Hardware-accelerated GPU scheduling causing BSOD

Hi, I seem to be getting BSOD when using Hardware-accelerated GPU scheduling = ON.

My configuration is:

• OS: Windows 10 2004 (build 19041.388)
• Motherboard: Asrock z77 extreme4 motherboard with Intel HD graphics 4000
• GPU: Gigabyte GeForce GTX 1080

Windows features enabled:

• Virtual machine platform
• windows hypervisor platform
• windows sandbox
• windows subsystem for linux

I have one monitor (monitor1) connected to the GTX 1080 card, and the other (monitor2) to my integrated graphics on my motherboard. I have WSL2 and Docker running fine on my PC, so interoperability with Hyper-V is working well.

I have noticed that when I set Hardware-accelerated GPU scheduling = ON, my PC has a BDOD whenever I place specific applications (like Remote Desktop Connection) within monitor2 which is using Intel HD graphics 4000. I also noticed I get a lot of HAXM errors in my event viewer e.g. HAXM can't work on system without VT support . I'm guessing my problems are a result of HAXM not being compatible with Hyper-V, so that when Hardware-accelerated GPU scheduling = ON, it is trying to use HAXM for GPU acceleration on monitor2 (using Intel HD graphics 4000), which then results in a BSOD? The BSOD error reports a problem with dxgmms1.sys.

I have ordered some DisplayPort cables so that both monitors will run from the GPU, and will disable integrated graphics to avoid problems like this in the future.

Thanks for any insight.

Ooook your problem is not related to Hardware-accelerated GPU scheduling nor to virtualization , this is all related to you having both Nvidia and Intel GPUs enabled on same desktop .

You have to disable the Intel GPU by mother board Bios settings once you install a high performance GPU else on using it you will get a BSOD .

Basically dual graphics is aimed only at laptops , and shouldn't work on desktops .

If dual graphics setting worked for you any time earlier that is an abomination that should be studied .

Well I have always been able to use one or more monitors connected to the GPU card and the other connected to my motherboard integrated intel GPU no problems. For years in fact on different computers. I don't see how this alone would cause a BSOD.

You were blessed but now you are not ?

Now like I said :

If dual graphics setting worked for you any time earlier that is an abomination that should be studied .

For example this is a snapshot from Nvidia's control panel for laptops :

Notice on top you get to select which GPU to use .

Now this is Nvidia's control panel for desktops :

Notice they do not even integrate the ability to use dual GPUs and they even instruct you to disable integrated graphics pre-installation of new card for not to cause any conflicts .

Think about it , if you run a game , how would a desktop choose which GPU and monitor to use for that game in absence of such a preference in the Nvidia controller ? Hence why I told you if it ever worked for you is an abomination .

Now if you are ready to trouble shoot how was this possible for you in first place you need to answer the following questions :

1 - Do you currently have a "Preferred Graphics Processor " option in Nvidia's control panel ?
2 - If not , do you recollect ever having it ?
3 - If not how did gaming behave once running , which monitor they played on ? the one plugged to the Nvidia's or the Intel's ?
4 - Have you updated your Nvidia's , Intel's drivers lately ?
5 - Have you updated your Bios ?
6 - Have you upgraded your Nvidia GPU lately where this surfaced with the new one only ?
7 - If yes what was the older GPU , and did you use DDU to uninstall its driver prier to plugging new GPU ?

Thanks for the effort of answering these questions in advance .
