So, I discovered weird behavior when trying to play games on an NTFS file system in Linux.

When i auto mount the drive through a fstab entry, it is only able to launch Linux native games (I think I read somewhere that this is a permission issue).

However, if I mount it through steams “select a drive” option, it works without a problem (so far at least).

I assume this is again a permission issue, as when I mount the drive through steam, I get a Polkit password prompt.

Anyone got a clue what’s going on, and/or maybe a way to make the auto mount work, so I don’t have to manually mount it after every boot?

Distro:

Arch

Kernel (according to neofetch):

6.11.1-zen1-1-zen

NTFS driver:

ntfs-3g

Proton version:

GE-Proton9-10

tested games:

  • Terraria (Tmodloader)
  • Project Wingman
  • Hades II

fstab entry:

#/dev/nvme1n1p1

UUID=E01A2CEC1A2CC180 /mnt/games ntfs nofail 0 3

full system update a few hours ago

    Not really, because some files in the wineprefix will have invalid names.

    When an NTFS volume is mounted, it implicitly uses the windows_names option, which restricts the character set that can be used in filenames, in order to preserve compatibility with Windows. The specific character in question is the colon – it is permitted by NTFS, but it’s a reserved character in Windows, which means it is also restricted by the windows_names mount option. This prevents Wine from creating its c: and z: symlinks, which are required for Wine to operate.

    You could try some symlink fuckery, like linking .../steamapps/common to the NTFS drive, since all of the problematic files are located outside of that, in .../steamapps/compatdata. Or you could mount the NTFS volume directly to the common directory. If you do, I’d love to hear the results.

      That makes sense. Thanks for the detailed reply.

      Though you could ask this to OP, they might try it. Personally I don’t use NTFS even on my external HDDs.
