Huh. Mmmaybe the LCD model has board revisions that are still different enough to trip things up? It's definitely a bug to have wireplumber not "do the right thing no matter what hardware it booted up on today", it would probably take a Valve engineer to chase that down and submit a patch.

👆 this sounds like the most probable fix. I suspect OP buried a very critical factoid - moving the drive between OLED and LCD models. The systems have some significant hardware differences (as evidenced by the Windows drivers changing so much that Valve took a long time to update em). Somewhere, Pipewire has squirreled away details about routing or preferred devices from the old system.

Heck, there might be journalctl log entries being generated you plug into the headphone jack. Pipewire could already be trying to tell you exactly what's wrong.

Fields of Mistria.

Just finished up "Last Time I Saw You", ehh I think it's the weak one in the "Until Then & Space For The Unbound" untrilogy.

The HDMI port on any dock is output only. You would have to get an HDMI capture adapter to go that route, and watching those live with low lag is problematic. Beware of capture adapters that are USB 2.0 (a lot of cheapos will lie about this).

Another way to go would be Steam Link over wired ethernet.

One last way, which involves only one higher-end USB-C cable, would be to directly plug the deck to the tablet. One (or both) would act in a CDC-ether role to network the two together. (How do you simultaneously access the internet/Steam's servers?). This setup is very fussy on the software side. I have been remarkably unsuccessful at connecting the deck to a laptop in this fashion, but Android is more open to doing "dual role" usb stuff.

Steam should be loading a separate controller config for every game, or at very least loading a default profile of "every button is literally the same as on an Xbox controller". A weird SteamInput config shouldn't affect across all games, I think.

Does it act up in Desktop mode? How about if Steam is closed, and you play something from Heroic?

It's possible that a hardware fault is sending insane inputs. Bad connections to the controller-sub-boards? The controller microchip just going batty?

It's doing the right thing - most of the harm has been done with the battery being charged up in the first place. If you can pull power from the wall instead of battery, do it. Ordinary usage will chip the battery down to the charge limit in due time.

I have an ASUS laptop which does not do this. When you turn on the battery limit, it stops pulling power from the wall until the battery is down to the right place. Very rude.

It sounds like they have to wait for support to move from the Steam Client Beta to mainline. That happens on Valve Time, so they genuinely do not know.

SteamOS isn't really meant for any system outside the Steam Deck and a handful of similar handhelds. I'm pretty sure it doesn't have any Nvidia drivers, for starters.

Bazzite and Nobara are the general answers to gaming on any random PC hardware.

Finally!

Terminal/Esc looks interesting

Opening something that's a (mostly) static page works. Doing anything that involves talking to a database, such as aggregating your wishlist or searching for a game, is hopeless.

Try searching for any game, any game at all. Steam can't do it.
