[R9 380x passthrough black screen]

An update to those who might need it.
I got it working by applying the reset around by disabling the gpu and it’s sound from device manager before reset and shutdowns.
Doing this using devcon.exe
See here

My only issue is that I can’t automate it as described because the script has to run as administrator, otherwise it’s not working.

Thank you for your response
I can’t even boot the win installer with OVMF.
I’m now q35 and SeaBIOS and win 10 build 1903.
Will stubbing the gpu help? Or do the safe ejection of gpu before shutdown can help?

Ok so I reinstalled the vm and win10 recognized the GPU and installed drivers.
Now I’m getting the 127 header error upon restarting the vm...

Hi guys and girls!

 

I had my setup running with FX-8300, m5a97 R2.0 and HD7770 for some time and I was enjoying it.

I got a r9 380x and I can't get it to install drivers.

the new one get me a black screen after reboot.

the older once (17... and 16... versions) not detecting the GPU.

without drivers its working with the basic adapter of win 10.

 

The vm is set with SeaBIOS and i440..

 

any idea?

thanks a lot
