No KMS? No Mesa? Run Wayland Off A Linux Framebuffer!

"Besides needing to get the various tool-kits and other libraries ported to run atop the Wayland Display Server, another requirement limiting the adoption of this X11 Server alternative so far has been the specialized graphics requirements. From the beginning, Wayland was designed for GPU drivers that support kernel mode-setting (KMS), Graphics Execution Manager (GEM) buffers, and OpenGL ES, among some other smaller requirements. Originally only the Intel Linux driver would work, but since then the various branches needed to support Wayland have been merged to their mainline code-bases and it's possible to run Wayland with the open-source ATI Radeon and Nouveau drivers too. But those using the proprietary ATI or NVIDIA drivers have not been able to run Wayland nor those people utilizing the VESA driver or any of the other obscure graphics drivers that lack any of the needed GPU driver capabilities. This though has now changed as it's been proved possible that Wayland in fact can run off a Linux frame-buffer.

"Two patches have been published that first change around Wayland to allow it to be run off a Linux frame-buffer and then the second patch adds a Wayland FB compositor."
