Yesterday, July 1st, they announced the Alpha release of this next-generation mod manager and their new Product Manager got in touch to mention they “would be really keen to get feedback from Linux users”. So this is your chance to ensure Linux (and Steam Deck) finally become a first-class citizen for game modding.
if you have an amd gpu and install bazzite its basically the steamos version valve hasn’t released yet but with a fedora base instead of arch. I wouldn’t actually do the deck image though because game mode is kinda annoying unless controller really is your primary input. I use the desktop image on all my computers that aren’t server use.
