Both primary and secondary ssd (internal both) are formatted Ext4 (linux mint)
I am facing this weird issue: Some games, they play flawless when installed in the secondary drive. Some others however, they don’t launch. I have to move them to the primary drive for them to launch and then they work perfect.
How come some games are ok on the secondary drive, while others aren’t? Have you experience this?
Everything I find online points to a drive being NFTS format, but mine are both Ext4, default settings and automounting.
Games that gave problems on secondary drive, but are perfect on primary driver; Ghost of Tsushima, Resident evil 4 and Witcher 3. They don’t launch, and in the case of RE4 it even said my computer had a virus :D or was tampered when launched from the secondary drive (non-sense)


Yes, I have had wierd issues with Steam and external libraries. Mostly because of permissions and non-acsii characters in the path, but some have been unresolved. Steam is really complicated piece of software. The host OS, Steam linux runtimes and Proton all do their part. Flatpak can resolve and cause issues. That being said, external libraries are well tested on the Deck, and should work fine.
First step with troubleshooting would be logs. Check the Steam troubleshooting page on Arch wiki, and Proton Readme on Valve’s github to get you started. You’ll need to add PROTON_LOG=1 to launch options to get a log out of Proton. Also issue trackers for Proton and the linux Steam client are valuable resources.
I hope you get it solved.
I did now, it says Unhandled exception: System.TypeloadException: Could not load type of field ‘InstallerMesage.Form1+…’ due to: COuld not load file or assembly ‘Windows.Foundation.UniversalApiContract, …’ or one of its dependencies.
Does this tell you something?
PS: To clarify it is a rather long text that I get via the terminal when launching said game
