Wired Connection: Infinite loop of "Server connected" and "Server disconnected"

[rijenkii]

OS: Fedora 43
Steam is running as a native RPM, no flatpaks.
ALVR v20.14.1
No firewalls are running, firewalld service is disabled.

Enabling "Wired Connection" begins a two-minute loop of connecting/disconnecting to the server.

Any way to debug this? Current suspect is a low quality of the USB cable.

[Stavdel]

Has this ever worked before?

Your logs show you're on AMD integrated graphics, that's why encoders aren't showing up and why you're getting the performance warning.

Do you have a dedicated GPU? Run lspci | grep VGA

If you have a discrete GPU: You need to force ALVR/Steam to use it instead of the iGPU.

If you only have integrated: I haven't tested this, but try installing VA-API drivers with sudo dnf install libva-mesa-driver mesa-va-drivers to expose encoding. Fair warning though, VR on iGPU is gonna struggle hard, hence all those warnings in your logs.

[rijenkii]

This is the first time I am trying out ALVR, so this has not worked yet.

I have no dedicated GPU, but I was not planning on gaming yet -- I know that iGPU will struggle with that. I was just wanting to try ALVR out with poor FPS before buying a GPU, and I do not see the correlation with poor performance / lack of encoders with the observed behaviour.

libva-mesa-driver is not a fedora package, installed mesa-va-drivers and will report results later.

[rijenkii]

Did not fix the problem, logs are pretty much the same except now there are less complaints about the GPU/encoders:
