[SOLVED] Bazzite: Steam won't launch games from ext4 secondary drive (lemm.ee)

I finally took the time to move my gaming rig to Bazzite because I don't boot it that often, and because I don't want to spend half the little time I have for gaming doing updates and maintenance.

Most of my games are on an ext4-formatted secondary drive. Note: They worked perfectly on Manjaro and Nobara, the previous distros I used on this machine.

They are recognized by Steam, I can install and uninstall games just fine, it's just that... they don't launch. At all. Native or Proton. Like if I was on an exFAT partition. The "Launching" button switches back to "Play" almost instantly. If I move a game to my main home partition, it launches fine.

Has anyone encountered this issue before?

Where/how could I get detailed logs to try and pinpoint the issue?

Thanks!

Edit: Solved! The issue was with fstab configuration, always specify exec AFTER users, despite the doc telling you that order doesn't matter ;)

Wrong fstab entry :

UUID=blah-blah-blah /my/mount/point ext4 defaults,noatime,nofail,auto,exec,users,rw 0 2

Proper fstab entry (it's subtle):

UUID=blah-blah-blah /my/mount/point ext4 defaults,noatime,nofail,auto,users,exec,rw 0 2

I assume your drive in fstab (or systemd mount, whatever your setup is using) has the 'defaults' permission option? If it doesn't that may be why games aren't launching. Also exFAT doesn't have the proper Unix permissions to launch games iirc.

The issue was indeed from the fstab. But it was because exec was specified before users.

Late to reply, but you should just leave it as defaults,noatime,nofail. From the mount man page, defaults already implies rw,suid,dev,exec,auto,nouser,async.

EDIT: change it to rw,suid,dev,nouser,exec,auto,async,noatime,nofail actually, anything after defaults overrides the options specified by that.
