# Proton
|
|
|
|
[Proton](https://github.com/ValveSoftware/Proton) is a compatibility tool for
|
|
[Steam](./steam.md) by its developers, [Valve](https://www.valvesoftware.com),
|
|
based on [WINE](../linux/wine.md).
|
|
|
|
## GE-Version
|
|
|
|
[Proton GE](https://github.com/GloriousEggroll/proton-ge-custom) is a community
|
|
built version of Proton.
|
|
GE stands for Glorious Eggroll, the lead developer of Proton GE.
|
|
It often contains fixes for bugs which are not yet included in the official
|
|
Proton releases.
|
|
Thus some games, that do not work with Proton, can be run with Proton GE.
|
|
|
|
## Setup
|
|
|
|
Proton and [Proton GE](#ge-version) can be installed on Linux systems by using the
|
|
[ProtonUp](https://github.com/AUNaseef/protonup) application using
|
|
[Flatpak](../linux/flatpak.md) or the package manager of the distribution.
|
|
ProtonUp is usually bundled in a package named `protonup-qt`.
|
|
It can be used to install Proton GE versions for both
|
|
[Steam](/wiki/games/steam.md) and [Lutris](/wiki/games/lutris.md).
|
|
|
|
## Troubleshooting
|
|
|
|
This section addresses various errors that can happen when using Proton.
|
|
|
|
### Errors with the Wine prefix of a specific game
|
|
|
|
The last ressort for fixing problems that are related to the wine prefix of a
|
|
game is to delete the Wine prefix.
|
|
For this the id of the Steam game first has to be known.
|
|
This is done by navigating to the Steam website or the community page of the
|
|
specific game.
|
|
The URLs will have one of the following forms where the game id can be read:
|
|
|
|
```
|
|
http://steamcommunity.com/app/<game id>/
|
|
http://store.steampowered.com/app/<game id>/
|
|
```
|
|
|
|
After that navigate to the place your Steam games are stored.
|
|
You can remove `<steam location>/steamapps/compatdata/<game id>` to reset the
|
|
Wine prefix completely.
|
|
It is recommended to keep a backup of the folder containing the old Wine prefix
|
|
as it stores game saves and other important data, that can be useful.
