The Linux PC or laptop on which you install Horizon Client, and the peripherals it uses, must meet certain system requirements.

Note:

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 View 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.

Note:
  • 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.

OpenSSL requirement

Horizon Client requires a specific version of OpenSSL. If you have Horizon Client 3.4 or later, the correct version is automatically downloaded and installed. If you have Horizon Client 3.2 or earlier, if you do not install the correct version of OpenSSL, the client might not start, might exit unexpectedly, or might not be able to connect to the server. The client might also be vulnerable to security bugs that exist in the older versions of libraries that are in use.

Table 1. Open SSL Requirements for Specific Versions of Horizon Client

Client Version

Requirement

Horizon Client 4.0

OpenSSL 1.0.2f or later. For your convenience, it you do not have the correct version of OpenSSL, the Horizon Client installer will download and install the required version of OpenSSL

Horizon Client 3.4 and 3.5

OpenSSL 1.0.1m or later. For your convenience, it you do not have the correct version of OpenSSL, the Horizon Client installer will download and install the required version of OpenSSL

Horizon Client 3.2

OpenSSL 1.0.1i or later.

Important:

If you download the source code for OpenSSL 1.0.1i from the OpenSSL Web site or some other site, compile, and install it, you might get libraries with the extension 1.0.0 or 1.0.1i, but Horizon Client looks for libraries with the extension 1.0.1. Specifically, the client looks for files named libssl.so.1.0.1 and libcrypto.so.1.0.1 in system's library path. To work around this issue, you can create a symbolic link by linking libssl.so.1.0.1 to libssl.so.1.0.1i or libssl.so.1.0.0, as appropriate, and linking libcrypto.so.1.0.1 to libcrypto.so.1.0.1i or libcrypto.so.1.0.0.

Horizon Client 3.1

OpenSSL 1.0.1h

View Connection Server, Security Server, and View Agent

Latest maintenance release of View 5.3.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) View servers.

Display protocol

  • VMware Blast (requires Horizon Client 4.0 or later and Horizon Agent 7.0 or later)

  • PCoIP

  • RDP

Screen resolution on 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

  • For Ubuntu 12.04, use rdesktop 1.7.0.

Software Requirements for FreeRDP

If you plan to use an RDP connection to View 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.

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

  • To support Flash URL redirection: libexpat.so.1. (The libexpat.so.0 file is no longer required.)

  • To support USB redirection and Real-Time Audio-Video: libudev0.

    Note:

    By default, libudev0 is not installed in Ubuntu 14.04.

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