No, that topic is not at all similar.

I write it another (and hopefully last) time: there is no, and never was, an option to suspend in KDM(4).

openSUSE added a patch for that in earlier versions, but that required HAL which is no longer around. That patch was just dropped in openSUSE as well, when HAL had been dropped.
