About this release

What’s new

What’s new in 1906

Improved UI experience with latest webkit support

In earlier releases, the self-service UI required libwebkitgtk Version 1.0. Because Version 1.0 of the webkit has been deprecated, most Linux distributions no longer support or require it. Going forward, Citrix Workspace App for Linux is requires libwebkit2gtk (2.16.6+).

libwebkit2gtk has the following advantages:

  • Improved UI experience. webkit2gtk is compatible with the browser content redirection feature. Use webkit2gtk Version 2.24 or later for an even better YouTube viewing experience.
  • webkit2gtk Version 2.16.6 and later improves the sign-in experience with respect to the user interface and the time it takes to sign in.
  • The app works better with newer Linux distributions and provides with the latest webkit security fixes.


webkit2gtk is not available on some Linux distributions. As a workaround for those distributions, consider the following options:

  • Build webkit2gtk from the source before installing Citrix Workspace app 1906.
  • Download the web package from the Downloads page page. Only web launches are supported in this package.
  • Move to a later Linux distribution that supports webkit2gtk 2.16.6 or later.

Language support

Citrix Workspace app for Linux is now available in the Dutch language.

VDA keyboard layout

The VDA keyboard layout feature helps you use the VDA keyboard layout regardless of the client’s keyboard layout settings. It supports the following types of keyboard: PC/XT 101, 102, 104, 105, 106. To use the feature, modify the KeyboardLayout=(Server Default) section of the wfclient.ini file and relaunch the session.

Secure SaaS with embedded Citrix Secure Browser [Experimental]

Secure access to SaaS applications provides a unified user experience that delivers published SaaS applications to the users. SaaS apps are available with single sign-on. Administrators can now protect the organization’s network and end-user devices from malware and data leaks by filtering access to specific websites and website categories.

Citrix Workspace app for Linux support the use of SaaS apps using the Access Control Service. The service enables administrators to provide a cohesive experience, integrating single sign-on, and content inspection.


To launch the SaaS applications, ensure libgtkglext1 package is available.

Delivering SaaS apps from the cloud has the following benefits:

  • Simple configuration – Easy to operate, update, and consume.
  • Single sign-on – Hassle-free log on with single sign-on.
  • Standard template for different apps – Template-based configuration of popular apps.

Note: SaaS with Citrix Browser Engine is supported only on x64 and x86 platforms and not on ArmHardFloatPort (armhf) hardware.

For information on how to configure SaaS apps using Access Control Services, see the Access Control documentation.

For more information about SaaS apps with Citrix Workspace app, see Workspace configuration in in Citrix Workspace app for Windows documentation.

What’s new in 1903

Cryptographic update

This feature is an important change to the secure communication protocol. Cipher suites with the prefix TLS_RSA_ do not offer forward secrecy and are considered weak. These cipher suites were deprecated in Citrix Receiver version 13.10 with an option for backward compatibility.

In this release, the TLS_RSA_ cipher suites have been removed entirely. Instead, this release supports the advanced TLS_ECDHE_RSA_ cipher suites. If your environment is not configured with the TLS_ECDHE_RSA_ cipher suites, client launches are not supported due to weak ciphers. This release supports 1536-bit RSA keys for client authentication.

The following advanced cipher suites are supported:

  • TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 (0xc030)
  • TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384 (0xc028)

For more information see, cipher suites.


From version 1903 and later, DTLS is supported from Citrix Gateway 12.1 and later. For information on DTLS supported cipher suites for Citrix Gateway, see Support for DTLS protocol

Bloomberg audio redirection

This feature allows the use of Bloomberg v4 audio interfaces across multiple sessions. The audio from the sessions now goes through the optimized channel to the Bloomberg interface. The fingerprint interface is redirected to a single session as before.


By default, this feature is disabled for the x86, x64, and for ARMHF platforms.

For more information on how to configure Bloomberg audio redirection, follow the steps mentioned under selective redirection.

Sign-on page

This release introduces a new sign-on page in the self-service user interface.

Disconnect time

This release addresses issues that help to significantly improve the disconnect time.

What’s new in 1901

Support for Citrix Analytics

Citrix Workspace app for Linux is instrumented to securely transmit logs to Citrix Analytics when certain events are triggered by the app. The logs are analyzed and stored on Citrix Analytics servers when enabled. For more information about Citrix Analytics, see Citrix Analytics.

Workspace launcher with Citrix Gateway

Citrix introduced Workspace launcher (WebHelper) in version 1809. In version 1901, Citrix Workspace launcher works not only with direct connections to StoreFront, but also through Citrix Gateway. This feature helps to launch the ICA file automatically and to detect the Citrix Workspace app installation.

Logging enhancements II

Logging enhancements II is an extension of the Logging enhancements and Better logging features. The feature introduces support for logging for many modules and simplifies the process of collecting logs. It helps users troubleshoot, and - in cases of complicated issues - facilitates support by providing detailed logs.

