I’m new to lemmy and linux, been daily driving Ubuntu 23 for 2 months and had nothing wrong happen, when I went distro hopping, witch I won’t ever do again, everytime I tried to mount a steam apps folder it wouldn’t show my apps, idk if this is a bug but I’ve gotten it fixed by creating a steam folder then copying all my games and placing them into the new folder, but if I clock on the repair folder it would create a new one and completely brake it. Anyway u just wanted to share my findings, I hope this brings more light to someone who has this exact issue :)
Did you add the folder as a steam library? Mounting it does not make steam detect it. This is true on all OSs steam supports.
