System Requirements for Linux Client Systems

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

Note: These system requirements pertain to the Horizon Client for Linux that Omnissa makes available. In addition, several Omnissa partners offer thin and zero client devices for Omnissa Horizon deployments. The vendor and model of the thin or zero client device, and the configuration that an enterprise chooses to use, determine the features available for each client device and the operating systems supported. For information about the vendors and models for these client devices, see the Omnissa Compatibility Guides, available on the Omnissa website.

• Architecture

  x64, ARM (for thin client devices only)

• Memory

  At least 2 GB of RAM

• Operating system

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

  Operating System	Version
  Ubuntu 64-bit	20.04 and 22.04
  Red Hat Enterprise Linux (RHEL) 64-bit	8.7, 9.1

  Note: On RHEL 9.x/8.x and Ubuntu systems, Horizon Client only supports the X11 display server protocol. The Wayland display server protocol is not supported.

• OpenSSL requirement

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

• Omnissa Horizon deployments

  Horizon Client for Linux requires the latest maintenance release of one of the following deployment types:

  • Omnissa Horizon 8 version 2006 or later
  • Omnissa Horizon Cloud Service - next-gen
  • Horizon Cloud in Microsoft Azure

• Omnissa Horizon Connection Server

  Horizon Client requires the latest maintenance release of one of the following:

  • Horizon 8 version 2006 or later

  If client systems connect from outside the corporate firewall, it is good practice for you to use an Omnissa Unified Access Gateway appliance or security server. With a Unified Access Gateway appliance or security server, client systems do not require a VPN connection.

• Horizon Agent

  Latest maintenance release of one of the following:

  • Horizon Agent 2006 or later

• Display protocol

  • Omnissa Horizon Blast
  • PCoIP
  • RDP

• Screen resolution on the client system

  Minimum: 1024 X 768 pixels

• Hardware requirements for Horizon Blast and PCoIP

  • x64-based processor with SSE2 extensions, with an 800 MHz or faster processor speed

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

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

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

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

• Hardware requirements for RDP

  • x64-based processor with SSE2 extensions, with an 800 MHz or faster processor speed
  • 128 MB 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 remote desktops and you prefer to use a FreeRDP client for the connection, you must install the correct version of FreeRDP and any applicable patches. See Using FreeRDP and Remote Desktop for RDP Connections.

• Other software requirements

  Horizon Client also has certain other software requirements, depending on the Linux distribution you use. Allow the Horizon Client installation wizard to scan your system for library compatibilities and dependencies.

  Note: To enable connections to the Horizon Cloud Service - next-gen portal in non-private mode, ensure that a Secret Service package and the libsecret package are installed on the Linux client system. Since some thin client distributions do not support Secret Service, such thin client users can only connect to the Horizon Cloud Service - next-gen portal in private mode.

  The following list of requirements pertains only to Ubuntu distributions.

  • libudev.so.0

    Note: libudev0 is required to run Horizon Client. By default, libudev0 is not installed in some systems.

  • To support idle session timeouts: libXss.so.1.

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