Hi! To give you my take on your Qs:
1. DirectFB is a lot of fun! 2. DirectFB seems to be very active - most of the traffic is on the directfb-devel list 3. X11 Desktop IMHO you cannot yet substitute DirectFB for X11 - there simply aren't enough apps, the window management is not as good, etc... However, you can run X11 *on top* of DirectFB (XDirectFB) - this gives you the best of both worlds - X11 support, ability to run normal apps, and directfb apps as well. 4. Performance Would I recommend doing this? Well, I think it is worth playing with, and DirectFB is (IMHO) a very good platform for embedded devices. If you leave off X11 the memory footprint is lower, and DirectFB gives you a lot of powerful support for making media apps under linux. Another cool reason to run XDirectFB/DirectFB was true transparency - since DirectFB uses dedicated buffers for each window, real transparency effects are possible. With the introduction of XGL, AiXGL, Beryl, Compiz etc... to X11 this is now also possible under X. 2D performance can be excellent, depending on your HW, but there is little 3D support - and you can't make use of the proprietary NVIDIA / ATI drivers for 3D effects. So it really depends on your application whether DirectFB is faster than X11 or not....
