HDX screen sharing

Overview

The Linux VDA lets you share the screen of your virtual desktop with session users on other virtual desktops.

The following example walks you through the procedure of sharing a screen and viewing some else’s screen.

To share a screen:

1. In the notification area of your virtual desktop, click the screen sharing icon and select Share my screen.

   

2. Click Copy and Close.

   The current screen sharing code persists until you stop and restart sharing your screen.

   

   Tip:

   While you are sharing your screen, there is a red border around it, indicating that sharing is in progress.

3. Share the copied code with session users on other virtual desktops that you want to share your screen with.

4. To let a viewer control your screen, select Give control and then the viewer’s name. To stop giving control, clear the viewer’s name.

   

5. To stop sharing your screen, select Stop sharing my screen.

   

To view someone else’s screen:

1. In the notification area of your virtual desktop, click the screen sharing icon and select View someone else’s screen.

   

2. Enter the connection code of the screen that you want to view and then click Connect.

   

3. Wait for the screen sharer to accept your request. For example:

   

   Tip:

   • On the sharer side, the Linux system issues a notification of your request.
   • If the sharer does not accept your request within 30 seconds, your request expires and a prompt appears.

4. After the screen sharer accepts your request by clicking OK, the shared screen appears in your Desktop Viewer. You are connected as a viewer with an automatically assigned user name.

   

5. To request control over the shared screen, click the mouse icon in the upper left corner.

   Tip:

   • If the sharer does not accept your request within 30 seconds, your request expires.
   • Only one viewer is allowed to control a shared screen at a time.

   Click the mouse icon again to release control over the shared screen.

   

6. To disable display scaling or scale to the window size, click the icon next to the mouse icon.
