Erratic mouse movement causes issues with VMware Horizon View 5.2 PCoIP connections (2060701)

  • 23 Ratings

Symptoms

  • When connecting to a VMware Horizon View desktop using the PCoIP protocol from a View Fat/Thick Client, the mouse movements appear jittery.
  • In the View PCoIP client log files, you see entries similar to:

Cause

This issue is caused by a third-party application running in the View desktop that is setting the cursor position to manual.

Resolution

To resolve this issue, disable cursor jumping in the Registry.

To disable cursor jumping:
 
Note: This procedure modifies the Windows registry. Before making any registry modifications, ensure that you have a current and valid backup of the registry and the virtual machine. For more information on backing up and restoring the registry, see Microsoft Knowledge Base article 136393.
    1. In the View desktop, click Start > Run, type regedit, and click OK. The Registry Editor window opens.
    2. Go to HKEY_LOCAL_MACHINE\Software\Policies\Teradici\PCoIP\pcoip_admin_defaults.
    3. Set pcoip.disable_cursor_jumping to 1.

      Note: If the value does not exist, right click and select New > DWORD (32-bit) Value and create the pcoip.disable_cursor_jumping value and set to 1.
    If you do not wish to make the change directly on the View desktop, you can implement the change on the associated parent image and recompose the effected pool. Another option is to set a GPO for this registry key and apply it to all effected View desktops. For more information on GPOs, see this Microsoft technote.
     
    Note: The preceding links were correct as of April 1, 2014. If you find the links are broken, provide feedback and a VMware employee will update the link.

    Impact/Risks

    Note:  For versions earlier than View 5.3, setting this registry key causes the pcoip_server process on the View desktop to crash when closing a session instead of shutting it down.
    This leaves some .dmp files on the disk that can take up space.

    Additional Information

    Note:  For more information on the location of the View log files, see Location of VMware View log files.
