i3 is a simple window manager with tiling, floating and other window sorting features. It is lightweight, highly configurable and easy to learn. A dock is integrated and starts automatically to display the workspaces and a tiny program tray. You have only one configuration file, which is easy to understand and modifiable. You don't need to learn any script based programming language like ruby or lua.
- Simple config file
- Uses shell commands instead of script-based languages
- Runs on old hardware
- Drains less battery
- Well documented
You can install i3 using the command
zypper install i3 dmenu i3status
When you start i3 the first time, it displays a popup window, where you can set your modifier key. You can choose between the ALT and the SUPER/WINDOWS key.
