Windows 10 / Nvidia Grid No Full Screen session

[Xavier Blackwood]

Hi,

 

Citrix support isn't very helpful anymore so I'm asking the forums.

 

We have used NVIDIA Grid gpus with Server 2016 & 2022 with success but now need to spin up Windows 10 VDIs for specific users. The issue is when using the Grid GPU cards, the sessions cannot go full screen and have a grey border around it. What am I missing here, hopefully something simple and not a bug. The sessions can go full screen without the GPU profile assigned.

 

VDA 2203 LTSR CU1.

Windows 10 22H2

XenServer 8.2

I have usually seen this if the wrong license is applied to the vgpu.

Interesting.. I'm pretty sure we only have the one type of Nvidia licenses (Apps). I can see the Windows 10 VDA pulling the license correctly too. Is there a different nvidia license for Windows 10 VDAs vs Server 2022 VDAs..

Hi Xaviar

 

are you using graphics profiles or GPU passthrough?

 

I'm guessing your using GPU passthrough. Try setting a profile and ensure that a vApps license is applied. This can be controlled via registry keys.

Are you publishing apps on the Win10 VM or doing full desktop? We are doing Virtual Apps on Win10 for a "special" app and we are running into this too.   If this is indeed a license issue wondering if its seeing this as a Virtual Desktop and not Virtual App.    We too only have vApp licenses.

Guys

 

Are you using a vGPU profile or passing through the whole GPU?

Profiles.   We have NVIDIA GRID vGPU grid_p40-1a currently assigned.   App resolution is being set to 1280x1024 according to monitor / director.

On the Windows 10 VDI, check the following registry key

 

Key:   HKEY_LOCAL_MACHINE\SOFTWARE\NVIDIA Corporation\Global\GridLicensing

Data: FeatureType

Value: 0

 

if not zero, set it to zero

 

Also, have you copied the client configuration token file created during the DLS installation/configuration, (to the gold image if provisioned) VDI in folder 

C:\Program files\NVIDIA Corporation\vGPU Licensing\ClientConfigToken?

You need to reboot the VDI after this for the license to work

 

after the reboot, RDP onto the VDI and type the following

 

cd \Program Files\NVIDIA Corporation\NVSMI

nvidia-smi -q | findstr Licens
