i3 – Your Silent Window Manager
i3 is simple. i3 is fast.
A window manager for keyboard-oriented workflows.
It doesn’t substitute your desktop environment.
It doesn’t want to be your new GNOME or KDE.
It just helps to build a workflow. For speed. With clarity.
The Basic Tools
As i3 is simple, you have to take care of your tools.
Here is a curated Ghost Operations list of the useful applications:
| Name | Function |
|---|---|
| alacritty | Terminal emulator |
| rofi | App switcher |
| thunar | File manager |
| dunst | Notification daemon |
| copyq | Clipboard manager |
| flameshot | Screenshot software |
| pavucontrol | Volume control |
| arandr | Screen & display manager |
| lxappearance | GTK theme switcher |
| feh | Image viewer |
Install them:
sudo apt install \
i3 \
i3lock \
alacritty \
rofi \
thunar \
dunst \
copyq \
flameshot \
pavucontrol \
arandr \
lxappearance \
feh
Basic Configuration
Start the most important tools and daemons.
Set up the wallpaper.
bindsym $mod+Return exec alacritty bindsym $mod+d exec rofi -show drun bindsym $mod+x exec i3lock -u -c 1c202e exec --no-startup-id dunst bindsym Print exec flameshot gui exec_always --no-startup-id feh --bg-fill ~/Pictures/wallpaper.jpg # Border style hide_edge_borders smart default_border normal 1
Adjust The Display Scaling
To set up the proper display scaling use the Xresources.
vim ~/.Xresources
Add the configuration to this file:
Xft.dpi: 120 Xft.antialias: true Xft.hinting: true Xft.rgba: rgb
In the i3/config enable the configuration:
exec --no-startup-id xrandr --output DP-0 --mode 2560x1440 --scale 1x1 exec --no-startup-id xrdb -merge ~/.Xresources
The output name and resolution depend on your hardware.Xft.dpi affects applications that honor this resource; it does not uniformly scale every application.
Sometimes the screen “tears” while scrolling.
You can install picom, a lightweight compositor:
sudo apt install picom
Create the config:
mkdir -p ~/.config/picom vim ~/.config/picom/picom.conf
Add:
backend = "glx"; vsync = true;
Add it to the i3 config:
exec --no-startup-id picom
Configure The Status Bar
Move the global configuration to your local config and set it up for your taste.
mkdir -p ~/.config/i3status cp /etc/i3status.conf ~/.config/i3status/config
i3status generates the status information, while i3bar displays it.
The bar block in your i3 configuration controls the status command.
Multiple Display Setup – ARandR or XRandR
xrandr --output HDMI-1 --primary --mode 1920x1080 \
--output DP-1 --mode 1920x1080 --right-of HDMI-1
Or use arandr and save the presets.
Workspace Configuration
Inspect window properties and classes with xprop:
xprop
Assign classes to workspaces:
set $workspace1 "1: Terminals" assign [class="Alacritty"] $workspace1
Audio – PipeWire
Install the PipeWire audio components:
sudo apt install pipewire pipewire-pulse wireplumber
NetworkManager
Install the network manager tool to manage your connection in i3:
sudo apt install network-manager network-manager-gnome
exec --no-startup-id nm-applet
Final Thoughts
i3 doesn’t want to be your GNOME or KDE.
i3 is like a nice, modular tool you can build up.
It’s for keyboard-based workflows.
Lean. Fast.
