Just for a recap, when is Wayland expected to support accelerated OpenGL (not the ES kind, the full thing)?
I don't think anyone is planning that right now, although it wouldn't be hard. I think ES2 is basically a subset of GL2, which throws out all the legacy/fixed function parts.
The mesa drivers support ES2, and I think both NVidia and AMD do as well (or at least they have that ability for some of their drivers), so I'm not sure there will be any reason to support regular GL2, but if it becomes an issue I bet someone will fix it pretty quickly.
Somebody correct me if I'm wrong, but I thought that the problem was that libGL from Mesa was heavily tied to X, and cleaning that is quite an undertaking.
It just seems funny that people are complaining so vocally that OpenGL 4 apps don't run on Linux (there's 2 of them. TWO!), yet get excited about a system which does not support basically any existing native OpenGL software.
