i3 is one of the most popular and well documented tiling window managers available for Linux. It comes with it’s own status bar, screen locker and menu, with very sane default configs that are easy to edit and add to. i3 is very lightweight, making it great for everything from older PCs, all the way up to super-performant workstations. The steps below work well with an Ubuntu 24.04 Server installation, and will install i3 with my custom configurations and theming, along with a good base set of applications. The default configuration is for use with HiDPI monitors (192 dpi settings) and desktop-type computers, but there are options at the end of the script that let you change to 96 dpi settings for use with non-HiDPI monitors, and/or change to laptop-type (battery powered) computer settings.
Step 1: Install Git (it may already be installed)
sudo apt install gitStep 2: Clone my custom scripts
git clone https://git.sr.ht/~e33io/scriptsStep 3: Change the directory to the scripts directory
cd scriptsStep 4: Run the i3 script
sh ubuntu-srvr-post-install-i3.shStep 5: At the end of the script you will see the option below, and answer n (for no) to keep the default HiDPI settings or y (for yes) to change to non-HiDPI settings
NOTE: The configs that were installed with this script are based on using HiDPI monitors (192 dpi settings). The option below lets you change to 96 dpi settings for use with non-HiDPI monitors. --------------------------------------------------------- Do you want to change to 96 dpi non-HiDPI settings? (y/n)
Step 6: After the option above, you will see the option below, and answer n (for no) to keep the default desktop-type computer settings or y (for yes) to change to laptop-type computer settings, then you will see “All done, you can now run other commands or reboot the PC” when the script is finished
NOTE: The configs that were installed with this script are based on using a desktop-type computer. The option below lets you change to laptop configs for use with a laptop-type (battery powered) computer. --------------------------------------------------------- Do you want to change to laptop configs? (y/n)
Step 7: Reboot the PC
