I found a reddit post from a year or so ago, reportedly Bazzite has drivers for the dongle out of the box. I’m a little more concerned about the keyboard+touchpad combo, since I’d imagine that’s not quite a standard device. Fortunately, I give negative fucks about any RGB, so I really don’t care if any RGB the components happen to have don’t even light up.
The basics (getting the OS installed, some initial settings to your liking etc) is quick. Managed to go from “completely untouched build” to “we gaming on Linux now boys” in a couple hours and most of that was waiting for BG3 to download on my 100Mbit connection. Pretty much everything I needed worked right on the first boot. Then again, I didn’t have much data to transfer over.
