I don’t have V-Rising, and I’m sure a lot of this stuff is hardware dependent, but according to a couple of reports on ProtonDB, there might be a kernel bug causing issues with it.

I just installed bazzite on my LCD Steam Deck this week and it has been pretty solid so far, but obviously the hardware support for it is top notch thanks to Valve. I didn’t have really any issues with regular SteamOS either and just wanted to try something a bit more customizable.

And really Linux gaming on the Steam Deck feels like cheating, especially compared to trying to run games via wine before the proton days.

You can use Bitwarden to store passkeys. Not sure if the self hosted solution has support for it yet though.
