Hi there!

 

Hoping someone has come across this exact issue but I have recently just built a new Unraid server with a 5950X in it and for whatever reason I am getting no signal on the monitor after unraid bootstraps. I’ve tried Unraid without the GUI, with the GUI, safe modes, nothing seems to get past the initial init. I see the kernel load up, devices are attached but after the wall of text, nothing happens. 
 

This is a UEFI boot and I’ve made sure that the EFI folder on the boot drive is “EFI”. I’ve disabled Secure Boot also. 
 

I’ve tried seeing if I could somehow get to the terminal but I can’t. Or maybe I can but the monitors signal is gone. 
 

I have an old R9 290 as my graphics card, along with a 5950X. 
I can get TrueNAS to boot fine, just Unraid after the init just doesn’t work. 
 

I have tried looking around the forums for advice, I did come across potentially allow listing the CPU but I wouldn’t know what to modprobe with.

 

Any help would be hugely appreciated because I want to get started!  

I remember that once I had such an R9 beast too... It did not work well, with many OS.

If, by chance, you have a different card as an option, give it a try.

 

I recently even bought VERY old ATI Mach-64 cards (but PCIe 1x already) from china for less than 5$.

They are simple VGA cards, but thats enough to run UNRAID.

 

Hey! Thanks for the reply. I understand. I don’t have another card to eliminate unfortunately. I managed to boot other OS’ with this card however, so it does work. 

I mean, it does display on, I assume, the basic graphics driver. Does Unraid try to load a different driver after it init’s? I do see things being printed while Unraid loads up, the BIOS comes up, Unraids boot menu comes up. 🤔

if i remember correctly (looong time ago), the problem was the monitor timings. For graphics mode the card reclaims strange settings that many monitors deny.

Try to boot non-gui unraid or even non-gui-safe mode.

 

The UNRAID GUI trys to fire up an XServer and a Desktop. This may be the problem.

 

I’ve tried all available options for Unraid, including CLI Unraid in safe mode. 

 

For whatever reason, it just won’t go past the init. 

I’ve included a photo of the final steps of the init before everything goes dark. 
 

I’ve since enabled Virtualization in the BIOS, same issue. 

 

I have the strong faith that it DOES continue to boot and run. You just dont see anything.

Have you tried to access UNRAID from a different machine over the LAN?

 

Also... sounds stupid, but give it a try:

* turn off (or unplug) the monitor

* boot the PC with unraid

* wait until it has settled (HD activity or something)

* turn on the monitor.

* pray :-)))

 

There’s no IP assignment even though I selected DHCP from the Unraid USB Creator.

 

I tried your suggestion but no dice unfortunately. 

 

Personally, I think the reason is it’s using Radeon mode setting and that’s causing some issue. I’m trying various kernel parameters to see if something sticks. Could be wrong though, not the first time. 😆

you did not pray long/well enough :-)))

 

 I dunno which Mobo you have, but many are able to run without any graphics card (console to serial port). If this works, pull out the radeon completly and see if it finishes booting and starts lan.

Else my last idea would be my first idea again: get a different graphics card...

 

Try blacklist the Radeon driver from loading, see how to here:
