Having grey screen issues with CVAD 2203+ and higher on Windows Server 2022 Terminal server? I had this issue occurring on Citrix 2212. Try running this script. It might help you out. Do a VM backup or snapshot before running the script, just to be sure.
$iddHwId = “VEN_5853&DEV_1003”
$pnpDispDevPath = “HKLM:\SYSTEM\CurrentControlSet\Enum\SWD\RemoteDisplayEnum”
try
{
$iddDevEntries = Get-ChildItem -Path $pnpDispDevPath -ErrorAction Stop| Where-Object Name -Match $iddHwId
}
catch
{
Write-Output “Failed to query remote ID device entries”
Write-Output $_
return
}
if ($iddDevEntries.Count -eq 0)
{
Write-Output “No remote ID device entries found.”
return
}
$iddDevEntries | ForEach-Object {
$devName = ($_.Name -Split “\\”)[-1]
try
{
Remove-ItemProperty -Path $_.PsPath * -ErrorAction Stop
Write-Output “Cleared values for $devName”
}
catch
{
Write-Output “Failed to clear values for $devName”
Write-Output $_
}
}
This saved my day:
