM to sddm/lxdm/xdm
- install tigervnc-server
- configure and run x0vncserver
Dear Team,
Please clear on this query.
We Installed the Nvidia Quadro RTX6000 in the master Node HPC cluster and let me know whether the card is compatible for rendering In Physical Host or it rendering works only for Virtualization.
attached is the card which we installed.

While it’s mainly built to be used in vGPU setups, it can also be used for host graphics, it will then create a virtual monitor.
Dear Team
Please let us know any additional Software required for creating virtual Monitor or installing the driver will be enough.
We are Using RHEL8.3

Installing the driver and creating an xorg.conf (so the Xserver doesn’t use the on-board graphics) should be sufficient.
Please find the xorg, but still facing issue with OPENGL application.

And the configuration.

This xorg.conf.d configuration snippet configures the X server to
automatically load the nvidia X driver when it detects a device driven by the
nvidia-drm.ko kernel module. Please note that this only works on Linux kernels
version 3.9 or higher with CONFIG_DRM enabled, and only if the nvidia-drm.ko
kernel module is loaded before the X server is started.

Did you install, configure and run vnc0server?
