But such a platform-independent method on X would boil down to using the
same special X module as the platform-dependent method. That is, we
would try running XRANDR in either case ... I don't know about macOS.

But at least on Windows we have to pay attention to such events anyway.

Yes, I know about WM_DISPLAYCHANGE (although we currently only handle the full-screen frames there). But the corresponding X feature requires the use of a special X module, and I don't know what happens on macOS. So I thought a platform-independent method that always works, and can be implemented in just one place, is a better alternative. Besides, adding one more special event comes with minor disadvantages of its own -- one more event to disregard in situations like while-no-input etc.

And on Windows, for example, the "special" API is already there in WM_DISPLAYCHANGE and I suppose the other platforms should be able to handle fullscreen frames after a display change in a similar way too. In either case it's no great deal. I won't implement it because I've sworn to never change the resolution of a running system again (once an xfce Debian here insisted for weeks to come up with a 640x480 screen resolution because it did not trust my monitor's repeat frequency) and master still struggles with the (funcall eldoc-documentation-function) issue. martin

Sounds much too expensive too. If and when the underlying windowing system informs us of display changes, I would just react to them. What's speaking against it? martin

Do we really have to do this on such a low level? Why cannot we call
such a hook from change_frame_size, which would allow us to do that in
platform-independent manner?
Martin, am I missing something here?

This was nine years ago, but this didn't get much attention at the time.

Emacs is now built with xrandr support by default (on the relevant

But looking through the code, it doesn't seem like Emacs has grown this
capability over the years? But I may be looking in the wrong places.
In any case, it sounds useful? I haven't tried applying the patch,
though, so I don't know how much work that would be to bring it up to
date.
Anybody got any opinions here?

On MS-Windows there's the WM_DISPLAYCHANGE message sent to the message pump. Emacs already accepts that message (see w32term.c), but currently does nothing with it except announcing the change to the attached debugger. However, on Windows the message also specifies the new resolution, so this: > + inev.ie.kind = SCREEN_CHANGE_NOTIFY_EVENT; > + inev.ie.frame_or_window = XCAR(dpyinfo->name_list_element); is not general enough: there should be a way to provide the new dimensions to the event queue. It also means that a "normal" hook is insufficient to handle this event, it should be a -functions style hook.

Content-Type: text/plain; charset=UTF-8; format=flowed
Content-Transfer-Encoding: 7bit
Severity: wishlist
Raised by Edward O'Connor in emacs-devel thread [1], filing in
bugtracker so it doesn't get lost over the feature freeze period.
Emacs doesn't appear to currently provide a hook that is reliably called
when the _display_ geometry changes on graphical window systems. e.g.
screen resolution changed by user, monitor hotplugging.
Emacs frame/window geometry might sometimes be considered to remain the
same by the window system terms despite changing overall display
geometry, so e.g. window-configuration-change-hook is not always run
when the display geometry changes.
Attached is an initial x11-only stab at an implementation that calls
window-configuration-change-hook when display geometry changes, though a
separate hook would be another design option.
For ns, Edward also mentioned:
"On GNUStep and Mac OS X, applications can listen for
NSApplicationDidChangeScreenParametersNotification for this sort of thing"
Dunno about w32 as yet, but presumably it has something similar.
