From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

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

Well, technically Steam expects a file system to act as a Linux file system. Since some features that Linux file systems support do not exist on NTFS, it doesn't work correctly.

By the way, if you're gonna use Proton for a game, you can backup and reinstall it by using that backup on Linux. You don't have to download it again.

no thats the thing, steam works without a problem. it is only when i do it NOT through steam where i get issues.

but i play mainly on windows anyway, i just wanted to try it out a bit out of boredom and got surprisingly good results.

i just wait how the windows kernel restrictions influence kernel level anti cheat, and depending on the result i may switch to full linux again if kernel AC breaks and devs are forced to use "normal" AC again
