No logs at all from Proton

[webaake]

Proton 6.3-8 does not give any logs at all. I've tried with extra commands in steam;
PROTON_LOG=1 %command% and just PROTON_LOG=1
From terminal; PROTON_LOG=1 steam
And from a copied user_settings_sample.py in user_settings.py where I added;
"PROTON_LOG": "1",
"PROTON_LOG_DIR": "/home/myuser/STEAMLOGS",

I have an old log from way before with correct steam appid. But now, nothing.
PS. The new user_settings.py is the same as the sample, except for my addons.
PPS. An I've of course created the dir STEAMLOGS beforehand with my user.

Can you give an example of a game?
When you add anything to game launching options you need the %command% so the actual name of game to launch will be there.

It sounds like you are trying to add this to parameters for launching steam not game launching parameters. And then you are trying to launch steam instead of a game with Proton.

This is from launch options in steam for "my_game":
PROTON_LOG=1 %command% or just PROTON_LOG=1
I do not remember which onet I used the last time I had a Proton log when starting "my_game".
However, I now see that starting with PROTON_LOG=1 steam directly from a terminal might not work for the game.
But, I do not remember putting PROTON_LOG=1 "my_game" in the launch options within Steam for my game. And that's not logical either. I mean I'm already within the launch settings for that particular game (in Steam).

As far as I can see, it has nothing to do with game itself.

Furthermore; this is the exact instructions from protondb.com/help for game settings in Steam;

PROTON_LOG=1 %command%

And it does not work.

This is what it should look like:

After that, press "play" and you should have "steam-.log" in $HOME

[webaake]

Yes, exactly.

And, as I also said, I've used the method of editing user_settings.py as described in the Readme.md file here at Github. No go there either.

Hello @webaake, please copy your system information from Steam (Steam -> Help -> System Information) and put it in a gist, then include a link to the gist in this issue report.

@webaake Have you tried to set the command from the launch parameter as PROTON_LOG=1 PROTON_LOG_DIR=/home/myuser/STEAMLOGS %command% ?

I tested this by creating a custom folder STEAMLOGS in /home/myuser then launching a Steam Proton game.

Steam sysinfo as ordered :) :

Thanks. Besides the fact that Proton might try to render games with the Intel Haswell chipset instead of your NVIDIA card, which shouldn't affect logging, I'm not seeing a hint as to why logs are not being generated.

Just to check, besides the missing logs, games running as expected?

[webaake]

Thanks for your time! I only play World of Warships and it is working as expected. Thanks to Proton! But some weeks ago Wows and Steam just started to crash. That's why I wanted proton logs in the first place. But lately I've figured out that it is Steam that crashes and takes Wows down with it. I've seen that Steam crashes all by itself, as I said earlier. That's been reported to those guys here at Github. But a log by Proton would still be good to have. Thanks again for the work!
PS. Wows seems to go by my Nvidia card. It's the only GPU connected to a screen.

I believe I'm running into the same issue. I've also tried all options above, setting PROTON_LOG=1 %command% as launch option, setting the environment variable during steam launch etc., there seems to be no way to get it to spit out a log on my machine

Interestingly enough I'm also on a Haswell/NVIDIA setup, maybe there's a correlation there.

Hi, is there an update to this?
I am running in to the same problem of not being able to play any titles nor get steam to output any logs. I have tried over 5 games that I can confirm have worked on the same machine before.

I am running steam on a laptop with an AMD iGPU and NVIDIA dGPU.

Hello @Sveske-Juice, AMDVLK has a history of breaking other Vulkan driver implementations. Can you test if removing or disabling it has an effect? If that doesn't have an effect, then please completely close Steam, run steam-runtime from a terminal and see if there's any hints in the terminal spew when you tell Steam to start a game with Proton.

Just found this issue: https://bbs.archlinux.org/viewtopic.php?id=221483

where one said that i could try to reset the steam runtime environment:
$ steam-runtime --reset

this fixed it!. After it was done when opening steam, it will update the environment and then it worked. However i can still not get any logs when setting these launch options:
PROTON_LOG=1 %command%

If you're using the Flatpak Steam, it will be limited on where on the disk it can write to, and you might have to use Flatpak tooling to get it to work. FYI
