Faster LDAP queries

In addition to querying each LDAP server in polling mode, the Linux VDA can now query LDAP servers in a multi-domain forest concurrently. To enable the faster LDAP queries, enable Global Catalog on a domain controller and specify the relevant LDAP port number as 3268. For information about how to specify LDAP servers and LDAP ports, see the CTX_XDL_LDAP_LIST variable description in the Linux VDA installation article based on your distribution.

Custom FAS port

Previously, the Linux VDA was hardcoded to communicate with FAS servers over port 80. Starting with this release, you can customize the FAS port on the Linux VDA side through CTX_XDL_FAS_LIST in the ctxsetup.sh. For more information, see the Linux VDA installation article based on your distribution.

What’s new in 2204

Version 2204 of the Linux VDA includes the following new features and enhancements:

Hardware encoding extended to selective codec

Previously available only for the entire screen, H.264 hardware encoding now supports selective use for actively changing regions. This feature offloads CPU video compression consumption to hardware and improves image quality and the number of frames per second (FPS). For information on how to enable this feature, see Graphics configuration and fine-tuning.

Support for logon with a temp home directory

Starting with this release, you can specify a temp home directory for cases where the mount point on the Linux VDA fails. With a temp home directory specified, a prompt shows during a session logon when the mount point fails. User data is then stored under the temp home directory. For more information, see Logon with a temp home directory.

SOCKS5 proxy support for Rendezvous HDX traffic

The Linux VDA now extends SOCKS5 proxy support for establishing Rendezvous connections. For more information, see Rendezvous V1 and Rendezvous V2.

What’s new in 2203

Version 2203 of the Linux VDA includes the following new features and enhancements:

Full support for Rendezvous V2

When using the Citrix Gateway service, the Rendezvous protocol allows traffic to bypass the Citrix Cloud Connectors and connect directly and securely with the Citrix Cloud control plane.

There are two types of traffic to consider: 1) control traffic for VDA registration and session brokering; 2) HDX traffic.

Rendezvous V1 allows for HDX traffic to bypass the Cloud Connectors, but it still requires Cloud Connectors to proxy all control traffic for VDA registration and session brokering.

Standard AD domain joined machines and non-domain joined machines are supported for using Rendezvous V2 with single-session and multi-session Linux VDAs. With non-domain joined machines, Rendezvous V2 allows for both HDX traffic and control traffic to bypass the Cloud Connectors.

For more information, see Rendezvous V2.

Easy install GUI is now available

Previously, you could only operate a command line interface for using easy install. This release offers an easy install GUI that guides you through the following operations:

• Check the system environment
• Install dependencies
• Join the VDA to a specified domain
• Configure the runtime environment

To use the easy install GUI, run the /opt/Citrix/VDA/bin/easyinstall command in the desktop environment of your VDA. For more information, see the Interactive mode section of the Quick installation by using easy install (Recommended) article.

HDX graphics improvement

Thinwire can now improve the numbers of Frames Per Second (FPS) by parallelizing certain tasks, with the overhead of slightly higher overall CPU consumption. This feature is disabled by default. For more information, see the Parallel processing section of the Configure graphics article.
