Linux Virtual Delivery Agent

What’s new

What’s new in 2311

Support for SUSE 15.5 and Debian 11.7

The Linux VDA now supports SUSE 15.5 and Debian 11.7. For more information, see System requirements.

HDX adaptive throughput

The Linux VDA now supports HDX adaptive throughput. The feature intelligently fine-tunes the peak throughput of ICA sessions by adjusting output buffers and results in an enhanced user experience. For more information, see the HDX adaptive throughput article.

AOMedia Video 1 (AV1) support

This release introduces a new codec, AV1 that lets you receive higher quality images at the same bandwidth utilization and higher FPS on lower bandwidths. AV1 uses a lower bandwidth per frame when compared to H.264 / H.265. For more information, see Graphics configuration and fine-tuning.


To use HDX 3D Pro with an NVIDIA GPU, you must install an NVIDIA graphics driver version that supports NVIDIA Capture SDK version 8. For more information, see the NVIDIA Capture SDK documentation.

Graphics status available in the system tray

Session users can now view the graphics status by clicking the system tray icon in their sessions.

For more information, see System tray.

Support for multiple audio devices (preview)

This release introduces an audio redirection feature. The feature allows multiple audio devices on the client machine where Citrix Workspace app is installed to be redirected to the remote Linux VDA session.

With the feature enabled:

  • All local audio devices on the client machine are displayed in a session. Instead of CitrixAudioSink (audio output) or CitrixAudioSource (audio input), the audio devices appear with their respective device names. You can select an audio device in an app in a session or use the default audio device during a session which is also the default audio device of the client machine. If necessary, you can change the default audio device from the system settings of the client machine. After the default audio device of the client machine is updated, the new device appears as the default audio device in the session.
  • Audio devices within sessions update dynamically when you plug in or remove one.

For more information, see Support for multiple audio devices.

Token-based enrollment (preview)

You can now enroll non-domain-joined VDAs with a machine catalog and authenticate these VDAs to the Citrix Cloud control plane using a token file.

The token-based enrollment is best suited for the use cases where you prepare machines (whether physical or virtual) on your own using non-Citrix provisioning technology. It offers the following benefits:

  • Eliminate the need to install and maintain Cloud Connectors.

  • Remove the AD dependency for user and machine authentication, enabling authentication for non-domain-joined machines.

For more information, see Create a non-domain-joined Linux VDA using easy install (preview).

Easy install enhancements

We have refactored and simplified the easy install feature to improve your experience. You can now:

  • Create non-domain-joined VDAs using easy install. This feature is in preview. For more information, see Create a non-domain-joined Linux VDA using easy install (preview).
  • Run the easy install script ( through all or specific modules. For instructions on modular execution, run -h to check the help information where examples are provided. For more information on, see the section of the Create domain-joined VDAs using easy install article.

  • Have a better understanding of the ctxinstall.conf.tmpl file where variables are grouped according to use cases.

Linux VDA data collection program

You now automatically participate in the data collection program after installing the Linux VDA. The data collection program collects statistics and usage data and sends the data to Citrix Analytics to help improve the quality and performance of Citrix products. To disable the program and view more details, see Linux VDA data collection program.

New metrics available for Linux sessions

This release adds two new metrics for Linux sessions in Citrix Director and Monitor:

  • ICA latency

    ICA Latency is basically the network latency. This metric indicates if the network is sluggish.

  • Policies

    All policies that are in effect for the current session are displayed on the Policies tab in the Session Details view.

For more information, see Linux VM and Linux session metrics.

Enhanced EDT congestion control is now generally available

A new congestion control algorithm is introduced to optimize the Enlightened Data Transport (EDT) protocol. This implementation allows EDT to achieve higher throughput and reduce latency for an enhanced user experience. This feature is enabled by default. For more information, see Adaptive transport.

Rendezvous V2 by default

The Rendezvous Protocol is disabled by default. When the Rendezvous Protocol is enabled, Rendezvous V2 instead of V1 takes effect.

EDT MTU discovery is now enabled on the VDA by default

MTU discovery allows EDT to automatically determine the Maximum Transmission Unit (MTU) when establishing a session. Doing so prevents EDT packet fragmentation that might result in performance degradation or failure to establish a session. For more information, see Adaptive transport.

What’s new in earlier releases
