Weston does not start with "Failed to open device: No such file or directory, Try again..."

g2d-renderer comes from the NXP fork of Weston, customised to work on
their downstream kernels with their libraries. It's presumably looking
for some kind of G2D device node which it can't see for some reason.

If you're using an upstream kernel then vanilla Weston 9.0.0 (with no
NXP patches) works great there on i.MX devices. If you're using a
downstream kernel/GLES/Weston/etc from NXP, then I'm afraid you need
to contact them for support.

Cheers,
Daniel
