I'm also not sure here, but I remember hearing that, while the GPU was under Nouveau territory, the display had to be handled with a different DRM driver - the Tegra. That may be the reason.

    As for the NVIDIA question, I believe not. NVIDIA's official driver does not use DRM nor KMS. Another backend for Weston would have to be developed to support whatever-NVIDIA-uses.
    thanks for the answer Kalrish.
    I googled for linux graphics stack and found out that NVidia cant implement a libdrm, unless they open sourced their code.

    Codethink rewrite Weston compositor, but instead of accessing KMS, it access DRM infrastructure?
    Whats that mean? Means that NVidia also can support Wayland in the same manner?
    Please, excuse my ignorance if Im saying too much non senses.

    Does it all mean that we should expect tablets with TK1 and native Wayland running Plasma Active, Nemo, Sailfish and etc.?
