Professor Harman:

I think this recipe will do:

1) start emacs with no filename, so you'll visit the *scratch* buffer
2) resize the frame on the first monitor to the size you want
3) enter (frame-parameters) in the *scratch* buffer
4) evaluate the form: place the cursor after the closing paren, and
     type C-x C-e
5) in the resulting alist, there will be cells that show where the top
   and left corners of the frame are: (top . 10) ... (left . 0)
   copy those cells for later use; we'll call them init-top and init-left
6) Drag the frame to your other monitor, and resize it to the shape
   you'd like it to start with.
7) repeat steps 4 and 5; we'll call these cells second-top and
   second-left.  NB: if the second frame is to the left of the first,
   these cells may have a negative number, and + instead of a .

8) add to your .emacs (replacing <bracketed-names> with the cells
   gathered above):

[near the top of .emacs]:

(mapcar
 (lambda (property-cons)
   (assq-delete-all (car property-cons) default-frame-alist)
   (add-to-list 'default-frame-alist property-cons))
 '(<init-top> <init-left>))

 
 [near the bottom of .emacs]:
 
 (make-frame '(<second-top> <second-left>))


On my machine, I get something like this


 (mapcar
 (lambda (property-cons)
   (assq-delete-all (car property-cons) default-frame-alist)
   (add-to-list 'default-frame-alist property-cons))
 '((top . 1) (left . 1)))



(make-frame '((top + -73) (left + -1282)))


Best regards, and don't hesitate to contact me if you have any
problems.

Re: starting up with two frames on different monitors in Mac OS X

[Gilbert Harman]

Dear Mike,

Thanks.  I had to modify your idea, because on my set-up (frame-parameters)
always gives the same results no matter where I drag a frame.  Furthermore I
can't get (make-frame ...) to make a frame in the other display.  But your
suggestion did set me on the right track (or a right track).

 I was able to get things set up by using the right monitor as the main
display, so that frames would appear there by default, but I used trial and
error to get appropriate values for the initial-frame-alist to get the
initial frame on the left monitor.  In my case I used:

(add-to-list
 'initial-frame-alist '(height . 40))
(add-to-list
 'initial-frame-alist '(top . 160))
(add-to-list
 'initial-frame-alist '(left . -1550))

(I tried '(left + -1550) but that didn't work.)  Then I simply added
(make-frame) at the end of my emacs to get the second frame on the right
monitor using the default dimensions (with greater height).

starting up with two frames on different monitors in Mac OS X

[Gilbert Harman]

What can I put in my .emacs so that emacs will start up with two frames, one
on each of my monitors.  I am using Gnu Emacs 21.3.50.1 in Mac OS 10.3.4.

Thanks in advance for any help on this.
