    ESXi 6.5 and Horizon 6/7 Direct Connection = Black Screen on Win7 (32bit)

    KWKirchner Novice

      I had a perfectly working lab setup as of a few days ago where my Win7 (32b) VM was loaded with the Horizon View 6 agent and the direct connect agent. My Terra2 PCoIP client would automatically connect on power-up and life was good.

       

      Yesterday I upgraded my ESXi hosts to 6.5 and my VCSA to 6.5.  Now when my PCoIP clients connect (Terra2 or software) I get a black screen and a mouse pointer.  I can tell that the system is logging in because I still get sound, and occasionally I see a busy pointer as things load in the background.  If I am watching on the VM console, as soon as the connection is made it also goes black. When I disconnect I see the screen come back to life on the console and briefly see the log off message before it goes back to the "Press CTRL + ALT +DEL to log on" screen.  There is NO DISCONNECT after 10 seconds as is mentioned in many KB articles, it stays connected like nothing is wrong.

       

      I have tried installing the latest VM Tools (even omitted SVGA driver), upgrading to Horizon 7 agent/direct connect, upgraded the VM hardware to v13, and none of that seems to fix this problem.

       

      Does anyone know what might be causing this?  I do not have any of the Connection Server/Composer nonsense to deal with and like I said, as of a few days ago this all worked perfectly. I can't see the VCSA update as having anything to do with it, so it must be an issue with ESXi, but what? What would knock out the video, but not the mouse or audio? It has to be something with the SVGA driver. There is 32MB of mem and 256MB for 3D on a 1900x1200 screen. It was set to auto and had 17.3MB assigned when it was working. I increased it to see if it would fix the issue, but no luck.

       

      Tomorrow I will rebuild a host with ESXi 6.0 and migrate the VDI desktop to it and see if it comes back to life.
