Dell ThinOS 2211, 2208, and 2205 Release Notes

Citrix Workspace app updates

Citrix Workspace App package version is updated to 22.9.0.21.3.

Supports virtual display layout

From ThinOS 2211 and Citrix Workspace App 2209, virtual display layout on VDA is supported. The virtual display configuration interface helps you to define a virtual display layout per session monitor on the VDA, in a live session. This feature allows you to split each session monitor independently into multiple virtual monitors. You can split the session into eight virtual monitors on the remote desktop. Also, you can update the session primary monitor and DPI settings for the displays.

The virtual display configuration is stored per user per client device, which has persisted across session resize, session disconnect or reconnect, and session logoff or login. The configured virtual display layout reset occurs on a session resize and change in the number of session monitors.

Follow these steps to configure your virtual display layout on VDA:

1. Right-click the graphics status indicator icon from the system tray and select Configure virtual displays.

   The virtual display configuration interface is launched.

2. Right-click a virtual display to mark it as the primary monitor.
3. Use the DPI drop-down list to set a preferred scaling factor for the virtual display.

   You can draw horizontal or vertical lines to separate the screen into virtual monitors. The screen is split according to specified percentages of the session monitor resolutions.

4. After defining a virtual display layout, click OK to save the layout, or Cancel to discard the changes.

   Use Reset to undo the configuration and restore the original layout.
