What's with all the global vars...

OK, cool.

This is what I do outside of Emacs (it can be used for Emacs
as well, if the VT is specified) - number 1, tty1 - or, again,
if invoked from Emacs with the designated defun.

The Linux VT / X issue, again, but here not really a problem
since so easy on both accounts. Or so good provided already,
maybe I should say.

last-arg () {
    echo ${@:${#@}}
}

dump-vt () {
    local vt=$1
    local file=$(last-arg $@).png # so it'll also work when $# = 1
    case $# in
        (1) fbgrab             $file ;;
        (2) sudo fbgrab -c $vt $file &&
            sudo chown $USER   $file &&
            sudo chgrp $USER   $file ;;
    esac
}

dump-x () {

    local win_name=$2
    case $# in
        (1) gnome-screenshot -d 5  -f $file ;;
        (2) wmctrl -a $win_name             &&

}

dump () {
    [[ $DISPLAY ]] && dump-x $@ || dump-vt $@
}

and from Emacs:
