Pop-OS User missing from Login Screen

After reinstalling Pop-OS on my machine, my login account wasn't visible on the login screen, but it was still fully functional when I entered my username and password. After a good bit of searching, I discovered that the installer had marked the existing accounts as system accounts. Changing them back solved the problem. This is how I made the change.

sudo vim /var/lib/AccountsService/users/<old username>

Change the line that looks like the following

Creating an Oak texture with The Gimp

This guide was created with The Gimp version 2.10.30. It should work largely unchanged with 2.8.x versions. You'll have to adapt it significantly for earlier versions.

1. Create a new image significantly larger (at least 20%) than what you need because this process results in an unusable margin around the outside of the image. I generally create a much larger image and then cherry pick the section that I want for my texture. My image is 3654 pixels wide and 2160 pixels high.

2. Fill the background with the lighter base color for your piece of wood. All of the manipulations that we employ to create the grain will darken this tone. I often use something like #8d6949

Universal Two Factor (U2F) Authentication for Debian 10 Buster

This document describes how I setup two factor authentication (what I know, my password, and what I have, my U2F device) on my Debian 10 laptop. My goal was to provide two factor protection for local login and for sudo authentication. The following proceedure was tested using a Google Titan version T3 and a YubiKey 4.

NOTE: While this procedure is simple, you can lock yourself out of your system if you mistype commands or skip steps. A good way to prevent this from happening is to create another user that you can use to log into your system in the event that your key file is configured incorrectly. This user should have the ability to become the root user (using su or sudo) in order to repair any mistakes that you might make. You might also want to secure one PAM authorization module (sudo, gdm-password
