I haven't yet understood what is the problem.
LyX has it's own, more configurable fullscreen mode and window managers
have their own generic version, e.g. my WM understand fullscreen as
maximize window and kill all window decorations.
Is your main issue merely that we call it fullscreen and not reading mode?
