Description

Desktop launches and then disappears. Once the machine is rebooted sometimes it works and sometimes it does not work even after reboot. Problem started after upgrading from VDA 2209/2311 to VDA 2402.

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

 Setting the following registry key resolved the issue:

HKLM\SOFTWARE\Citrix\Graphics 

GfxLoadTimeout  DWORD
Value: 40000

 


Problem Cause

Citrix Graphics Manager fails to initialize successfully. CDF traces indicate that when trying to load Twconsumer.dll, there was some delay at the OS level and this resulted in a timeout leading to the issue.
