Customize / replace lockscreen - perhaps xscreensaver

Running KDE on plasma in Debian Trixie.
How can I replace the lockscreen with something else?

  1. how to replace default
  2. What is available. (preferably in the Debian Trixie repos)
    I really liked xscreensaver in under X11

Thank you so much.

Hi! There aren’t user-facing theming or swapping-out options for the Plasma lock screen, due to its security-critical status. Some background on the technical challenges there can be found in this post: Running Screensavers under Plasma6 and Wayland - #8 by jpetso
