You will have to
override
the minibuffer default frame configuration.
Assuming you want to change the height from -98 on any machine to -1
(screen bottom) on screw, you may add this lisp to your
.emacs
:
(defvar my-minibuffer-frame-alist (list '(name . "Minibuffer") '(minibuffer . only) '(height . 1) (cons 'top (if (string-match "^screw" (system-name)) -1 -98)) '(width . 180) '(left . 190) '(user-position . t) '(auto-raise . t)))
