Switch between RDP session and ThinOS client desktop
After you start RDP sessions with the Default on screen x option, and you want to switch back to the ThinOS client desktop
using Ctrl + Alt + Down key combinations, the design is as follows:
● Scenario 1: When the mouse cursor is located in an RDP session—In this scenario, if you press Ctrl + Alt + Down and
select the user to log in to ThinOS, only the session with the mouse cursor is minimized and ThinOS desktop is displayed on
the screen. Other RDP sessions remain unchanged.
● Scenario 2: When you start an RDP session on the primary display with Default on screen x—In this scenario,
ensure that the RDP session on primary display has the mouse cursor. To switch back to the ThinOS desktop screen, press
Ctrl + Alt +Down and select the user to log in to ThinOS.
● Scenario 3: When you press Ctrl + Alt + Down and select the System Information window—In the scenario, the
window is displayed on the screen irrespective of the cursor position.
● Scenario 4: When you want to display the Connect Manager window—In this scenario, you must minimize the RDP
session and open the ThinOS client desktop screen where the Connect Manager is located. Press Ctrl + Alt + Down and
select Connect Manager.
Secure RDP
The default behavior does not allow connection to the server when the ThinOS RDP client fails to verify the server certificate. A
security message is displayed indicating the failure. The following are the user INI parameters that can be used:
● securitymode=high—a security message is displayed and the user is not allowed to connect to RDP.
● securitymode=Warning—a security message is displayed but the user is allowed to connect to RDP.
● securitymode=Low—the user is allowed to connect to RDP and no security message is displayed.
Features of RDP protocol
Remote Desktop Protocol (RDP) is a network communications protocol developed by Microsoft that enables you to remotely
access virtual desktops and applications. This section describes the functionality of ThinOS over RDP protocol.
Using multi-monitors in RDP session
This section is applicable to Wyse 5070 thin client. ThinOS supports multiple-monitor display to launch RDP desktops on each
monitor.
User scenario:
1. Connect multiple monitors to ThinOS device.
2. In the Display Setup dialog box, disable Mirror Mode, and configure the display layout.
3. Launch an RDP desktop with full screen.
All data described in the following table is based on virtual machine without RemoteFX/vGPU enabled configuration.