For information about enabling logging, see Enabling logging.

Keyboard layout synchronization between client and VDA

Previously, the keyboard layouts on the Windows or Linux VDA and on the client device were synchronized manually. For example, when the keyboard layout changed from English to French on the client device but not on the VDA, key mapping issues could occur and persist until the keyboard layout on the VDA was changed to French too.

Starting with this release, Citrix is addressing the issue by automatically synchronizing the keyboard layout of the VDA with that of the client device. Anytime the keyboard layout on the client device changes, the layout on the VDA follows automatically.


This feature requires version 7.16 or later of the VDA.

For more information, see Keyboard layout synchronization.

What’s new in 1810

This release addresses a number of issues that help to improve overall performance and stability.

What’s new in 1809

Connecting this version of Citrix Workspace app for Linux to Citrix Workspace services is an experimental feature.

Introducing Workspace launcher

Previously, the browser plug-in provided along with Citrix Workspace app for Linux enabled users to launch published desktops and applications. This plug-in was based on the Netscape Plugin Application Programming Interface (NPAPI).

Mozilla Corporation has announced that NPAPI support is deprecated as of version 52 of the Firefox browser. Other browsers, too, have deprecated support for NPAPI.

As a solution, Citrix is introducing Workspace launcher (WebHelper). To enable this feature, configure StoreFront to send requests to Workspace launcher in order to detect the Citrix Workspace app installation.

For information about configuring StoreFront, see Solution – 2 > a) Administrator configuration in Knowledge Center article CTX237727.


Citrix Workspace launcher currently works only with direct connections to StoreFront. It is not supported in other cases such as connections through Citrix Gateway.

Disabling new workspace web UI mode

When you launch the Citrix Workspace app for Linux using self-service executable file from third-party thin client vendors, the application can become unresponsive due to 100% CPU utilization.

As a workaround, to switch back to the old UI mode:

  1. Remove cached files by using the command:

    rm -r ~/.ICAClient

  2. Go to $ICAROOT/config/AuthManconfig.xml file.
  3. Change CWACapableEnabled key value to false.
  4. Launch Citrix Workspace app for Linux. Observe that the self-service executable file loads the old UI.

Known issues

Known issues in 1906

  • After disconnecting the ICA session, the wfica process may exit after a couple of minutes . This is because, the wifca process tries to contact the network during exit. [RFLNX-3025]
  • When you connect to a PNAgent store, not all the subscribed resources appear when you use the command ./util/storebrowse -S. [RFLNX-2944]
  • When using Skype, occasionally a webcam might not establish video when you log on consecutive times. As a workaround, close and restart the Skype session. [RFLNX-2897]
  • The DynamicCDM feature might not work on CentOS 7.6, and the USB flash disk is not mapped to the desktop session. [RFLNX-3117]
  • The first time launch of a session on an ArmHardFloatPort (armhf) device that is based on Raspbian GNU/Linux 8.0 (jessie) might fail. The subsequent launches succeed. [RFLNX-3211]
  • Citrix Workspace app for Linux does not support 32-bit cursors. If a 32-bit cursor is used on the VDA, it appears as black. This issue has been observed in earlier releases too. [RFLNX-1296]
  • ICA launch might fail on Fedora 29/30. As a workaround, follow the steps:

    1. Install openssl10 by using the command sudo yum install compat-openssl10.x86_64
    2. Set the environment variable in ~/.bashrc to load for every session. This action points to the older libcrypto library. export LD_PRELOAD=/lib64/libcrypto.so.1.0.2o


The app works fine in X.Org server as compared to the Wayland compositor. For distributions that have Wayland as the default graphics protocol, uncomment either of the following:

WylandEnable=false in /etc/gdm/custom.conf or /et/gdm3/custome.conf. Log off and log on to point to the X.Org server.

Known issues in 1903

  • When using Fedora 29 and later, the Citrix Workspace app for Linux exits unexpectedly with an error message “SIGSEGV”. This issue occurs because Fedora Version 29 and later are not currently supported due to incompatibility in the libidn package provided by the operating system. [LD0705]

  • The Citrix Optimization SDK package contains in incorrect version of the UIDialogLibWebKit.so. As a workaround, perform the follow the steps:

  1. Download Citrix Optimization SDK package version 18.10 from the Downloads page.

  2. Go to the path CitrixPluginSDK/UIDialogLib/GTK:

    cd CitrixPluginSDK/UIDialogLib/GTK

  3. Delete all the object files:

    rm -rf *.o

  4. Go to WebKit folder:

    cd ../WebKit

  5. Remove the existing UIDialogLibWebKit.so:

    rm -rf UIDialogLibWebKit.so

  6. Use the following command in the WebKit directory:

    make all

    The new UIDialogLibWebKit.so is generated.

  7. Copy the new library into the $ICAROOT/lib directory.
