do you have the fb attached to a tty? (ecore_fb is hardcoded to use
the current terminal)
is your kernel compiled for console fb support?

no, edje depends on ecore, you can use evas without ecore.

yes it is, also etk works on it, several embedded systems do work with it =)

this is the itchy point, i coded the "linux input" system for
ecore_fb, currently it supports only the event devices (/dev/eventX)
so you have to have the kernel support. event devices are some kind of
agnostic so the touchscreen/mouse/whatever arent emulated as a mouse
in kernel (/dev/mouse) , but as a mouse on user level, ecore_fb
supports only relative axis, keyboard and some kind of absolute axis
(i.e touchscreen) but it isnt full tested yet.
