Game Crash on "Create Game" Linux

When I create a custom game the launcher tries to start the game. But it crashes before opening 😞 I am on 5.10.68-1-MANJARO. Can you help me please?

I tried the release 1.6:


and 1.6Beta1:


Hi. I have no idea about linux but your game log shows:
"warning: Can't open lua file "Z:\home%USER%.faforever\bin..\Installed.Prefs"
warning: unable to load Installed.Prefs; using empty initial prefs"

so it seems you dont have a game.prefs file
Did you start the game once from steam?
If not, do so to create a game.prefs file (which safes your personal settings like resolution, hotkeys, templates and os on) and then try again on FAF

Sounds like a problem with wine. How are you running the game? From my experience proton 6.3 works pretty well, and it should be consistent across distros since it uses containers.

@amygdala Thank you for the reply, I did start the game before to create a profile. I started it once more to no avail.

@MazorNoob Thanks for the reassurance, wine is what I understand the least. I am using proton 6.3 from steam and installed wine, wine-mono, winetricks, protontricks 9420 dlls d3dx9 and protontricks 9420 dlls xact. Steam is not a flatpack.

I played two games some weeks ago under 1.4.7 with the lutris installer until it stopped working.

I reinstalled it with the help of tagedas video.
I had to use jdk15-adoptopenjdk

I launch the client with:

export INSTALL4J_JAVA_HOME=/usr/lib/jvm/java-15-adoptopenjdk/

I will try reinstalling wine now.

Reinstalling wine wasn't enough. I will try reinstalling everything tomorrow but first I need some sleep.

I'd avoid installing stuff with winetricks unless you verified things don't work without it, sometimes overrides can make things worse. Try this:

  • Remove FA's wineprefix.
  • Run FA once through Steam to verify it runs and install whatever deps Steam usually adds. In case of issues use protondb, only use winetricks as a last resort.
  • Set launch command in FAF client as needed.


Thank you very much it works!
I removed FA's wineprefix from the location stated in the run file. Afterwards I uninstalled supcom from steam and removed wine, wine-mono and winetricks. I also removed everything from the FAF client, including the hidden files in ~/

I followed the guide from @Usling
and did not have to install winetricks or wine itself manually for supcom to start under Proton 6.3-7.

Afterwards I followed the guide from the wiki.

Last time I forgot to set the launch command in the FAF client, so that was a good hint of you and probably the reason why it did not work in the first place. I think that step is missing in tatsu's video or I missed it.

I am looking forward to play with you guys 😄

Hi All, I'm getting the errors below with my new/clean install.
Ubuntu 20.04: Steam: Proton: SupCom + FA: FA is tested and working like a dream.
FAF Java Client
Java-15-oracle is now Java-17-oracle; 15 has been removed as it is end of life.
I had to edit faf-client and replace 15 with 17 in two places; FAF-client is working and I'm logged in.

Click on a map and create game, create; I get the following errors;

java.util.UnknownFormatConversionException: Conversion = ' '
at java.base/java.util.Formatter.parse(

I suspect this is Java-17-oracle related but any help would be appreciated.

Its not Java-17 related.

I think it fails because your launch command ("Command line format for executable" in settings) is missing %s (this part of the string will be replaced with the .exe location when starting a game).

Thanks Katharsas.

I've changed that field to blank was "PROTON_NO_ESYNC=1 PROTON_NO_FSYNC=1 %command% /windowed 1920 1080"
but still failing to launch FA.

Try inserting path to wine executable between PROTON_NO_FSYNC and %command%.

That’s the wrong command. You need to change the one in the client settings to "%s" not the one in the steam settings


Thank you, however I'm not using WINE. Steam only (with Proton).

Proton is just wine plus some extra stuff, so yea you are using it.


Thank you; I have tried 'blank' and "%s" neither worked.
Just retried, to be sure, and no neither worked.
"Exit code 2"

Thanks for the correction. I thought Proton was Steam/Value's API that could work with WINE, not that it was an extension of it.
Do I need to install wine ? Typing # wine or # wine --help certainly confirms that WINE is not installed.

@Zarrex can you post screenshots of your launch command settings from the FAF client and steam?

All of is kind of confusing for me, there is exactly one location where %s works, which is inside the FAF client settings under "Command line format for executable".

When the client starts the game, it will replace %s with the path to the FA executable. You can modifiy the command so the client adds additional parameters, for example %s /nosound should start the game with /nosound parameter. I have no idea what %command% is so i cannot help with that.

Then there is this part of your log:

/home/andyh/.faforever/bin/ForgedAlliance.exe: 1: MZ����@0��: not found
/home/andyh/.faforever/bin/ForgedAlliance.exe: 1: Syntax error: word unexpected (expecting ")")

Is this really what is inside the log? Its better to post the log as file attachment so we know if this is a forum problem with encoding or if that is actually in the log. Btw the forum uses markdown, so you can use backticks ` to make it clearer when you cite a value.

Hi there, same problem here, on ubuntu(kubuntu) 22.10:

-fresh steam install, which works, with command params: PROTON_NO_ESYNC=1 PROTON_NO_FSYNC=1 %command% (the error is the same if i remove steam additional params)
-faforever installed with linux script
-try to launch a game, the game fails to starts (and in steam it shows that it is still running)
-if i try to run the run-offline executable, it crashes with this error

wineserver: using server-side synchronization.
wine: RLIMIT_NICE is <= 20, unable to use setpriority safely
wine: could not load kernel32.dll, status c0000135

it looks like wine/libraries is missing BUT idk if the offline executable needs to be launched with additional params (eg. PREFIX)

any ideas?

EDIT: i completely removed FA from steam, uninstalled wine and removed the ~/.wine, faforever and faf-linux folders...i rebooted and reinstalled everything from the beginning (steam, proton 7(not experimental) with params, faf-linux) run-offline works correctly and the game starts BUT the lobby still crashed creating a game

EDIT2: after a little bit of digging i discovered various issues with my system..i'll write them here for future users:

-i had a custom repo (ondrej/php) in my system which installed a library (libgd3) version which the amd64 and i386 had incompatibilities between each other (they coundn't be installed together)...i solved by 1) removing the custom repo 2) installing both the libraries needed for my system and wine (libgd3:i386 and libgd3:amd64) 3) installed wine 4) re-added the repo but i pinned/locked the packages installed previously (apt-mark) in their version from the base repo

-at the same time faf-linux creates a local wine prefix in its folder...once the wine installation was broken in the system, the setup script continued to fail until i deleted the faf-linux folder and cloned the repository again (and than executed the script)

in synthesis, on ubuntu 22.04/22.10:
-be sure to install a working wine (32/i386)
-follow the instructions on faf-linux repository
-the game should work perfectly running the run-offline script

i'm still having issues running it from the lobby

I had the same issue as you, and managed to get past it. In my case, it was because had not been executed after my first log in. Hopefully this helps someone else with the issue.

Perhaps you have the same problem. Try running the shell script.

Having this issue as well, exit code 53 really is not very descriptive, for me anyway. @psyrg s post above did not help.

Help? Anyone?
