I experienced myself an issue with an AMD Radeon WX4100 GPU having a black screen or desktop “freezes” at login and by adding CitrixIDD registry key I got it working. Other GPUs may be impacted so please test. Please be aware that with implementing Citrix IDD you loose vendor specific (control panel) settings, because Citrix bypass the GPU vendor capture APIs and you will have less performance resulting in less FPS. But I have experience myself that performance works amazing with enabling CitrixIDD and it solved my issue with a black screen/desktop that froze.
Update 29 August 2018
Its recommended getting a native driver from the GPU vendor instead of using Citrix IDD to get the best performance the GPU vendors provide via their APi.
Below is relevant for Citrix customers
Connecting with HDX to machines provisioned manually or MCS or PVS to a virtual Microsoft Windows 10 with Citrix Client OS VDA 7.16 and above.
Connecting with HDX using Citrix RemotePC to a physically PC with Microsoft Windows 10 and Citrix Client OS VDA 7.16 and above.
HPE have released new server cartridges m510 and m710x for HPE Moonshot and Edgeline. These new server cartridges are the first units that have built-in HPE iLO, so customers can easy manage each server cartridge.
Moonshot cartridge building blocks for Citrix workloads
Below chart describes what HPE Moonshot/Edgeline current strategy is for GPU enabled apps and desktops with Citrix XenDesktop and XenApp.
HPE Moonshot have been around for some time now, and I have been very lucky working together with HPE and testing their server cartridges that are compatible with Citrix solutions. Last year, at HPE Discover in London, I wrote an article about how Citrix internally are using HPE moonshot and which server cartridges were available at that time and how financial customers are benefiting from these solutions.
Earlier this year I have seen several customers having issues with AutoCAD in Citrix not defaulting to the primary display adapter, so the GPU wouldn be fully functioning and Autodesk AutoCAD 2016/2017 would turn off hardware acceleration. This issue have been seen on NVIDIA Gpus such as GRID, NVIDIA also have a official KB on this http://nvidia.custhelp.com/app/answers/detail/a_id/4092/ and issue is also seen with INTEL gpu such as Iris Pro Graphics more specific on solutions with HPE Moonshot 710p and 710x.
Issue is identified on both Citrix XenApp 7.x (Windows Server OSs) and Citrix XenDesktop 7.x (Workstation OSs)
“The primary display adapter is not shown as the default in a Citrix environment.”
I am happy to share that Autodesk have finally fixed this “bug” with Citrix and now the GPUs will work correctly with Autodesk AutoCAD 2016 and Autodesk AutoCAD 2017 when you apply below hot fix for the product you have.
