Podman tips

The display manager (DM) is a graphical user interface (GUI) front-end for login information entry, which then often directs to an actual full-fledged GUI.

In this tutorial, we go over some top choices for display managers. First, we go through the hierarchy of displays and GUI options. After that, we proceed by looking at examples of graphical, console, and terminal interface examples of display managers.

For all installation, management, and removal procedures, we use root or sudo privileges. In many GUI cases, a system needs to boot to the graphical.target for a DM to work.

We tested the code in this tutorial on Ubuntu 22.04 (Jammy) with GNU Bash 5.2.15. It should work in most POSIX-compliant environments unless otherwise specified.
