Can't seem to generate proton launch script.

[NaMLiM]

• Which distro do you use?

  EndeavourOS

• Which Proton or wine version do you use?

  Proton-GE9.1

• Do you use pipewire?

  Yes

• What appears to be the problem? (Describe it as best as you can)

  i can't seem to generate the proton launch script on /tmp. i already put PROTON_DUMP_DEBUG_COMMANDS on launch options.

• Did you notice any other unexpected behavior?

  nope

• What did you try already?

  i tried the LD_PRELOAD method and it works. wineasio seems to be running, the problem is when i tinker with patchbay it crashes the game (like the guide said, has high probability of crashes).

• Did you do any of the steps differently or leave them out?

  i believe i have followed all the steps

Try Proton 8.

(Rocksmith has been working fine since at least Proton 4 anyway.)

There seems be a change since Proton 9. This doesn't work on official Proton 9, Proton Experimental and apparently Proton-GE anymore.

I'm currently reworking the non-arch guides and will make one big update.

(I'll close the issue after changing the guide.)

Yes, flag is available in Proton 8 README, but not in Proton 9 README.

Try Proton 8.

thank you it work, now i can play rocksmith on linux using my audio interface.

Okay, I got it working with Proton 9. Basically, I started Rocksmith with the launch options PRESSURE_VESSEL_SHELL=instead %command%. I then ran

# choose your filenames
echo $@ > proton9-launch
echo $(env) > environment

I then put a bunch of seemingly useful environment variables in front, with the PIPEWIRE_LATENCY flag and it worked. I figured out the new variables by running env in a normal terminal and then comparing the output.

Now I need to figure out which environment variables I actually need.

If it turns out that you need a lot, I won't bother with Proton 9.

[theNizo]

Absolute minimum needed variables (only posting the names, pick them out yourself):

SteamAppId
STEAM_COMPAT_CLIENT_INSTALL_PATH
STEAM_COMPAT_DATA_PATH

potentially useful ones

SteamClientLaunch=1
PWD <-- Nope, can't figure out what for
container=pressure-vessel
SteamClientLaunch=1
SteamOverlayGameId=221680 <-- Can't see the overlay either way
STEAM_COMPAT_PROTON
STEAM_ZENITY
SteamEnv
SteamVirtualGamepadInfo_Proton <-- gamepad translation, probably

Please keep in mind that this was just done by trial and error.
