How do I uninstall old versions of Proton?

[test]

I got 5 different versions of Proton I see under steam/steamapps/common in my Linux Mint. I assume I don't need all 5 to play my nonlinux games?

How do I uninstall 4 of them? They are taking up alot of space. I don't see these installs under Software Manager or Package Manager, but maybe because they are part of Steam?

If some games need the older versions to play, how do i determine that? How do I tell what games are using what Proton? Is it possible to try a different proton to see if that would work as well? Or does the automatically selected proton always the best and newer protons typically don't gain backwards compatibility?

Uninstall them like you uninstall a game.

On the left side column, below the "Home" tab and above the search bar where it says "Games," click on that and check "Tools".

Search for for Proton and uninstall the ones you don't need anymore, though I suggest, you make one backups each of version 3 and 4 since those can be useful for old games.

Sometimes you do!

They take up about 13-14 GB of space on my side. I personally wouldn't delete them. You can go to your steam games folder (/steam/steamapps/common/ or something like that) and do that. I don't know if they will be installed later again or not.

You can even add other proton versions to ~/.steam/root/compatibilitytools.d directory (https://github.com/GloriousEggroll/proton-ge-custom)

Hope that helps!

Is all the files of a proton install in the common folders? Is there a proper uninstall method other than just deleting folders?

The "proper" method is the one stated in the first reply here. Search for "proton" in your game library and uninstall as you would any game, keeping those which you actually use. Also that glorious eggroll proton suggested has proven useful to me in the past for some games.

I followed and read the links provided by PMI, none of them answered the question of how to tell what installed games are using what Proton version.

If you check https://www.protondb.com/ there are suggestions what version works.
on the github of proton https://github.com/ValveSoftware/Proton/ you can ask question specific to proton and check for suggestions as well.
Proton is still under delevelopment.

Grrr, you aren't properly reading my posts.

I want to know what installed games are using what Proton version. Not what proton versions are suggested for what games, what is actually currently being used by what within Steam! This is a Steam question, so I should not need to go ask on github, they'd likely be less equipped to answer a question about the Steam launcher anyway.

If you have Enable steam play for all titels and did not specify what version of proton to use it always uses "proton experimental" if you specify it will use that version. And If you right click on any game and select "properties" and mark "compatibility" and there selected a custom proton version i.e "proton experimental", "5.13-6" and so forth it will use that version of proton,

If I don't specify "proton experimental" it uses it if I specify "that versionl"? HUH???

in steam - setting - steam play you have options to "choose use steam play for all titels" If you have that checked it will default to "proton Experimental"

If you right click a game, any game and select properties - compatibility where you can see what proton version (if any) you are using.

Check those places to know what proton version your games are using. Remove and reinstall proton versions from tools if you need to. Oh, yeah, under tools the proton version that is installed is white the others are gray.

in linux guides

i have written a script which will try to determine the compatdata proton version
caveat is that the game must have been last run using that version of proton

https://steamcommunity.com/sharedfiles/filedetails/?id=2182049348

as it stands, steam has no way to identify which games are compatibility set for versions of proton

its not good, its a nightmare


if your games are all updated
you can manually delete the files of the offending proton
close steam, open steam
and the games that are selected for that offending proton will require an update (download proton)

the OP is asking how to find the game that WONT let you uninstall proton

most comments here are not helping this issue.

[catbox]

for now, i keep these proton versions installed for testing etc:

4.11
5.0
5.13
and proton-ge-5.9-st

[test]

When i try to uninstall Proton 3.16 and 4.11,I get this

Also 5:13 said it was taking like 9gb, but removing it seems to only have given me like a gb or so.

One or more games is configured to use that version, maybe something from the whitelist.
