You can verify that the NVIDIA display driver is installed on a RHEL 6.6. virtual machine by displaying the NVIDIA driver output in a View desktop session.

Prerequisites

Procedure

  1. Restart the Linux virtual machine.

    The View Agent startup script initializes the X server and display topology.

    You can no longer view the virtual machine display in the vSphere console.

  2. From Horizon Client, connect to the Linux desktop.
  3. 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

Results

The user can access the NVIDIA graphics capabilities on the remote desktop.

After installing the NVIDIA driver, if you upgrade the Linux kernel, View Agent might not be able to communicate with View Connection Server. To resolve the problem, reinstall the NVIDIA driver.
