I have a Motherboard without video port (Asus P6T ATX LGA1366)

and I successfully made a "GPU passthrough" with a Radeon HD 4890

for a Windows10 VM.

 

When the VM start the screen pass from Unraid text mode to the VM Windows screen.

 

But when I stop VM once, the screen remain black, and I can't use it neither for Unraid nor for the VM.

 

How can I get back normal use for the GPU/monitor?

Is it possible?

 

Thanks

It sounds like you're suffering from the AMD GPU reset bug, it's a known issue.

 

I've heard reports that the `very` latest AMD cards have fixed this bug, but can't confirm.

 

I'm surprised that you haven't had any replies to this topic after so long.

 

A sure fire way to get your AMD GPU back up and available is to reboot your Unraid box.

 

If you don't want to have to reset, SpaceInvaderOne has a method by which you make a script that removes the GPU from the system, then puts it into standby, then re-initialises the GPU when you wake the system back up.

 

I tried it but didn't have great success, and I felt dirty afterwards 😂

 

Here's a link to SIO's video about the process: 

 

I already try this script but notting happened...

the difference between me and the video, is that I have only one single GPU.

 

And when VM stop, the problem is not relaunch the VM, but I want to give GPU back to Unraid interface...

 

thanks!
