Login fails and power buttons are unresponsive on Ubuntu #20

Description

@BenePhetes

Explanation

Environment:

OS: Ubuntu 25.04

Display Manager: LightDM

Greeter: nody-greeter

Theme Version: 1.6.0

Problem Description:
When using the Shikai theme, it's impossible to log in. The theme always reports "wrong password," even when the credentials are correct. Additionally, the reboot and shutdown buttons do not perform any action when clicked. It seems the theme is not communicating with the system's backend services.

Troubleshooting Steps Taken:
I have confirmed that the issue is isolated specifically to the Shikai theme.

✅ My username and password are correct. I can log in successfully using a text-based terminal (TTY via Ctrl + Alt + F3).

✅ Other nody-greeter themes (like Dracula and the default) work perfectly. I can log in and use all the power buttons without any issues when using a different theme.

✅ I tried extensively to configure the theme using /etc/lightdm/web-greeter.yml, including setting the default_user in both the branding: and greeter: sections.

✅ I even rebuilt the theme from the source code after hardcoding my username, but the login and power buttons still failed.

Conclusion:
Based on the troubleshooting, it appears the theme is running in a non-interactive "mock" or "demo" state. It displays the UI beautifully, but it does not seem to be connected to the lightdm backend for handling authentication or power management commands.

Thanks for the great-looking theme! I hope this report helps get it fixed.
