[Unraid VM USB Issues]

I posted a while back about my inability to get a GPU output from my VM. I fixed that.

 

About an hour later, i attempted to install my Rift S headset, it showed up in Unraid as a USB device, and also in Windows.

 

After installing the Oculus software, the device then refused to show up in unraid after the next reboot.

 

I've tried different ports, a seperate USB PCIe card, and rebooting the server multiple times with and without the HMD. 

 

What would any of you recommend as the next step?

Did you try the HDMI dummy plug as was suggested by the previous poster?  If you want to run headless, you need this.

I went a similar route, plugging the onboard graphics into the Big TV (the one in the living room), and the Small TV into the RX580 (we knew this worked already) and everything seemed fine.

 

Unraid was able to output it's startup log to the Big TV, and the VM started up perfectly fine on the Small TV.

 

The problem is that I can't have it the other way round, Windows being output to the Big TV (Solid black screen, but not saying "No Input Detected") and Unraid being displayed on the Small TV (still outputs the log and the IP address on startup as normal.

 

I think it's something to do with how the Big TV interprets the signal, not a hardware fault.

 

If it comes down to it, ill order a headless adaptor and see from there, but it doesn't seem like it'll solve anything.

Hi, I had this in a different forum section, but i didn't get any further assistance, apart from 1 person.

 

I've set up an Intel Unraid System (6700k, Z170 board, 16GB RAM, RX580 GPU).

 

The problem i'm having is the Windows 10 VM will only be able to output video to a specific output display. (Backup TV works, main TV doesn't).

 

I wanted to set it up as a VR rig in my living room, and before this, it had Windows 10 directly installed on the SSD's and worked with out main television.

 

After instaling unraid, setting the Intel Onboard GPU for unraid and the RX580 to the VM, it refuses to give any display out, unless i plug it into a spare tv in another room, which enables the display output and shows up.

 

Is there something in Unraid to tell it to output a signal regardless of what it's plugged into, or would this be a TV issue (keep in mind, it worked perfectly before, with the same GPU, Same TV, Same cable, Same port).

A few things to try:

• Try various combinations of SeaBIOS / OVMF and i440fx / Q35 machine types. Switching between SeaBIOS and OVMF may require reinstalling Windows, depending on how it was installed. Switching between i440fx and Q35 will just be slow on initial boot as drivers get reinstalled. Either kind of switching may require you to reactivate Windows so be mindful of that.
• Try a dummy HDMI plug (can be found for cheap on Amazon). It tricks the GPU into thinking a display is connected and initiates itself. Reason the RX580 works with baremetal boot was because it's the primary GPU and thus is always initiated at boot.

Hi,

 

After trying an assortment of different BIOS and Machine Types, nothing seems to work if I boot it with the GPU as the Display Output.

 

I know the VM is able to output video through the GPU as it works on another monitor without issue.

 

Would that be an issue with the TV not detecting the input, or is there something i can change in Unraid or the VM to force it to output to that specific TV?
