[SOLVED] Add to Steam Not Working for Linux PC

I am a new Linux user and really like your app. While I do not critically need it, I would like to add some of your games to my steam launcher.
When I click "Add to Steam" in one of my games, the game will not launch. Is there something I can read for troubleshooting because I cannot find a solution online or by videos.
I am on a PC and not steam deck.

Solution

Wine-GE is rather old now (last release is almost a year ago) and thus might not work correctly. Please follow these instructions on using GE-Proton:

Head to the Wine Manager in Heroic, click the "Proton-GE" tab, and install "Proton-GE-Latest"
Head to the settings for your game(s) (icon on game card in library). In the "Wine Version" dropdown, select "Proton - Proton-GE-latest"
Rename your Wineprefix (path is shown in game settings), e.g. from
```
current-name
```
```
current-name
```
to
```
current-name_bak
```
```
current-name_bak
```
. To clarify: Rename the actual folder on your hard drive, do not change the option in the game settings.
Note: This will make game-specific configuration data (e.g. in-game settings or save files) unavailable. If this is an issue, let us know & we'll help you restore them.

Steam must either be closed before you add or restarted after you add

Thank you, but I don’t believe that’s the issue—I’ve restarted my PC multiple times, and it still doesn’t work. I’ve also tried enabling and disabling the "Use compatibility layer" option in Steam, as well as toggling the "Use Steam Runtime" setting, but no luck.

The game briefly shows "Running" in Steam before stopping again.

CommandMC•6/16/25, 5:54 PM

I have even clicked the Steam options to "use compatibility layer"

Don't do that, it won't work. The way "Add to Steam" works is that Heroic is actually added to Steam, with some parameters to stay hidden and only launch the game. This is so save sync and other pre- and post-game launch actions can still happen

Launch Steam from the terminal, launch an affected game through it, then send in the terminal output

Is Heroic already running when you try to run the game from Steam?

skinny-azureOP•6/16/25, 6:16 PM

So I unchecked steam compatibility layer and tried running the game through steam and got the above picture before it just stopped. At least it shows the picture again.

When I open the heroic launcher and then press play on steam it does work. Do I need to have the heroic launcher open to launch it through steam?

skinny-azureOP•6/16/25, 6:16 PM

Also, thank you guys.

nursing-lime•6/16/25, 6:16 PM

You shouldn't have Heroic open. post a log

HeroicBotAPP•6/16/25, 6:16 PM

To help you, we need a game log. Please see the following images on how to get it.

skinny-azureOP•6/16/25, 6:27 PM

So when I laucned via Steam it wont work and then when I open the Heroic Launcher it properly launched so I am not sure if the error will be in that becuase it does work when Heroic is open. May need to try again somehow.

skinny-azureOP•6/16/25, 6:32 PM

I closed heroic and launched solo via Steam and got the banner before it closed again. Went to see if I could somehow get that log and got an error.

CommandMC•6/16/25, 6:33 PM

Click "Show log file in folder" and drag-and-drop the file into Discord

CommandMC•6/16/25, 6:39 PM

Well that looks basically identical

skinny-azureOP•6/16/25, 6:40 PM

could it be this
wine: RLIMIT_NICE is <= 20, unable to use setpriority safely

skinny-azureOP•6/16/25, 6:40 PM

"unable to use setpriority safely" sounds like an error

Bbrilliant-lime Well that looks basically identical

skinny-azureOP•6/16/25, 6:44 PM

Yeah sorry, going to school for accounting, not super awesome with this stuff as you can tell.

dry-scarlet•6/16/25, 6:48 PM

no that's generally something you can ignore

dry-scarlet•6/16/25, 6:49 PM

generally that's just setting some threading priority options on the process

skinny-azureOP•6/16/25, 6:54 PM

Yeah, it isnt a huge deal, I can launch from heroic if i need to. Dont wanna take a huge amount of yalls time,. Could my settings be off by chance b/c I cant really see it being anything else. I just downloaded this thing hahaah

nursing-lime•6/16/25, 7:33 PM

Heroic and Wine are out of date

skinny-azureOP•6/16/25, 8:35 PM

Yep that seems to have done it. thank you guys.

CommandMC•6/16/25, 8:35 PM

Huh, wouldn't have thought that Wine-GE could be causing this

CommandMC•6/16/25, 8:36 PM

Guess that's one more reason not to use it

skinny-azureOP•6/16/25, 8:36 PM

Yeah, tried it on 2 games now and they both launched fine.

skinny-azureOP•6/16/25, 8:36 PM

after I swapped to proton latest

skinny-azureOP•6/16/25, 8:37 PM

i didn't do this segment he listed b/c i didn't know what to rename but i guess i didn't need to
