They would be screen lockers, and probably waiting for people to rewrite them using the new infrastructure. See here (all comments) for some background: https://plus.google.com/+SasaRakezic/posts/bcyNtUwHZBq https://forum.kde.org/viewtopic.php?f=289&t=124413

That's just lame. Because screensavers don't fulfill a useful function, they should be consigned to an ignominious death? Let's do the same with all music, art, and literature! Nothing frivolous shall remain! We must all be serious, very serious!

Please re-read. There are real security concern. On the other way, it should be possible to create alternative screen lockers using QML; it's just that no one worked on this yet, which is bad but I can understand the amount of workload already handled by the developers.

There's a good reason why they're gone mainly because... well they aren't really saving anything. Back in the days when everybody had TFT monitors, screensavers would actually prevent the physical damage from literally burning a still image into the monitor's matrix. These days with the LCD displays, they are doing exactly the opposite - keep the PC awake and in turn preventing it from entering a "sleep" state, effectively wasting your power and battery.

The powersaving feature on any modern windowing environment can set a time for the screen to go blank regardless if there is a screensaver on or not.
And what they save is what little bit of sanity I have left. lol
Believe me when I say that I am not inviting an argument. Nor am I trolling. I am just blowing a little steam... One of the things that I find very frustrating under Linux is that most software begins its "gold" phase with half the features missing.
While the screensaver is not the most important feature on the computer, it does provide some amusement on what would be otherwise an intense, highly focused (to the point of obsessive compulsive) work day. It provides a small brief moment of fun. Like I said... it may not save my screen. But it sure helps preserve my sanity.

I get all that (and I remember the days of CRT burn), but I have news for you: there's more to life than electricity. Some of those screensavers are just gorgeous; it's an art form, like demos. I don't care if it's called something else instead; I don't care what goes on in the background to make it happen, but I want to be able to walk into my lab and have those beautiful images take my breath away.

Privacy.
I like a screensaver to lock and hide my screen. Where I work, screen locks are mandated. If I don't have one, I will be forced to use Windows. It needs to be automatic and hide the information on the screen.
I read the Wikipedia article and it points to Security as a reason for screensavers.
At home it keeps little kids from opening hundereds of tabs or windows as one of my kids did when they were younger. I think the count was about 272 windows in Firefox.
So they do serve a purpose. If not screensavers in F22/KDE, I guess I won't be going to F22 until it is sorted out.

Note: Plasma5 *does* include a screen-locker.
However, the screen locker is not a screen saver.

But the point is that those X screensavers did NOT lock the screen in a secure way. Plasma 5 provides a secure screen locker now. It just doesn't do those fancy animations (but only a blank screen with an unlocking dialog), mainly because nobody developed such animations in a way compatible with the new screen locking framework yet. As far as I know, the interfaces (based on QML) are already there, it just needs somebody to write the QML code.

Thank you for the informative post.
Please, how was the present <F22 not locking the screen in a secure way if you can share that information.
Will we still be able to start sessions in other terminals (CTRL+ALT+F[*]) and startx? We use this at home instead of the "switch user".
Just getting around to figuring out why screensavers stopped working on my F22 and found this thread which has all the info I needed (thanks Glenn Holmer for the xscreensaver cheatsheet). I wanted to correct this piece of misinformation, for the archive:

My secondary display is an LG L246WP - 1920x1280 MVA panel (not too shabby) and it definitely burns if I forget to turn off the displays or a screensaver isn't running. I'll come in the next day to find emacs chrome burned into the screen (or the default KDE locker after I found that). :/ My primary (IPS) panel doesn't seem to suffer from this effect.
The good news is that vigorously exercising the LCD elements through all RGB states makes them respond again - the xscreensaver 'flurry' OpenGL screensaver does a great job of this - I can have the screen back to normal in about three hours. Not my idea - the use of flurry for this purpose was written up elsewhere. It was non-trivial to this information, though - many users might assume permanent hardware damage, especially if they can remember real phosphor burn from back in the day.
I'm not sure how the chemistry works, but I am sure that screensavers aren't obsolete on LCD panels, nor should they be considered merely-aesthetic functionality in KDE. If DPMS signalling were reliable under Linux the story might be different, but we've been waiting a couple decades for that to happen and it's still not the situation we have available to us.

You can use xscreensaver if you like:
1) Install xscreensaver and any extra modules you want. This should give you a "Screensaver" entry in System Settings; the command it runs is "xscreensaver-demo", which opens the settings dialog.
2) In System Settings / Startup and Shutdown, click "Add Program" and enter "xscreensaver -nosplash". This starts the screensaver daemon when you log in.
3) Set a keyboard shortcut to transform your screen into a thing of beauty:
In System Settings, go to Shortcuts and click Custom Shortcuts. Click the Edit button and select New -> Global Shortcut -> Command/URL. Name it "Screen Saver"; set the trigger to Ctrl+Alt+S, and the action to "xscreensaver-command -lock".
The only problem now is the butt-ugly xscreensaver password dialog, which is not up to Plasma's high aesthetic standards. Oh wait, Plasma doesn't care about me having beautiful things on my desktop...
