Can one run DirectFB with a card that doesn't have a direct driver? AFAIK
You can still use vesafb with the generic software renderer, but you will lack most hardware optimizations, specialy pixel format conversions.
only Matrox cards and some Epias really work with DirectFB, others have no drivers. I fought quite a lot with DirectFB about a year and a half ago when it was investigated for another purpose, but in the end DFB
There is an ATI driver since this time, I think. And DirectFB improves regularly.
didn't really work too well (and that was with a more or less supported CLE266 chip). Somehow DFB also felt a bit heavy and CPU intensive compared to using normal X11.
DFB must be way lighter than X. In my case, it is nearly 80MB RAM less (counting X + Xine - softdevice). CPU utilization depends on hardware acceleration, WTR MPEG2. Nothing should impact CPU in DFB per se.
