Regarding wonky links, I can’t say I’m familiar with the issue. You could try checking Mint’s desktop files to see how the commands are set up, and if they work fine manually through the terminal. If they don’t, that’s probably an indication of where the issue is.

Regarding videos, those are… problematic, some times even on Windows (FF Type-0 and Mary Skelter PTSD intensifies). Perhaps you’re missing a drive, or Proton’s equivalent of winecfg may need some manual tinkering.

And regarding auto-mounting drives, are they being automatically mounted to a static path, and before Steam is loaded? Also maybe deactivating Steam’s auto-start, if it’s active, helps?

Afaik, Termux is an actual Linux system made for Android’s file system and that runs inside an app, so it actually can do a whole lot more, provided there’s a tool ported for what you want. It can even run some graphical distros.

I don’t know how much of a subset I am, but I still use dictionary softwares from Windows 95~2000 era and Android softwares on a completely offline and vanilla VM, partly due to internet randomly going bad, and partly because I am neurotic about digital contents vanishing once support ends.

Can it be used offline?
