You can verify that the NVIDIA display driver is installed on a RHEL 6 virtual machine by displaying the NVIDIA driver output in a View desktop session.
- Restart the Linux virtual machine.
The Horizon Agent startup script initializes the X server and display topology.
You can no longer view the virtual machine display in the vSphere console.
- From Horizon Client, connect to the Linux desktop.
- In the Linux desktop session, verify that the NVIDIA display driver is installed.
Open a terminal window and run the glxinfo | grep NVIDIA command.
The NVIDIA driver output is displayed. For example:
[root]# glxinfo | grep NVIDIA server glx vendor string: NVIDIA Corporation client glx vendor string: NVIDIA Corporation OpenGL vendor string: NVIDIA Corporation OpenGL version string: 4.5.0 NVIDIA 346.47 OpenGL shading language version string: 4.50 NVIDIA
The user can access the NVIDIA graphics capabilities on the remote desktop.
After verifying the installation of NVIDIA display driver, perform the following tasks for installation to work correctly.
If you upgrade the Linux kernel, Horizon Agent might not be able to communicate with View Connection Server. To resolve the problem, reinstall the NVIDIA driver.
Set the NVIDIA GRID licensing in the Linux VM. See NVIDIA documentation for more information. Linux desktop will not work correctly if licensing is not set. For example, auto-fit will not work.
