Dpms

Since Clightd 5.0, Dpms API exposes 3 different plugins (priority-listed below):

• /org/clightd/clightd/Dpms/Xorg
• /org/clightd/clightd/Dpms/Wl
• /org/clightd/clightd/Dpms/Drm

When calling any of those, their plugin will be used; when calling main object path first available plugin will be used instead given the above priority-listed list.

Note that Changed signal will be sent on both main object path and used plugin's path.

The API is the same for any of those plugins; but first 2 input parameters ("ss") meaning changes:

Xorg

• $DISPLAY
• $XAUTHORITY

Wl

• $WAYLAND_DISPLAY
• $XDG_RUNTIME_DIR

Support on wayland requires the compositor to implement org_kde_kwin_dpms protocol.

Drm

• card (if empty, defaults to first drm device it finds)
• unused
