After some recent updates, my XFCE lockscreen (which starts the screensaver) no longer works. The command invoked by the lock screen button, xflock4
, gives me the following error when executed directly.
** Message: 08:06:43.168: Received error message from the locker: GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: Unknown method Lock or interface org.freedesktop.ScreenSaver.
'light-locker-command --lock' exited with status 1
It used to work fine before so I don’t know where I should look into.
EDIT: If I turn on screensaver from XScreenSaver settings’s Preview button, the screensaver works, including the lockscreen part if “Lock Screen after X minutes” is checked.
