General Config

This section contains the general configuration for EXWM.

(defun jm/exwm-update-class ()

  ; Set default number of workspaces
  (setq exwm-workspace-number 5)

  (exwm-enable))

Randr

EXWM Randr is a built-in plugin that allows you to add two monitor support. By default EXWM merges the two monitors into one making the desktop environment unusable.

(use-package exwm-randr
  :ensure nil
  :config
  (exwm-randr-enable)
  (start-process-shell-command "xrandr" nil "xrandr --output HDMI-1 --mode 2560x1080 --pos 0x694 --rotate normal --output DP-0 --off --output DP-1 --primary --mode 3440x1440 --pos 2560x0 --rotate normal --output DP-2 --off --output DP-3 --off --output DP-4 --off --output DP-5 --off")

  ;; This will need to be updated to the name of a display!  You can find
  ;; the names of your displays by looking at arandr or the output of xrandr
  (setq exwm-randr-workspace-monitor-plist '(2 "HDMI-1" 3 "HDMI-1")))

System Tray

(use-package exwm-systemtray
  :ensure nil
  :config
  (exwm-systemtray-enable))

Volume Control

To control volume through EXWM you can install the pulseaudio-control package.

(use-package pulseaudio-control
  :config
  (pulseaudio-control-default-keybindings))
