Hi I am using udlfb and it's definitely better than the DRM driver. The DRM driver will crash the kernel if you unplug the device while Xorg is running. The framebuffer driver doesn't crash in this case. (I have a cat and the cat sometimes unplugs cables and I don't want to reboot the system because of it :-) The framebuffer driver is faster, it keeps back buffer and updates only data that differ between the front and back buffer. The DRM driver doesn't have such optimization, it will update everything in a given rectangle - this increases USB traffic and makes video playback more jerky. The framebuffer driver supports programs running full-screen directly on the framebuffer console, such as web browser "links -g", image viewer "fbi", postscript+pdf viewer "fbgs", ZX Spectrum emulator "fuse-sdl", movie player "mplayer -vo fbdev". The DRM driver doesn't run them. If you seach for someone to maintain the framebuffer driver, I can do it.
