Steam not running proton games on separate EXT4 partition

I have a multi user system and if possible I'd like to prevent downloading every game 3 times.
Because of that I made a separate ext4 partition for my steam games and selected the partition in steam

drwxr-xr-x 4 root root   4096 May 21 17:06 ..
drwxrwxr-x 2 root steam 16384 May  4 19:59 lost+found
drwxrwxr-x 3 root steam  4096 May 21 17:22 SteamLibrary

All proton games don't launch
I used the launch option PROTON_LOG=1 and the log said this

wineserver: /mnt/steam/SteamLibrary/steamapps/compatdata/1118200/pfx is not owned by you
wine: '/mnt/steam/SteamLibrary/steamapps/compatdata/1118200/pfx' is not owned by you

I know that this is solvable with a

chown -R user:user /mnt/steam

but I don't understand why I need to own the file
my group has every permission

I wanted to ask if it is possible to fake own a mountpoint to multiple users or find some other workaround for this

I can't find anything online because there is a similar issue with having a ntfs partition that's filling my search results.

Re: Steam not running proton games on separate EXT4 partition

Please post your /etc/fstab .

Incase you use a command to mount the partition, what is the exact command ?

The output of

ls -lR /mnt/steam/SteamLibrary/steamapps/compatdata/1118200

would be useful.

this is ls -lR /mnt/steam... tho I don't really get how that would help?

It's kinda weird that there are a bunch of symlinks to proton which is for some reason installed in my home directory?

Re: Steam not running proton games on separate EXT4 partition

Please use [ code ] [ /code] tags for output like that, see https://bbs.archlinux.org/help.php#bbcode

I had no idea whether pfx was  a file or a directory and what it is used for.  The output shows it's like a wineprefix .

https://askubuntu.com/questions/1358075 … ermissions is about a similar case.
The mount line at the bottom of the thread s very different then yours and seems worth a try .

Welcome to Archlinux forums (I forgot to do that earlier)
