Are you sure fbcon is using your framebuffer? Check lsmod output. If fbcon is using the driver, and your kernel did not crash, then that closed source driver is already implementing all the drawing functions needed by fbcon. If you don't see any output, then there's a bug somewhere or hopefully just an incorrect setting. Check the output of fbset -i and post it here. An incorrect value in one of the settings can easily lead to a blank screen. > > what's wrong? or should i implement my own putc, scroll, etc... or Don't, no use doing this. > better a terminal for framebuffers like jfbterm, fbiterm??? > As a last resort, perhaps.
