Gamemode is enabled but process is not registered with Proton GE

[chenxiex]

Describe the problem
The following error is logged when launching a game with Proton GE.

gamemodeauto: dlopen failed - libgamemode.so: cannot open shared object file: No such file or directory

And querying the gamemode status for the game returns this:

> gamemoded -s77895
gamemode is active but [77895] not registered

Set LD_PRELOAD=/app/lib/libgamemode.so fix this problem.
Running native linux game or using non-proton wine doesn't cause this problem.

Is it reproducible with native Lutris?
No.

Steps to reproduce

1. Launching a game with Proton GE and gamemode enabled.
2. Check the log for dlopen failed error.
3. Check the output of gamemoded -s$GAMEPID on host.

Expected behavior
Game process is registered

Actual behavior
libgamemode.so isn't loaded, and game process isn't registered.

This is probably related to FeralInteractive/gamemode#443. But process registering works with native lutris+proton-ge on my computer.

Set LD_PRELOAD=/app/lib/libgamemode.so fix this problem.

I dont know about your os or de but as I am on arch I am going to tell mine.
Please change the location to LD_PRELOAD=/usr/lib/libgamemode.so

And now if you are playing 32bit game then put this LD_PRELOAD=/usr/lib32/libgamemode.so
And if you are playing 64bit game then put this LD_PRELOAD=/usr/lib/libgamemode.so

NOTE : your location may vary so please check again and then put this in your launch command. And dont forget to enable mangohud also, for eg: LD_PRELOAD=/usr/lib/libgamemode.so mangohud %command%

For me it was showing in on in mangohud but when using the command : gamemoded -s$GAMEPID still shows me active but not registered so ig if mangohud shows it is on then it is working.

This issue is mainly for lutris flatpak, which ships its own gamemode libs.

gamemoded -s$GAMEPID still shows me active but not registered

Most functions of gamemode work even if the process is not registered. However, features like CPU core pinning doesn't work. Unfortunately, pinning is very important for my Intel core ultra 5 125U.

Now in every game it detects that gamemode is active and running, putting LD_PRELOAD=/usr/lib/libgamemode.so in steam launch command. dont know why but it just works.
