Following info is > displayed: *** libgtk3 needs an OpenGL or OpenGL EGL backend provided > by mesa3d *** There has been some discussion on the IRC channel today about this question. libgtk3 requires either an OpenGL implementation, or an EGL implementation that provides egl-wayland. rpi-userland provides neither OpenGL, nor an egl-wayland implementation, which explains why you cannot select rpi-userland. Of course, this is our current understanding of what rpi-userland provides, and what libgtk3 requires. If you believe this is wrong and you're able to make things work differently, let us know.
