Today, I had a small issue with a Manual Dedicated Horizon View 5.2 PCoIP Desktop Pool for access to a Management Windows 7 VM and I was scratching my head for a while trying to figure this one out.
Essentially, I could connect without any issues via the View Client to the Windows 7 desktop but only if I can the desktop in Windows -Large or Windows – Small.
If I expanded the desktop beyond a certain size or made it full screen, I had a black background (the pictures below look the same size, but i’m sure you get what I mean).
Large Desktop – Black
Troubleshooting Steps – (That Didn’t Work)
- Logged into the Windows 7 VM via RDP and rebooted.
- Logged into the Windows 7 VM and changed the screen resolution to 1920 x 1080
- Uninstalled View Agent & re-installed
- Uninstalled the vSGA Driver from Device Manager and the manually installed the driver from C:Program FilesCommon FilesVMwareDriversvideo_wddm
Troubleshooting Steps – (That Worked)
I found KB1018158 Configure PCoIP for use with View Manager which had most of the symptoms. I knew I had installed the VMTools then View Agent (correct order), and then I read further down the KB and discovered this:
Note: Do not reboot by clicking Shutdown > Restart in the virtual machine. PCoIP is dependent upon the appropriate amount of video memory being allocated to the virtual machine. Because this is a virtual hardware setting (that must be in place before the virtual machine starts up), it is applied as a change in the .vmx file. If the virtual machine has already been started, it is essential that this virtual machine be restarted so that the .vmx file is re-read and the changes are used. Using the Shutdown > Restart option inside the virtual machine does not force the .vmx to be re-read, as this does not cold boot the machine (from the VirtualCenter perspective) to refresh the virtual hardware. Using the Shutdown > Restart option from either VirtualCenter or View Manager (which issues the command via VirtualCenter) is the best way to make sure this file gets read properly.
I quickly ‘Reset’ the Manual Dedicated Windows 7 Desktop using View Administrator and what do you know everything worked!
When creating a manual dedicated desktop, ensure that you reset the desktop using View Administrator otherwise the correct PCoIP settings are not maintained within the .vmx configuration file.
