Dear Maintainer,
When the screensaver starts, it shows a plain blue background instead of
a wallpaper.
The org.ukui.screensaver "background" key defaults to:
/usr/share/backgrounds/1-openkylin.jpg
which does not exist on Debian/Ubuntu Kylin.
The fallback path:
/usr/share/backgrounds/1-warty-final-ubuntukylin.jpg
is also obsolete.
As a result, no valid background image can be loaded.
The default and fallback background handling should use an existing
wallpaper or avoid relying on distribution-specific hard-coded paths.
