Install Requirements for Debian/Ubuntu

(Note: This may not work for all systems, but give it a try!)

sudo apt install -y sddm qtbase5-dev qtdeclarative5-dev qml-module-qtquick-controls qml-module-qtquick-controls2 qml-module-qtgraphicaleffects qml-module-qtquick2 -y

Fix: Login Manager going black randomly by typing or mouse pressing Debian/Ubuntu

If SDDM (Simple Desktop Display Manager) causes the screen to go black when entering input (especially with virtual keyboards or IMEs), apply this fix:

sudo sed -i '1iInputMethod=' /etc/sddm.conf
reboot

This clears the InputMethod variable that might be misconfigured or conflicting, which is a common issue on ARM systems or custom builds.

---

Enable SDDM and Disable Other Display Managers

Make sure only SDDM is active to ensure proper functionality:

sudo systemctl disable display-manager.service ; sudo systemctl enable sddm

Default SDDM background

• To change the default background, put desired image in the /usr/share/sddm/themes/sddm-themes/backgrounds/ folder and add the name of the image followed by its extension (.jpg or .png) in theme.conf file.

• You can also customize it further if you wish in the /usr/share/sddm/themes/sddm-themes/theme.conf
  (blur, form position, etc).
