Usage

Manual Installation

1. Download the release archive (e.g., .tar.gz or .zip) from the releases page.
2. Extract the archive into your SDDM themes directory (typically /usr/share/sddm/themes):

sudo tar -xzvf ~/arona-sddm-login.tar.gz -C /usr/share/sddm/themes

3. Configure SDDM to use the new theme by editing its configuration file, typically located at /etc/sddm.conf (create it if it does not exist). You can use the default SDDM configuration file as a reference, which can usually be found at /usr/lib/sddm/sddm.conf.d/sddm.conf.

In the [Theme] section, set the Current theme name to arona-sddm-login:

[Theme]
Current=arona-sddm-login

Automatic Installation (Recommended)

The installation script automatically detects and configures the theme resolution for your device.

git clone https://github.com/Eagle10021/Arona-SDDM-Login.git
cd arona-sddm-login
bash install.sh

KDE Plasma Installation

You can install the theme directly from the KDE store:

1. Open your system settings and navigate to the Login Screen (SDDM) section.
2. Click Get New SDDM Themes....
3. Search for the keyword arona and click install.

Testing/Previewing the Theme

To test the theme without logging out or rebooting, you can run:

dbus-run-session -- sddm-greeter --test-mode --theme /usr/share/sddm/themes/arona-sddm-login

(Note: Depending on your distribution, the greeter command might be named sddm-greeter-qt6 instead of sddm-greeter).
