Horizon Agent for Linux has some dependency packages unique to a Linux distribution. You must install these packages before installing Horizon Agent for Linux.


Verify that a new virtual machine (VM) is created in vCenter Server and your Linux distribution is installed on the machine.


  1. Install the mandatory packages that are not installed or upgraded by default. The installer breaks the installation if any package does not meet the requirement.
    Table 1. Mandatory Dependency Packages

    Linux Distribution


    RHEL or CentOS 7

    Upgrade VMware Graphic driver for 2D desktop and vSGA desktop.


    This option is not application for vDGA and vGPU as they use NVIDIA Graphic driver in the VM.

    yum install mesa-libxatracker xorg-x11-drv-vmware mesa-private-llvm mesa-dri-drivers

    After updating, packages should be below version or newer:

    • xorg-x11-drv-vmware-13.0.2-7.20150211git8f0cf7c.el7.x86_64

    The update is not available for CentOS default online repository. You must enable the CentOS continuous release (CR) repository.

    yum-config-manager --enable "CentOS-7 - cr"

    After upgrading VMware Graphic driver, you can disable the repository again.

    yum-config-manager --disable "CentOS-7 - cr"
