Use the options "no-graphics-vt", "no-vt-switching" and "no-vt-switch"
by one of the following ways:

Pass "--dfb:no-graphics-vt,no-vt-switching,no-vt-switch" to the application,
which doesn't work with mplayer, I guess.

Export "DFBARGS=no-graphics-vt,no-vt-switching,no-vt-switch".

Add these options to "/etc/directfbrc", "~/.directfbrc",
"/etc/directfbrc.mplayer" or "~/.directfbrc.mplayer".
