Millennium [Bug] Games failing to launch on higher proton versions

Before Reporting

[X] I found no existing issues matching my bug
[X] My issue is not caused by a theme

Describe the Bug

When I try to launch some games under Linux, with proton e.g. experimental, 8, 9, and umu (these I tested), the game fails to launch. Not all games, somehow, are affected by this, though. I can launch, from what I checked, most native games and some other windows-only games under proton experimental for example, but not Mount and Blade Warband and others.

Games appear to load, but then they close themselves, without even loading the main menu or anything.

They worked with proton 4.11 though. None of this happens on normal Steam

Expected Behavior

Game launches normally without issue and runs like normal

Steps To Reproduce

Enter Steam with millenium
Try launching Mount and Blade Warband, Orcs Must Die (1 and 2) and some other games with high proton versions
Game does not load

Operating System

Linux

Anything else?

How is this related to Millennium? Does this only occur when Steam is launched through Millennium?

Sep 28 '24 14:09 shdwmtr

like I written, yes, without it I have no such issues, meaning this must be a millenium issue, and themes didnt impact anything

Sep 28 '24 17:09 ghost

Ah, I missed that tidbit near the bottom.

try replacing your start script with this

#!/bin/bash

# This function filters out the error message "from LD_PRELOAD cannot be preloaded" from 64 bit executables 
# The messages are just failing module side effects and not fatal. 
filter_output() {
    local pattern='from LD_PRELOAD cannot be preloaded'
    while IFS= read -r msg; do
        if [[ ! "$msg" =~ $pattern ]]; then
            printf '%s\n' "$msg"
        fi
    done
}

steam_output() {
    while IFS= read -r msg; do
        printf '%s\n' "$msg"
    done
}

exec 3>&1 # Save a copy of file descriptor 1 (stdout) so we can restore it later
exec 1> >(filter_output) # Redirect stdout to filter_output

export STEAM_RUNTIME_LOGGER=0 # On archlinux, this needed to stop stdout from being piped into /dev/null instead of the terminal
export LD_PRELOAD="$HOME/.millennium/libMillennium.so${LD_PRELOAD:+:$LD_PRELOAD}" # preload Millennium into Steam
export LD_LIBRARY_PATH="$HOME/.millennium/${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH}"

# Millennium hooks __libc_start_main to initialize itself, which is a function that is called before main. 
# Besides that, Millennium does not alter Steam memory and runs completely disjoint.

bash steam > >(steam_output) 2>&1 "$@"

See if that changes anything.

Indeed it does, it does not load Millenium this way anymore. If steam is changed back to ~/.steam/steam/steam.sh it loads again of course and of course with the same issue, since that is the same script practically as the one already provided with first setup.

Sep 29 '24 13:09 ghost

I'm not on my linux system right now, but it's possible to figure out what steam points to, it may run other scripts before ~/.steam/steam/steam.sh that are needed with proton.

Sep 29 '24 17:09 shdwmtr

do you mean whereis?

Sep 29 '24 17:09 ghost

No, I talking about what the executable steam does when it runs. I'm relatively sure it runs stuff before ~/.steam/steam/steam.sh. you could probably monitor what scripts are running when you start steam normally and figure it out that way.

I might take a look in the next coming days but I'm pretty busy.

By looking at the logs themselves there are differences in the second part during the runtime of steam.

Running steam with steam command produces this log:

Since the time it was last reported (29 September) the issue has since resolved on millennium version v2.13.1. I was able to successfully launch several games that I had problems with. And so, I find this issue resolved for the time being. Whatever you did fixed it. I have no idea when it fixed, but it works as of this version as I said.

I come here to report that I was not able to launch Among Us through Millenium. I tried multiple Proton versions and launch options from protondb but nothing fixed it. It was only when I tried to launch Steam without Millenium that everything worked perfectly without any launch options or issues at all. I have the proton log from the failed launch attempts through Millenium: https://paste.ivr.fi/azonutetin.mk It may very well be possible this has been non functional for some longer time as I only really play CS2 and that runs natively on Linux.

have you tried my workaround of launching steam first and then millennium? it seems not really related to this but its worth a try
