Game not starting on Ubuntu

[midnight owl]

Asking for a friend here. They've recently switched to Ubuntu linux but whenever they launch the game it closes shortly after.
We've tried several combination of launch options/proton versions from protondb but nothing has helped so far.

[deep storm]

experimental version of proton too? (heard that fixed it for one user)

[midnight owl]

Yeah that hasn't worked either.
Currently using Proton Experimental with no launch options.

[deep storm]

could you find logs? (or ask the friend to hop in here and get the logs)

[midnight owl]

Will do

What folder would the logs be in?

[deep storm]

idk how linux handles it but the equivelent of %userprofile%\AppData\LocalLow\10 Chambers Collective\GTFO, then id say grab a screenshot from there

[midnight owl]

This is the only log we could find

try verifying the game install

@sudden lantern you cant find anything else in here?

[midnight owl]

So we verified the game files and tried to launch again but got the same issue with an identical log

So far its a GTFO specific issue, multiple other games have managed to launch including other unity games.

[midnight owl]

We tried something a little experimental.
My friend has changed to PopOS since we thought maybe a fresh install of the os would give us some headway. Unfortunately its still the exact same problem.

The game ran just fine on Win11 on their machine, so its strange that we're getting this issue while others seem to be able to run the game on linux fine.

[deep storm]

gtfo on linux has been a bit funky

[sudden lantern]

This is normal as far as I know

So dw

hey @midnight owl, I've got a friend who had a similar situation earlier and we told him to go through the proton versions. it was proton version 9 that worked for him. Idk if it would be a definitive fix for you, but it's worth a shot if you haven't tried.

I've also (i think) stumbled upon the locallow directory in linux. I'm using CachyOS, so i'm not entirely sure if it's the same for you. If you do find it there though, have a look at #bug-reporting and see what you can find/send.

[midnight owl]

Oh my god lmao, this worked.
Funnily it was the first one he tried 9.0-4

[quaint parcel]

nice

i still wonder if that path is valid

[midnight owl]

yeah that path is very similar to the one we found the logs in

i don't remember the exacty directory but it was identical after your ./steamapps

[quaint parcel]

that's interesting that that's the only log that you found there, because i saw a bunch of txt files in that path on my machine. but i haven't had any issue on linux other than switching to other proton builds when they became a problem, and i've never had a problem playing on windows.

[sudden lantern]

thanks for the help
