This file contains configuration for my overall desktop environment. My workflow is driven by Emacs but there are still a number of applications, tools, themes, and fonts that I must install to have a complete desktop experience.

* System Settings
Load system-specific settings from =.emacs.d/per-system-settings.el= and unpack relevant values into blocks so that they can be used in configuration file blocks. These settings are configured in [[file:Systems.org::*Per-System Settings][Systems.org]].

* Fonts and Themes

I use [[https://github.com/derat/xsettingsd][xsettingsd]] as a minimal settings daemon for Xorg applications. It replaces similar daemons from desktop environments like GNOME and XFCE and enables me to use a simple configuration file like the following:

I also have to do an extra step to make sure Emacs can find the font path from the "desktop" profile.

I use [[https://github.com/polybar/polybar][Polybar]] to display a panel at the top of the primary screen to display my current EXWM workspace, CPU usage and temperature, battery status, time, and system tray. It uses some custom hooks back into Emacs via =emacsclient=.

* Desktop Notifications via Dunst
742
[[https://dunst-project.org/][Dunst]] is a minimal interface for displaying desktop notifications. It is quite hackable but I'm not currently taking much advantage of its power. One useful feature is the ability to recall notification history; the keybinding is =C-`= in my configuration (though I'd prefer if I could invoke it from an Emacs keybinding somehow).
