Hello Community,
I am currently facing an issue with my Debian 10 Hyper-V virtual machine when attempting to passthrough an NVIDIA GPU from the Windows host. I have set up the VM, mounted the NVIDIA GPU using DDA (Discrete Device Assignment), and installed the XFCE desktop environment. However, upon boot, the screen goes blank, and the desktop environment fails to launch.
Debian VM Host System GRUB menu.
Debian VM Host System Blank Screen Issue.
Here's a brief summary of the issue:
- Host System: Windows with Hyper-V
- VM Guest System: Debian 10
- Debian Desktop Environment: XFCE
- GPU Passthrough: NVIDIA GPU using DDA
Issue Description:
After mounting the NVIDIA GPU to the Debian VM, the desktop environment fails to launch, and the screen remains blank.
However, I can switch to TTY mode (terminal) using Ctrl + Alt + F1, where I can verify that services like Light Display Manager are running correctly.
Additional Information:
Debian 10 VM works normally without GPU passthrough.
I dismounted the GPUs from the Debian VM and rebooted the system; it boots normally in the XFCE desktop environment.
Please check the following screenshot.
If anyone has encountered a similar problem or has expertise in Hyper-V GPU passthrough with Debian, I would greatly appreciate any insights or guidance on resolving this issue.
Thank you in advance for your help.
Best regards,
Samadhan
