Compatibility Overview

Some features added to new releases of the Remote Workstation Card Software require firmware upgrades on the PCoIP Remote Workstation Card and/or PCoIP Client. We recommend that you install the PCoIP Remote Workstation Card Software release that corresponds to the corresponding version of Remote Workstation Card firmware.

Software Client Limitations

  • USB devices connected to Teradici Software Client hosts are not supported when connecting to Remote Workstation Cards or Remote Workstation Card Agents.

  • Users cannot disable the local cursor feature while connected to the PC/workstation from a soft client.

Graphic card temporal dithering

Temporal dithering is a technique employed by some graphics cards to simulate colors that they cannot natively display by rapidly changing the colors of pixels, thus tricking the eye into seeing “in-between” colors. During PCoIP remote sessions, temporal dithering can cause extremely high bandwidth utilization because the rapidly changing pixels force the PCoIP protocol to constantly deliver large screen updates to the remote desktop. Temporal dithering should be disabled on workstation graphics cards supporting PCoIP sessions. Consult your graphics card documentation or contact the card vendor for details on disabling temporal dithering. Knowledge Base article KB 1087 on the Teradici Support Site also contains information on disabling temporal dithering on some graphics cards.

Requirements

Before installing this release of PCoIP Remote Workstation Card Software, ensure the following requirements are met:

  • Installation from Host PC

    The Linux host operating system administrator must not install Remote Workstation Card Software from a software client as functionality of the mouse and keyboard will be lost.
  • Compatible host and client: The Remote Workstation Card and PCoIP client used with Remote Workstation Card Software must be the same version or include the immediate preceding version.

  • Enabled Host Driver Function: Ensure the Host Driver Function is enabled on the Remote Workstation Card. See section PCoIP Remote Workstation Card Software Installation.

  • Supported Linux distribution: Remote Workstation Card host computer must be operating a supported Linux distribution. Remote Workstation Card Software might work on other Linux distributions, but Teradici makes no guarantees.

    • CentOS 7.7 (kernel 3.10.0-1062.el7), GNOME/KDE

    • RHEL 7.5 (kernel 3.10.0-229), GNOME/KDE

  • Sudo Permissions: The Linux host operating system administrator installing this package must be able to execute sudo commands.

  • Correct xrandr version: The workstation should have xrandr version 1.2 or later installed. If an earlier version is installed, the Remote Workstation Card Software cannot activate the client topology settings at the start of a session and users might encounter problems where the client cursor and keyboard do not work.

  • Correct kernel for Wacom tablet users: Wacom tablet users may have to update the Linux kernel Wacom driver. Please see About Local Tablet Driver for further details.
