Description
After installing the VDA on a device with a GPU, and configuring for Remote PC Access, customers may notice that monitors attached to the device are not blanked out when a user is connected via ICA, and all activity is visible on both the remote and local displays.
Environment
Caution! Using Registry Editor incorrectly can cause serious problems that might require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Be sure to back up the registry before you edit it.
Resolution
NOTE: The Indirect Display Driver is not present on Virtual Delivery Agent 7.15, so customers will need to upgrade to Virtual Delivery Agent 1912 LTSR or the Current Release to benefit from this.
Add the following registry value on the Virtual Delivery Agent:
Key:
HKEY_LOCAL_MACHINE\Software\Citrix\Graphics\AdapterMerits
Value:
Name: CitrixIDD
Type: DWORD
Data: 3
This forces the Citrix Graphics stack to use the Citrix Indirect Display Driver instead of the default GPU driver for remote sessions.
