OpenSUSE MicroOS/Aeon/Kalpa wine/proton issues (noexec filesystem)

[AesaraB]

This was driving me absolutely insane trying to figure out, but if you find this issue then chances are it's not flatpak nor Steam that is your issue.

If you enable proton's debugging and read the log, you'll see something like

0009:err:virtual:map_file_into_view failed to set PROT_EXEC on file map, noexec filesystem?

This is because OpenSUSE MicroOS desktop derivatives (Aeon, Kalpa) have an issue with SELinux's default policy

From the OpenSUSE documentation:

If you run into issues using WINE, and WINE based programs in flatpaks, it is likely due to an SELinux issue, and can be checked by running:

# sudo getsebool selinuxuser_execmod

If that returns 'selinuxuser_execmod --> disabled', you will need to enable it. This can be done temporarily (resets on next boot) with

# sudo setsebool selinuxuser_execmod 1

Or can be set Persistent with:

# sudo setsebool -P selinuxuser_execmod 1
