It does I play quite a bit of VR on Linux. The only think that does not work is the valve index audio output so I use Bluetooth earbuds

Valve has done a pretty good job. Probably because of their ownership model

Most of the time it is to avoid xyproblem.info

Sorry I can’t help with the proxmox stuff but it is absolutely fine to have a qcow2 image on an SSD pool. Modern SSD write endurance is so high as to be a non issue especially in the relatively tiny work loads that HA will put on it

This is huge for me as well and is what will keep me on Ubuntu Server until I have a very very good reason to leave or someone else adds it.

Sounds good to go then. I would appreciate it if you let me know how it turns out

depending on your needs you can setup two uart components wand wire them up. I would think that the best way to do this would be with a custom_component here is a good starting place. I’m not sure id the esp32 has the right hardware on board as one of the uarts is send only and it does not support software uart. This sounds like a really interesting problem. Please let me know how it goes or if i can be of help
