When connecting to a new desktop from the Horizon View client or a PCoIP Thin/ZeroClient, one or more monitors shows nothing but a black screen.

To resolve this, simply power down the desktop or desktops. As long as the View pool is set to always keep desktops powered on then View will power back up the desktops after the reconfiguration has finished.

To automate this process a layer script can be set to automatically power down the desktop before the desktop creation task completes. This can be set on an app layer or the OS layer. To do this, add a version to the layer that you want to copy the script to. The new layer wizard will have a "Layer Script" field. Place the full path to the script there. For example "C:\Windows\Setup\Scripts\AutoShutdown.cmd" minus the quotes. This script will be run once and then deleted.

See the AutoShutdown.cmd script attached.

Problem Cause

When Unidesk creates a new desktop, it will only set one monitor and use the video RAM setting set from the gold image when it was imported into Unidesk. This is typically not enough as many deployments use two monitors or more and even with one monitor they may need more video RAM than was initially set in the gold image. All of these settings are changed by Horizon View per the pool settings. When a desktop completely powers down, View will check on its configuration. If it finds the desktops settings are out of spec per the pool settings then it will reconfigure the desktop to match those settings. Unidesk will reboot a new desktop multiple times during setup but it is never powered down which triggers this change.
