Weston does not have code specific to Nouveau, but it did go through extensive changes to the DRM-backend between 4.0.0 and 5.0.0. The error itself is the most surprising to me: EGL says it's using Nouveau, yet "failed to create kms fb: Invalid argument". It is as if Mesa/Nouveau allocates buffers that the kernel DRM/Nouveau driver cannot use. One would have to look more closely on what happens there, is Weston fumbling some buffer attributes, or is it a bug in Nouveau that just got exposed by using EGL/GBM/DRM little differently. The only tangible suggestion I can make is to bisect Weston and see which commit breaks things for you. Thanks, pq
