That wasn't its real purpose, the purpose was to select the graphics card
to use, the rest was more a case of adding a really separate feature on

You should use -adapter for those cases where without it you only
get a black/green/whatever image instead of video (fullscreen or
not does not matter).

Did you try the -xineramascreen option as I suggested?
Though as said it should default to go to fullscreen on the screen
the window already is on.
