Yes, this seems to be a bug in Emacs (unless the author claims that it is a feature :-). For now, I am using the following piece of code as a workaround (it works pretty well on Linux boxes, but is terribly slow on Cygwin): (with-temp-buffer (call-process "xdpyinfo" nil t) (goto-char (point-min)) (if (re-search-forward "^ dimensions: +\\([0-9]+\\)x" nil t) (string-to-number (match-string 1)) ;; Use 1024 as the default resolution 1024)) > I'd be interested in seeing your frame functions. I have similar > functions that I've built to move the frame from my left monitor to my > right monitor, resize to fit each monitor, and shrink and enlarge each > frame. I did not do many fancy stuffs. All I did was to have different frame configurations for different display resolutions (1024x768, 1280x1024, ..., 1920x1200), and have some key binding(s) to resize the frame in the way I want. The key binding that I use the most is the one that toggles between the normal (default) frame configuration and the "maximized" configuration.

* bug#987: x-display-pixel-width not returning correct value after resolution change @ 2008-09-16 17:43 ` Baoqiu Cui 2008-09-18 18:30 ` bug#987: marked as done (x-display-pixel-width not returning correct value after resolution change) Emacs bug Tracking System 0 siblings, 1 reply; 4+ messages in thread From: Baoqiu Cui @ 2008-09-16 17:43 UTC (permalink / raw) To: gnu-emacs-bug It seems that function x-display-pixel-width behaves a little differently in GNU Emacs and XEmacs. In XEmacs, (x-display-pixel-width) can recognize the display resolution changes after XEmacs is started. For example, if the display resolution was originally set to 1400x1050 when XEmacs was started, (x-display-pixel-width) would return 1400; then, if the display resolution is changed to 1280x1024 while XEmacs is still running, (x-display-pixel-width) would return 1280. However, (x-display-pixel-width) on GNU Emacs is NOT able to recognize such physical display resolution change (from 1400x1050 to 1280x1024) and will still return 1400. I am not sure if this is a bug or feature on GNU Emacs, but I would like to see this function work like its counterpart in XEmacs.
