Proxmox with AMD GPU passthrough black screen

[mkuznetsov]

Latest release. Installed successful on ProxMox VM with AMD iGPU 780M or 610M. But after installation first launch is black screen. Tried hdmi cable plug in, nothing is outputted via hdmi (in some os don't activated gpu without monitor).

Can I get some ssh access to check logs or install sunshine for streaming? How cat I check installation without gui? Are there any rescue mode with console output?

SteamOs installed with same hardware, but I need heroic with another stores. Holo Os don't try yet.

I was able to login into desktop, console TTY. I opened Steam as an app and login. GUI was ok and fast. But than I switched chimera-session to steam or steam-plus or opengamepadui I get a black screen.
I tried clean install on external drive and boot from it. Same black screen.

Is it an unstable version? It might be due to mesa 24.0.2.

[mkuznetsov]

it is 2024.02.04 stable version, that currently on site. I download it from site. I usually don't use night builds for first installation of product.
It looks like steam have some init problems, because desktop have no issue to render with same igpu passthrough. I played on same igpu in windows with steam, but I want higher fps and better gamepad support.

Any updates from team?

We explicitly don't support virtualization in this way. The kernel we use disables some stuff for this as well. I think the better way would be for a plain arch install here.

It is sad, It will be a great options especially if it will be provided with sunshine streaming. Than it will be ultimate homelab gaming rig what will work with any moonlight client and it’s gamepad support.
