Any way to reset Lutris + Wine to "factory settings"?
I’m new to this and have been trying to get Fallout NV to run on my Chromebook Plus. I had Fallout 3 running great but at some point I did something so that FO3 fails to launch.
Can I do something like a fresh install? I don’t care about losing data/ games.
WINE lets you create isolated (well, semi-isolated...it's not a sandbox, but separate Windows registries and most drive letters and such) directories. That directory is called a "WINE prefix". Contains symlinks to Windows drive letter locations, a copy of that WINE environment's registries, the WINE settings being used. I believe that the "Z:" drive defaults to being shared and mapping to "/" on your Linux box.
I believe that the default WINE prefix is ~/.wine.
But you can create others. Like, maybe you want a 32-bit and a 64-bit Windows environment.
You can run a given executable in a given WINE environment by just setting the WINEPREFIX environment variable, like:
$ WINEPREFIX=$HOME/.mywineprefix wine Foobar.exe
It's become somewhat common to create a separate WINE prefix for each application, especially games, which don't need to interact with each other. That way, installing software in one prefix or whatever doesn't dick up the others.
I don't use Lutris, but if it works anything like PlayOnLinux, it might create a per-game WINE prefix. I don't know where it's located, though. Can probably search online.
Steam creates a per-game WINE prefix for Steam games that use Proton, their version of WINE; it uses ~/.steam/steam/steamapps/compatdata/<steam-application-id> for each.
Careful deleting the prefix, as it will delete game save data. I'd suggest backing up the data, and the prefix, before creating a new one. Just rename the prefix by adding --old to the end and move the save game out of the prefix
It creates an arborescence that contains the necessary library for you application to work with a thick layer of magic on top of that to make it all work. This is were my understanding is at at least
There's another comment that explains it in more details than me but it's a hierarchy of files your C://user/you/appdata...etc and since it branches into multiple choices you can call it an arborescence if you will.
