do you use Moonlight, Sunshine, SteamLink or something along those lines?
My linux server is wired to the router, but I use SteamLink hardware with 5GHz wifi. I haven’t tried Moonlight & Sunshine, but I have tried a myriad of different hardware running the SteamLink app, but the SteamLink Hardware > RPI 4 > RPI 3 > CCwGTV. For me, the SteamLink hardware has always been reliable enough that I didn’t need to explore other options, but YMMV.
I would strongly recommend that you disable Wayland and continue to use X for various reasons, but the three most important reasons:
- Nvidia and X allow you to inject a custom EDID so an HDMI dongle isn’t necessary `Xconfig: (Option “CustomEDID” “GPU-0.DFP-3:/path/to/edid/file”)
- Wayland doesn’t support disabling V-Sync (it may now), but if not, you really do not want V-Sync enabled when streaming
- XWayland is gonna drop your performance 1-10% depending on the game and situation…
If you end up switching to AMD GPU in the future, you still don’t have to have an HDMI dongle, but the AMD process of injecting an EDID is much less user friendly to the point where you will want an HDMI dongle. :-)
I connect to my server via SSH and if I need to see the screen, RealVNC on my phone… no monitor, keyboard, or mouse connected except when I might want to update the BIOS or something.
Good luck; let me know if you have any other questions :-)
