The Linux VDA now supports the following Linux distributions:
- Debian 12.12
- Debian 13.1 (Note: MCS provisioning is currently not available due to Samba limitation in Debian 13; HDX 3D pro is currently not available due to GPU driver limitation)
- RHEL 9.7
- Rocky Linux 9.7
- SUSE Linux Enterprise Server 15.7
For more information about supported Linux distributions, see System requirements.
Support RHEL & Rocky Linux 10 （Preview）
Description of the Feature - LinuxVda needs to be continuously supported along with the release of linux distributions. Now, the official has provided the download of the RHEL 10.0 version on May 20th. In the release-2511 version and later, we will add the support for rhel/rocky 10.
Benefits - Modify the version check of rhel/rocky in easyinstall and xdping. From now on, the installation of the rhel/rocky series and the execution of xdping will no longer check minor versions. The support will be subject to the documentation released by Citrix.
Support for RHEL 10 （Preview)
The Linux VDA now supports the following Linux distributions:
- RHEL 10
Supported Linux distributions, Xorg versions, and desktop environments
For a matrix of the Linux distributions, Xorg versions, and desktop environments that this version of the Linux VDA supports, see the following table. For more information, see XorgModuleABIVersions.
AOT Log Collection and Upload
Starting with this release, Linux VDA supports collecting and uploading AOT logs to a centralized log server, enabling improved troubleshooting across Citrix components.
For more details, refer to AOT Log Collection
Cross session clipboard exchange support (preview)
This feature involves the ability to copy content from one session to another through the common Client host but without actually saving that content on the client host machine. The tech-preview release of this feature will obtain the list of formats to be tunneled through the CrossSessionClipboard from a VDA RegKey. The value is a list of formats to be tunneled across CSC.
Example:
/opt/Citrix/VDA/bin/ctxreg create -k
"HKLM\System\CurrentControlSet\Control\Citrix\wfshell\Virtual Clipboard\CrossSessionClipboard" -t
"REG_MULTI_SZ" -v "CrossSessionFormats" -d
"CF_TEXT\0CF_BITMAP\0CF_DIB\0CF_UNICODETEXT\0CFX_FILE\0\0" —force
Enhanced TCP Congestion Control
Starting with this release, an enhanced TCP Congestion Control is provided for improving in session video and audio performance under high latency network. It’s by default off, the TCP congestion control method remains system default.
opt/Citrix/VDA/bin/ctxreg create -k "HKLM\System\CurrentControlSet\Control\Terminal Server\Wds\icawd\HdxPerformance" -t "REG_DWORD" -v "EnhancedTcpCongestionEnabled" -d "0x00000001" —force
Support disabling optional Linux VDA services
This feature allows optional Linux VDA services to be disabled via /etc/xdl/disablelist.conf, giving it higher priority than policy and local registry settings.
To disable a service, uncomment it from the configuration file after installing Linux VDA package.
Support caching the CGS FQDN IP address
The Linux VDA Rendezvous V2 now supports caching the CGS FQDN IP address after the first successful DNS lookup. If DNS becomes temporarily unavailable, connections can fall back to the cached IP. This feature is disabled by default.
To enable it, run /opt/Citrix/VDA/bin/ctxreg create -k "HKLM\Software\Citrix\Ica\EdgeNodeCache" -t "REG_DWORD" -v "EnableDNSCache" -d "0x00000001" —force
Support FAS info transmission through FAS launch ticket v2
This feature enables transmission of FAS server FQDN and port through the FAS launch ticket v2. The Linux VDA decodes this information directly from the ticket, eliminating the need for a registry entry on the VDA
Improve user experience with TCP transport for audio redirection
Starting with 2511 in Tech Preview, audio quality enhancer is also available for connections over reliable transport (i.e. TCP and EDT-Reliable). Under poor network conditions, both audio playback and recording will have a smoother experience with reduced latency.
HDX Screen Sharing improvements
HDX Screen sharing is available for shadowing using Citrix Director for Citrix Virtual Apps and Desktops on-premises installations and Citrix Monitor for Citrix Cloud deployments. HDX Screen sharing is the new method for shadowing and provides a native, low latency alternative to the current shadowing. HDX Screen sharing for Director is available for all VDAs, including non-domain joined and Entra ID joined VDAs. Refer to this link for the details: TODO: the link to director page about the feature.
Support Service Continuity for connectionless workloads
Service Continuity enables end users to maintain access to business critical workloads during service disruptions. With this new feature, Service Continuity now supports Linux dedicated VDI workloads in connectorless resource locations. This includes AD joined and Non-domain joined workloads. For more information, please refer to Service Continuity.
PVS IPv6 support
This release supports pure IPv4, pure IPv6, and dual-stack deployments that use overlapping IPv4 and IPv6 networks. For details, please refer to the documentation IPv4/IPv6 supportThis release supports NVMe disks for vmware.
Audio Quality Enhancer for reliable transport (preview)
Starting with 2511 in Tech Preview, audio quality enhancer is also available for connections over reliable transport (i.e. TCP and EDT-Reliable). Under poor network conditions, both audio playback and recording will have a smoother experience with reduced latency.
