CTXGFX graphics process auto recovery

When a graphics subsystem failure occurs, Linux VDA automatically restores Thinwire rendering and user input (keyboard and mouse), allowing the session to continue uninterrupted.

Cross-session clipboard sharing (General Availability)

Cross-session clipboard data sharing, previously available as a tech preview, is now generally available. Previously, this feature was enabled and configured via a registry key. Starting in this release, this feature is controlled by a clipboard sharing scope and clipboard write allowed formats Group Policy, giving administrators a centralized, policy-driven way to specify which clipboard formats are permitted.

Relocated Unix domain socket files

Unix domain socket files previously created in $HOME or /tmp are now placed in /run/user/<uid> (the systemd runtime directory), with automatic fallback to /var/xdl/user/<uid> or /var/xdl/user. Sessions on read-only or NFS-mounted home directories no longer fail. When sockets reside in /run/user/<uid>, systemd automatically cleans them up when the session ends; sockets in fallback directories are not automatically cleaned up.

OS lock screen control

Linux VDA now supports administrator control of the OS-level desktop lock screen via a registry key. OS lock screen by default is disabled. To enable the OS lock screen:

#/opt/Citrix/VDA/bin/ctxreg create -k "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix\Login" -t "REG_DWORD" -v "EnableOsLockScreen" -d "0x00000001" --force
