Could it be that unraid disabled monitor output?

I have iGPU and external GPU, while booting monitor shows output. But then it disapears. 


I want to use iGPU for unraid (output to monitor (or in this case tinypilot)) and eGPU for plex docker.

 

Using latest RC.

Nvidia Plugin.

 

Everything else is working. Just want to get an output over VGA

 

edit: im currently on latest stable 6.9 (not RC1 till now)

ive even changed boot to gui boot, still no luck,

 

no monitor output after boot complete (i see unraid starting, i see menu for GUI and so on)

 

Any help?????

 

Bios enabled everything regrading to gpu

 

I want to put a kvm at it so i can control it outside the "server room". But without display....?

The behaviour sounds like a situation where the GPUs have been reserved. In this scenario, the boot sequence shows up to a point, but appears to stall.

 

Have you a clean unraid install, or have you ever set any VFIO reservations for passthrough? (if you have, and the n shifted or added devices, the assignments can change and th wrong devices can become reserved).

Its booting just fine. It just stops outputting to VGA.

 

As far as i know there is nothing reserved just the latest update with nvidia for docker

So do you get as far as a login prompt?

 

What is igpu? Have you tried loading driver for igpu? 

 

My supermicro machine blanks monitor afterwhile and need to press keyboard to wake screen but after a while once at login prompt.

igpu drivers are now included but i also tried to load it via modprobe, doesnt changed anything

 

I did not see login promt, but i saw the things before (after bios, but before login)

 

Its intel onboard

 

isnt there some fancy linux command to check if its atleast tryin to output something?

latest 6.9. RC1

 

crazy kernel panic...? maybe related to vga? im not sure

Mar 10 22:02:05 Unraid-Server kernel: Console: switching to colour dummy device 80x25

Mar 10 22:02:06 Unraid-Server kernel: vfio-pci 0000:00:02.0: vgaarb: changed VGA decodes: olddecodes=none,decodes=io+mem:owns=io+mem

 

besides the kernel panic everything seems to work (?)

One of my machines has iGPU and Nvidia Card.

 

There was an issue getting a blank screen with GUI if ich777 intel_gpu_top was installed, which he has now fixed.

 

I have the done the following:

 

touch /boot/config/modprobe.d/i915.

install intel_gpu_top

 

Server boots into either text or gui console. Before the fix gui was just showing black screen with solid cursor in the top left.

I dont thionk this has anything to do with my problem. Because it just shows "no ouput" not a blank screen.

 

But i did it anyway:

root@Unraid-Server:~# touch /boot/config/modprobe.d/i915.
root@Unraid-Server:~# 
root@Unraid-Server:~# install intel_gpu_top
install: missing destination file operand after 'intel_gpu_top'
Try 'install --help' for more information.
root@Unraid-Server:~# 

 

Do i need to somehow tell unraid to use the iGPU instead of the normal GPU?
