For fbdev backend there is only one hardcoded name (as there can only ever be one output and that cannot be hotplugged): "fbdev". I suppose we have forgot to document that, but then again, the whole fbdev backend is undocumented... > As I'm no Wayland/Weston expert I want to use backend/renderer that > works.

It will all be apparent in the Weston log, which it by default prints to stdout/err. Note, that if stdout/err is the same VT in which Weston will show up, you have to redirect to a file to see the log. > I guess with this DRM/etnaviv I might be able to get Weston 2.0 work > as it fixes one annoying bug.

Is it the EGL support that was ripped out? I think with etnaviv you should aim for DRM-backend with the GL-renderer, which is what you will get by default. The issues I have heard of are with Wayland clients, so ensuring apps do not use hardware accelerated GL should get you going immediately. If that doesn't work for some reason, then DRM-backend with the Pixman renderer (--use-pixman command line argument) is the next best thing, avoiding the GPU completely. Fbdev falls far beyond in features. Thanks, pq
