The Linux device on which you install Horizon Client, and the peripherals it uses, must meet certain system configurations that have been tested and are officially supported by VMware.


These system requirements pertain to the Horizon Client for Linux that VMware makes available. In addition, several VMware partners offer thin and zero client devices for Horizon 7 deployments. The features that are available for each thin or zero client device, and the operating systems supported, are determined by the vendor and model, and the configuration that an enterprise chooses to use. For information about the vendors and models for these client devices, see the VMware Compatibility Guide, available on the VMware Web site.

  • Starting with version 7.0, View Agent is renamed Horizon Agent.

  • VMware Blast, the display protocol that is available starting with Horizon Client 4.0 and Horizon Agent 7.0, is also known as VMware Blast Extreme.


i386, x86_64, ARM


At least 2GB of RAM

Operating system

The Horizon Client for Linux have been tested on the following operating systems for this release.

Operating System


Ubuntu 32-bit


Ubuntu 64-bit

16.04, 18.04

Red Hat Enterprise Linux (RHEL) 32-bit


Red Hat Enterprise Linux (RHEL) 64-bit

6.10, 7.5

OpenSSL requirement

Horizon Client requires a specific version of OpenSSL. The correct version is automatically downloaded and installed.

Horizon Connection Server, Security Server, and View Agent or Horizon Agent

Latest maintenance release of Horizon 6.2.x and later releases

If client systems connect from outside the corporate firewall, VMware recommends that you use a security server. With a security server, client systems will not require a VPN connection.

Remote (hosted) applications are available only on Horizon 6.0 (or later) servers.

Display protocol

  • VMware Blast (requires Horizon Agent 7.0 or later)

  • PCoIP

  • RDP

Screen resolution on the client system

Minimum: 1024 X 768 pixels

Hardware requirements for VMware Blast and PCoIP

  • x86- or x64-based processor with SSE2 extensions, with a 800MHz or higher processor speed.

  • Available RAM above system requirements to support various monitor setups. Use the following formula as a general guide:

    20MB + (24 * (# monitors) * (monitor width) * (monitor height))

    As a rough guide, you can use the following calculations:

    1 monitor: 1600 x 1200: 64MB
    2 monitors: 1600 x 1200: 128MB
    3 monitors: 1600 x 1200: 256MB

Hardware requirements for RDP

  • x86- or x64-based processor with SSE2 extensions, with a 800MHz or higher processor speed.

  • 128MB RAM.

Software requirements for Microsoft RDP

Use the latest rdesktop version available.

Software requirements for FreeRDP

If you plan to use an RDP connection to Horizon desktops and you would prefer to use a FreeRDP client for the connection, you must install the correct version of FreeRDP and any applicable patches. See Install and Configure FreeRDP.

Other software requirements

Horizon Client also has certain other software requirements, depending on the Linux distribution you use. Be sure to allow the Horizon Client installation wizard to scan your system for library compatibilities and dependencies. The following list of requirements pertains only to Ubuntu distributions.



    Beginning with Horizon Client 4.2, libudev0 is required to launch Horizon Client. By default, libudev0 is not installed in Ubuntu 14.04.

  • To support idle session timeouts:

  • To support Flash URL redirection: (The file is no longer required.)

  • To improve performance when using multiple monitors, enable Xinerama.
