No video from onboard Intel GPU GUI Mode

[jhmars]

UnRAID version 6.9.2

This is a new install on new hardware, with a new user...

MB: Asus Prime H570-Plus

CPU: Intel i5 10600K

GPU: installed but not set as video source, intended for passthrough to VM.  This has been bound to VFIO at Boot through the system devices tool.

Problem now presents as a loss of video output at the point the local GUI should start.  I see the boot menu, select Gui Mode, loading scripts/text, then no signal to monitor.  The server is running and accessible from another computer but it was intended to be used locally and this solution is not sustainable.

Fixes I have tried include;

booting Legacy - no boot menu or server at all

Install Intel GPU Top plugin

confirm CPU graphics are selected in bios

adding a 'i915.conf' file to /boot/config/modprobe.d/  as defined in the 6.9.0 Release notes for GPU driver integration.

And several combinations...

 

Full logs are included as it looks like there are erros related to the i915 graphics during boot.

 

The below is a selection from one of 2 or 3 similar errors.  Any help the community can provide would be greatly appreciated.

If you bind the GPU to vfio then this will hide the GPU from Unraid and stop UnRaid from being able to use it for GUI mode display.   If you start the VM does the VM see it?   If so then setting the VM to auto start might be the best way forward?

I'm experiencing the exact same issue, I just installed the Nvidia plugin to see if that works and it has allowed me to boot into Unraid GUI, but I want to use my Nvidia card for passthrough to VM. I'm wondering though, do we need HDMI connected from monitor to the motherboard for Intel GPU Top, or can it remain plugged in the main GPU?

Its one or the other, you cant use the nvidia card to use in gui and a VM at the same time

Yes, I'm aware of that (I will be uninstalling Nvidia Plugin shortly). I was unable to boot into GUI after installing Intel GPU Top though, and I'm just wondering perhaps I need to plug my video cable into that to load up Unraid GUI, and then plug in a separate video cable directly to Nvidia GPU once I've booted into a VM?

Ah yes, sorry i get you now.  Yep, one cable for each device(onbard/GPU card), then just swap your monitor input to whichever one you want

I haven't gotten far enough to set up the vm yet.  I'm considering just proceeding as you say, (auto start vm) but was hoping to find a resolution to the on board graphics issue.
