January 30, 20242 yr Hi all, I've tried looking around for this online but haven't cracked why this is happening yet. I have my old RTX 2080 in my server machine, it's bound to an IOMMU group (no Nvidia driver installed in Unraid). I can confirm it can be picked up in Linux VM but only as a secondary GPU, the Linux drivers work and I can confirm Nvidia X Server sees the GPU and can control it with no issue. if I switch the 2080 to primary GPU the machine(s) shows no sign of posting. No error(s). I've installed both AnyDesk and Parsec to detect and access the VM after posting, both are set to autostart with the VM and I have confirmed they both start without any input from the user after booting. I can only assume the machine(s) aren't posting since neither apps can see the VM(s) anymore. So I've only tried 2 distros, Pop! OS and Manjaro, but it's strange it happened the same exact way for both. I'm sure there's a more elegant way to test this and see what the issue is, but this was my (admittedly) beginner level troubleshooting so far.
