* exwm-layout.el (exwm-layout--set-frame-fullscreen):
* exwm-randr.el (exwm-randr--refresh):
* exwm-workspace.el (exwm-workspace--resize-minibuffer):
(exwm-workspace-switch):
* exwm.el (exwm--on-ClientMessage):
Calling `exwm-workspace-switch' in bc80eefe does not work correctly
sometimes. This commit improves it by directly specify the geometry info
rather than getting it from Emacs frame.

;;; Commentary:
|
||
|
||
;; This module adds RandR support for EXWM. Currently it requires external
|
||
;; tools such as xrandr(1) to properly configure RandR first. This dependency
|
||
;; may be removed in the future, but more work is needed before that.
|
||
|
||
;; To use this module, load, enable it and configure
|
||
;; `exwm-randr-workspace-output-plist' and `exwm-randr-screen-change-hook'
|
||
;; as follows:
|
||
;;
|
||
;; (require 'exwm-randr)
|
||
;; (setq exwm-randr-workspace-output-plist '(0 "VGA1"))
|
||
;; (add-hook 'exwm-randr-screen-change-hook
|
||
;; (lambda ()
|
||
;; (start-process-shell-command
|
||
;; "xrandr" nil "xrandr --output VGA1 --left-of LVDS1 --auto")))
|
||
;; (exwm-randr-enable)
|
||
;;
|
||
;; With above lines, workspace 0 should be assigned to the output named "VGA1",
|
||
;; staying at the left of other workspaces on the output "LVDS1". Please refer
|
||
;; to xrandr(1) for the configuration of RandR.
