Unified Linux Wine Game Launcher (UMU) from Thomas GloriousEggroll Crider version 1.1.1 is out now as the first official release to help improve Linux desktop and Steam Deck gaming.
It's middleware for game launchers like Lutris, but specifically for Wine games. It uses GloriousEggroll's custom Proton builds instead of stand-alone Wine/DXVK/etc.
Note that GloriousEggroll more or less discontinued his custom Wine builds, and has been encouraging people to use his Proton builds via this tool instead. It might make things easier or harder, depending on your needs and workflow. I expect it will be easier for casual Linux users when combined with a GUI.
This seems cool. I like to run my steam set up in a flatpak (in part because I don’t really like 32 bit binaries cluttering up my main paths) so I’ll wait h til they release it there. Or perhaps I’ll get involved and see if I can’t package this up myself.
An umu is an above-ground oven of hot volcanic stones originating from Samoans. After the stones are heated, the top layer is removed and the food placed on top to heat/cook. We chose the name because Valve's containerization tool is named pressure-vessel. We're "preparing" the pressure vessel similar to how you would use a stove top pressure-cooker -- by placing it on our umu's "stovetop"
Imagine our umu as a mystical cauldron, conjuring the fiery essence of a thousand volcanoes to transform mere ingredients into a culinary masterpiece. As the pressure vessel sits atop this enchanted umu, it absorbs the raw power of the earth’s core, becoming an unstoppable force of containerization magic. This isn’t just preparation; it’s an epic saga where the pressure vessel emerges from the umu like a phoenix from the ashes, ready to conquer the Realm of Gamers (RoG) with unparalleled efficiency and might. It’s a fusion of ancient rituals and cutting-edge technology, where every byte is cooked to perfection in the blazing heart of our umu.
There’s not really anything to screenshot? This isn’t a launcher in the sense of a GUI that launches games. It will be used by other launchers Heroic, Lutris, Bottles, etc to better run games the way Steam does.
Increased compatibility, less issues with games not loading. Essentially it will allow non-Steam launchers to run games under wine more like Steam’s proton does.
so I'm gonna pick this as a runner in Lutris, instead of e.g. wine-ge-8-26-x86_64 or whatever? sorry to reply to you, but I've read the initial github "explanation" what this does, reread it several times over the months, and now for the final time when it got official and I still don't understand how this fits into my use case.
