+== ERROR: Unknown dfb pixelformat ==
+osk-sdl is using SDL2 and DirectFB for rendering to the framebuffer (which is what we need to do for most devices, because they only have framebuffer drivers in the kernel, not the more modern DRI/DRM drivers). The error message means, that the SDL2 mode is not mapped to a DirectFB mode. See {{issue|85|osk-sdl}} for detailed instructions on how to patch SDL2 to add a mapping for your mode.
