Settings tab is not available in the display control panel of a Horizon View desktop in local mode when the agent is installed with PCoIP protocol (1020809)

  • 33 Ratings

Symptoms

  • The Settings tab is missing or grayed out inside the display control panel of a local mode desktop that has the PCOIP protocol installed.
  • You cannot see the Settings tab in a local mode desktop that has the PCOIP protocol installed.
  • The Settings tab may be visible, but you cannot make changes.

Cause

Toggle Display Settings Control determines if the Settings tab in the Display control panel displays when a client session uses the PCoIP display protocol. This setting is enabled (to hide the settings tab) by default.

When connected to a virtual desktop, this setting may be disabled to ensure proper resolution settings so the resolution always adapts to the host's screen resolution. Using the host's screen resolution is important if you run the View desktop in full screen mode or if you use multiple monitors.
 
This may cause an issue when working with a virtual machine in local mode.

Resolution

To be able to work with a virtual machine in local mode. You must re-enable the setting by editing the Group Policy Object (GPO) settings in the vdm_agent.adm template. The View ADM template files are installed in the install_directory\VMware\VMware View\Server\extras\GroupPolicyFiles directory on your View Connection Server host.

Note: Adjusting the display properties from the View virtual machine is not supported. Display changes should be made from the client machine. Changing the display setting from the View virtual machine can cause display issues. Only apply this setting when using an offline View local mode virtual machine.

To re-enable settings:
  1. Log in to the Domain Controller that provides domain authentication services for your VMware View environment.
  2. Click Start > Programs > Administrative Tools > Group Policy Management. This opens the Group Policy Management Console.
  3. Select the Group Policy you have assigned to the Organizational Unit where your virtual desktops are members.
  4. Right-click the policy and click Edit.
  5. Navigate to the configuration settings:

    In Windows Vista, or Windows Server 2008 or later - Navigate to Computer Configuration > Administrative Templates > Classic Administrative Templates (ADM) > VMware View Agent Configuration > Agent Configuration, edit the settings under Toggle Display Settings Control to Disabled to manage this property in Windows.

    In Windows XP or Windows Server 2003 - Navigate to Computer Configuration > Administrative Templates > VMware View Agent Configuration > Agent Configuration, edit the settings under Toggle Display Settings Control to Disabled to manage this property in Windows.

  6. Close the Group Policy Object Editor.
  7. Log out of the Domain Controller.
  8. Log in to the virtual desktop.
  9. Click Start > Run, type gpupdate/force, and click OK.

    Note: This forces the application of any computer or user policies that have been assigned to the virtual desktop.

  10. Log out of the guest operating system and then log in again.

    Note: If the change does not take effect, you may need to reboot the virtual machine.

  11. If the virtual machine is a template virtual machine, shut down the virtual machine and convert it to a template. See Convert a Virtual Machine to a Template in the vSphere Client section in the VMware vSphere 5.1 Virtual Machine Administration Guide.
  12. If the virtual machine is a linked clone parent image, shut down the virtual machine, and take a snapshot.

    Note: These settings can be changed inside a linked clone virtual machine or you can make changes in the master image, take a snapshot, and deploy virtual machines.
     
    If editing the GPO does not resolve the issue, verify that the value of this registry key is set to 0. If it is not, set it to 0:
    1. Click Start > Run, type regedit, and click OK. The Registry Editor window opens.
    2. Navigate to the registry key:

      • For Windows XP - HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\NoDisplaySettingsPage
      • For Windows 7 - HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\NoDispCPL

    3. Set the value to 0.
