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
- Fonts and Themes
- Window Management
- Panel via Polybar
- Desktop Notifications via Dunst
- Automatic Disk Mounting with Udiskie
- Display Management
- Default Applications
- User Services
- Scheduled Tasks
- Applications
- Desktop Profile
- Notes
- Provide the dw-desktop package
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 Systems.org.
(load-file ".emacs.d/per-system-settings.el")(dw/system-settings-get (intern name))I use 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:
.config/xsettingsd/xsettingsd.conf:
Net/ThemeName "Matcha-dark-azul"
Net/IconThemeName "Papirus-Dark"
Gtk/DecorationLayout "menu:minimize,maximize,close"
Gtk/FontName "Cantarell 11"
Gtk/MonospaceFontName "Fira Mono 10"
Gtk/CursorThemeName "Adwaita"
Xft/Antialias 1
Xft/Hinting 0
Xft/HintStyle "hintnone"
Xft/DPI <<dpi()>> # 1024 * DPI
I also have to do an extra step to make sure Emacs can find the font path from the “desktop” profile.
.config/fontconfig/fonts.conf:
<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
<dir>~/.dotfiles/fonts</dir>
<dir>~/.guix-extra-profiles/desktop/desktop/share/fonts</dir>

I use Emacs as the desktop window manager thanks to the excellent EXWM. This configuration gets loaded relatively early in Emacs startup if running on a Linux machine.

I use 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.

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).

Qutebrowser is a great keyboard-centric browser which uses the Chromium rendering engine via QT 5’s WebEngine component. I’ve configured it to act more like Vimb for window-per-tab behavior that integrates well into Emacs. One thing I like about this browser is that it does a much better job of remembering what windows you had open when it exits so that you can maintain your session more easily. I also like that when you reopen a tab/window, the history of that window is still present.
