I have this issue if I upgrade swayfx from 0.3.2 (based on sway 1.8) to 0.4.0 (based on sway 1.9).

Exactly the same. It didn't occur to me that it could be swayfx rather than sway.

oh, i forgot that i was using swayfx

You can disable the build-time config check with wayland.windowManager.sway.checkConfig = false if your configuration does not work in the sandbox. You may consider opening an upstream bug with swayfx if config checking always requires DRM device with swayfx.

could be related to WillPower3309/swayfx#313 ?

[amarshall]

No; this issue is not about building swayfx itself.

It works without issue when I set this option,
