Setting Up for Linux Desktops

Create a desktop pool that contains the congured Linux virtual machines. See “Create a Manual Desktop
Pool for Linux,” on page 57.
Verify That the NVIDIA Display Driver Is Installed
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.
Prerequisites
n
Check that you installed the NVIDIA display driver.
n
Verify that Horizon Agent is installed on the Linux virtual machine. See “Install Horizon Agent on a
Linux Virtual Machine,” on page 41.
n
Verify that the Linux virtual machine is deployed in a desktop pool. See “Create a Manual Desktop Pool
for Linux,” on page 57.
Procedure
1 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.
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
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.
n
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.
n
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-t will not work.
Configure RHEL 7 for vSGA
You can set up an RHEL 7 guest operating system so that a Horizon 7 for Linux desktop can take advantage
of vSGA capabilities.
Install the VIB for the NVIDIA Graphics Card for vSGA on the ESXi Host
You must download and install the VIB for your NVIDIA GRID graphics card on the ESXi 6.0 U1 or later
host.
NVIDIA provides a VMware vSphere ESXi Driver for vSGA. For vSGA, an NVIDIA display driver is not
installed on the Linux virtual machine.
