Currently, only one vt can be active at a time. Directfb applications
usually allocate a vt, then switch to it.  This leaves the other vt's
inactive.

Try to experiment with options like --dfb:no-vt-switch, vt-switching,
no-graphics-vt. Try to do it with directfb apps first, then find a way to
pass these options to mplayer.

Another way is to launch the directfb app while in X.  I have heard that this
setup works for a lot of people.

(Note: I haven't followed development of directfb for sometime, but I guess
those options are still there).
