Edit: Thank you, u/solxix@pawb.social, and everybody else who gave some solid advice.

The problem is the drive is mounted with the noexec flag, which is why nothing on it will run. You’ll need to change /etc/fstab to fix that.

I used Gnome Disks to add the exec flag and now everything seems to be working.

I have a desktop PC, not a handheld. When I install games to the secondary SSD, Steam will try to launch the game, then nothing will happen. Lorn’s Lure and some other games give me this message:

Failed to initialize graphics. Make sure you have DirectX 11 installed, have up to date drivers for your graphics card and have not disabled 3D acceleration in display settings. InitializeEngineGraphics failed

Sometimes a third party launcher will attempt an install, but it usually fails. I didn’t seem to have this problem until the last few months. It seems more and more games require installation on my primary drive. Many, but not all games, seem to require a launcher, which may be causing some of the problem.

Every once in a while, attempting to launch one of these games will cause Steam to crash and shut off my wireless gamepad. (GR Wildlands)

Looking for solutions online has been difficult, because most people having this problem have their secondary drive from a Windows install, or is formatted NTFS. This PC was wiped of Windows before the Bazzite install (over a year ago), and the 2 drives in question were bought new, and immediately formatted to BTRFS with no NTFS partitions.

Any help or advice is appreciated.

The following games will not launch from my secondary SSD but play fine on the primary:

  • Divinity II

  • GR Wildlands (also crashes Steam and turns off my wireless gamepad)

  • Icarus

  • RDR2

  • Riven (2024)

  • Roadcraft

  • Robocop Rogue City

  • Snowrunner

  • Transport Fever 2

Here is a selection of games that DO WORK on the secondary drive:

  • Black Mesa

  • Dishonored 2

  • DOOM 2016

  • DOOM Eternal

  • Resident Evil 2
