These are notes about my Debian Testing, Xlibre, and SonicDE setups. They include technical and visual customizations. To install Xlibre, do the following:

<code>
sudo apt-get update
sudo apt-get install -y ca-certificates curl

sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://xlibre-deb.github.io/key.asc | sudo tee /etc/apt/keyrings/xlibre-deb.asc
sudo chmod a+r /etc/apt/keyrings/xlibre-deb.asc

cat <<EOF | sudo tee /etc/apt/sources.list.d/xlibre-deb.sources
Types: deb deb-src
URIs: https://xlibre-deb.github.io/debian/
Suites: $(. /etc/os-release && echo "$VERSION_CODENAME")
Components: main
Architectures: $(dpkg --print-architecture)
Signed-By: /etc/apt/keyrings/xlibre-deb.asc
EOF

sudo apt-get update
sudo apt-get install xlibre
</code>

Next, let's install SonicDE:

<code>
sudo apt update
sudo apt install -y ca-certificates curl

sudo install -m 0755 -d /usr/share/keyrings
curl -fsSL https://mrchicken.nexussfan.cz/publickey.asc | gpg --dearmor | sudo tee /usr/share/keyrings/NexusSfan.pgp > /dev/null
sudo chmod a+r /usr/share/keyrings/NexusSfan.pgp

cat <<EOF | sudo tee /etc/apt/sources.list.d/sonicde-debian.sources
Types: deb
URIs: https://sonicde-debian.github.io/debian/
Suites: main
Components: testing
Signed-By: /usr/share/keyrings/NexusSfan.pgp
EOF

sudo apt update
sudo apt install sonicde sonic-archive-keyring
</code>

For SonicDE, to get rid of the lock screen default, change the name of the ''Next'' directory to ''Next.bak'' and whatever directory/image you want, make a copy of that one called ''Next'':

  mv /usr/share/wallpapers/Next /usr/share/wallpapers/Next.bak
  cp -ar /usr/share/wallpapers/Arc-Dark /usr/share/wallpapers/Next
  
As for the lock screen default image (Silver sddm mgr), change the following:

  mv /usr/share/sddm/themes/Sonic-Silver/assets/bg.png /usr/share/sddm/themes/Sonic-Silver/assets/bg.png.bak
  cp -ar /usr/share/wallpapers/Arc-Dark/contents/images/2560x1440.png /usr/share/sddm/themes/Sonic-Silver/assets/bg.png
  mv /usr/share/sddm/themes/Sonic-Silver-Light/assets/bg.png /usr/share/sddm/themes/Sonic-Silver-Light/assets/bg.png.bak
  cp -ar /usr/share/wallpapers/Arc-Dark/contents/images/2560x1440.png /usr/share/sddm/themes/Sonic-Silver-Light/assets/bg.png
