Refer to the sections below to set up and configure a Linux Server for desktop delivery:

  1. Required Packages

  2. Getting Ubuntu OS Image

  3. Ubuntu OS VM Installation

  4. Post OS Installation Configuration

  5. Offline Package Installation

  6. Configurations and Environment Preparation

  7. Troubleshooting

Required Packages

A deployment of Linux-based desktops will require the following packages to be installed and configured:

  • Linux-based Dedicated Virtual Desktops

    1. Linux OS ISO for OS Installation

    2. Accops DVM Tools Dependency Packages:

      • Must have all the dependency package(s) for HyWorks deployments

    3. Optional - HyWorks DVM Tools for Linux: If the dependency package does not contain the latest HyWorks DVM Tools for Linux

Step#1: Getting Ubuntu OS

For Ubuntu-based dedicated desktops: Download any of the following supported ISOs from their official websites. Below is the list of supported Ubuntu-based Linux OSes:

Note

  • v4.0 RHEL Releases are not yet done. It is targeted to be released soon and made available as GA.

  • Ubuntu 24.04.0/1, 22.04.0/1 (Legacy Kernel)

  • XUbuntu 24.04.0/1, 22.04.0/1 (Legacy Kernel)

Note

  • GNOME serves as the default desktop environment in Ubuntu.

Important

  • HyWorks only supports the listed Linux distributions and OS versions; installing or using any other version or flavor may cause issues.

  • HyWorks only supports Operating System versions with a point 0 or 1 that use a non-HWE (Hardware Enablement) kernel; versions with the HWE kernel are not supported.

  • Ensure you install only version 0 or 1; installing any other version may cause package or tool installation issues, which could lead to app or desktop delivery failures.

Step#2: Brief Ubuntu OS Installation Process

For Linux-dedicated VDI deployments, Ubuntu or CentOS can be installed as a VM on hypervisors supported by HyWorks. Follow the steps included below to install the Ubuntu-GNOME ISO that was downloaded in Step# 1 on any hypervisor:

  1. After booting the VM with the installation media (the image downloaded in step 1), select the Install Ubuntu-GNOME option.

  2. Choose the language for the setup UI.

  3. Do not change the default option on the Preparing to install Ubuntu screen.

  4. Select Installation Type: Erase disk and install Ubuntu GNOME.

  5. Select the Time zone and Keyboard layout.

  6. Enter the username, machine, and password in the fields for Who are you?

  7. Once installation is complete, restart the VM.

  8. When the VM reboots, a prompt to remove media will be displayed. Press Enter and follow the instructions displayed on the screen.

Step#3: Post OS-Installation Configurations

Follow the steps provided in the Post-OS-Installation Configurations section for post-OS installation configurations.

Step#4: Accops Assistive Package Installation

Follow the steps provided in the Accops Assistive Package Installation section to install offline packages on an Ubuntu server.

Step#5: Configurations and Environment Preparation

Follow the steps provided in the Basic Configuration for Environment Preparation section for basic configuration steps for authentication.
