Jack_T Posted December 9, 2020 Share Posted December 9, 2020 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 Quote Link to comment
flexage Posted December 12, 2020 Share Posted December 12, 2020 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: Quote Link to comment
Jack_T Posted December 14, 2020 Author Share Posted December 14, 2020 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! Quote Link to comment
