WScreenSavers is a native Wayland screensaver, lock screen and live
wallpaper suite. It ships 23 WebGL/Canvas savers, runs the stock
XScreenSaver hacks through Xvfb, locks the screen with PAM (or hands
off to hyprlock/swaylock) and can run any saver as an animated
wallpaper on wlroots compositors (Hyprland, Sway, River, Wayfire) and
KDE.

This SlackBuild targets Slackware -current, which ships Go, nodejs,
gtk-layer-shell, PAM, xscreensaver and Xvfb. It builds offline from a
vendor tarball holding the Go modules and the frontend's npm packages,
so it is x86_64 only.

Upstream ships a systemd user unit, which is not installed. Start the
idle daemon from your compositor's autostart, e.g. in Hyprland:

  exec-once = WEBKIT_DISABLE_DMABUF_RENDERER=1 wscreensavers --daemon

Optional: wlr-randr (multi-monitor detection on wlroots), hyprlock or
swaylock (external lock providers), rss-glx (more 3D savers).

Upstream shows a support reminder at startup. Delete
/usr/share/wscreensavers/nag to disable it; package upgrades restore
it.

The Noctalia plugin sources are installed to
/usr/share/wscreensavers/noctalia-plugins/wscreensavers. Copy that
directory to ~/.config/noctalia/plugins/ to use it.
