EDIT: My problem, was not xscreen2, but rather my monitors in a hdmi/dp setup,
with its input source detection, that was the culprit. not xscreen2, see

This sounds like a similar problem i had with Kscreen2. Kscreen2 would, note
that a 
displayport connected monitor was powered down, then kscreen2, then moved the
windows
 off that monitor and onto other monitors, tripping a event, powering them back
on again.

It could be some USB device. If so it would probably interfere with switched
off screens and the lock screen. There's some guidance in "PC wakes up from
suspend due to USB events".

As the OP I don't have this issue on recent KDE versions, so I'll go ahead and

I just tried a new install of KDE Neon (an Ubuntu base rather than a Fedora
base), set the power saver for 1 minute, and the screen went blank for about 10
seconds, then came right back on again, Same as the Fedora 35 base.

I am having similar issues here with the power saving not keeping the screen
blanked. I can set it to blank the screen (in 1 minute for example), and it
will blank all 3 monitors. They will go blank, even go into their power save
mode for a second, but then everything comes right back on again. It does the
same if I set a shortcut to blank the screen - goes off but then back on again
in about 10 seconds or so. I am using an AMD X3900 X570 system, Radeon RX
5500XT video, 3 monitors (one of them is a different size than the other 2
FWIW) similar to a related report listed under bug 440350. Currently running
the latest version of Fedora 35 KDE Plasma 5.23.4 Framework 5.89.0 kernel
5.15.12-200 and using X11 (Wayland does not work well here - maybe that is a
clue).

Same problem here, running plasma-desktop as part of Kubuntu (was Plasma
5.18.5)  and on top of Linux Mint 20.2 with KDE Plasma Version: 5.18.7. KDE
Frameworks Version: 5.68.0, Qt Version: 5.12.8, Kernel Version:
5.4.0-90-generic.

Regardless of settings made in "System settings > Energy Saving" and regardless
of being on AC or battery, screen is dimmed or turned off at intervals that
seem to be set elsewhere. I filed this as a bug at
https://bugs.launchpad.net/ubuntu/+source/powerdevil/+bug/1942876

Output of `xset q`:

DPMS (Energy Star):
  Standby: 300Suspend: 450Off: 600
  DPMS is Enabled
  Monitor is On

These numbers does not correspond to any of my settings

Disappointed to see this problem is still around after so long.  I had worked
around this by modifying my xorg.conf to disable DPMS, but some recent update
broke this again.  After about 15 minutes, my monitors will blank, shut off, or
whatever it is that's happening, sometimes in the middle of games if it's not
looking at controller input to see if I'm actively using the computer.  DPMS is
still disabled from the last time I tweaked this setting, and it's not working
anymore; even still, KDE should be able to set this itself as per the system
settings anyway.  Current software versions are:

Kubuntu 18.04 64-bit
Plasma 5.12.7
Frameworks 5.44.0
Qt 5.9.5
Kernel 4.18.16-041816-generic

Now on Plasma 5.9.4, I can see in the battery manager applet that Power
Management is suppressed by a tab in google-chrome-stable. The tab doesn't
exist, and Chrome isn't even running (confirmed with ps as root), but hey, at
least now there is some information that explains why the energy saving isn't
working.

I'm suffering from the same issue. The screen power management doesn't work
properly when the screen is locked. This is the log from xset -q:

$ while [ true ]; do echo -n '['$(date +%T)']'; xset -q | grep -A2 Standby |
xargs -I'{}' echo -n ' {};' | sed -r 's/\s+/ /g'; echo -e "\r"; sleep 1; done
# I locked the screen

[13:22:39] Standby: 120 Suspend: 180 Off: 240; DPMS is Enabled; Monitor is On;
[13:22:40] Standby: 120 Suspend: 180 Off: 240; DPMS is Enabled; Monitor is in
Standby;
...
[14:41:52] Standby: 120 Suspend: 180 Off: 240; DPMS is Enabled; Monitor is in
Standby;
# Here I unlocked the screen
[14:41:53] Standby: 120 Suspend: 180 Off: 240; DPMS is Enabled; Monitor is On;
...
[14:42:02] Standby: 120 Suspend: 180 Off: 240; DPMS is Enabled; Monitor is On;
# Flickering between the DPMS is Enabled/Disabled occurs even if the screen is
unlocked
[14:42:03] Standby: 0 Suspend: 0 Off: 0; DPMS is Disabled;
...
[14:42:14] Standby: 0 Suspend: 0 Off: 0; DPMS is Disabled;
[14:42:15] Standby: 120 Suspend: 180 Off: 240; DPMS is Enabled; Monitor is On;
...

It would be really great if this could be fixed.

Well, this problem is back again, for no apparent reason. Simply applied some
updates (kernel 4.7.3) and rebooted, and now monitor power-save / sleep again
does not work.

At some point in the near past, this started working again -- plasma 5.7.3, KDE

Seems to be a different issue. I don't have screen locking enabled, and my
monitors still do not power off.

For some further information, allowing the screen to lock from the power
management settings will wake it back up when the screen locks.

Specifically, Desktop Behavior > Screen Locking is off.  Power Management >
Energy Saving has:
-Screen Energy Saving checked, Switch off after 1 min.
-Suspend session checked, After 2 min Lock screen.

Then the monitor sleeps after one minute but turns back on with the lock screen
after the second minute.

I have this same problem running KDE 5.15.0 (on Ubuntu 15.10) on iMac hardware.
 If I disable screen locking (under System Settings > Desktop Behavior > Screen
Locking), then the monitor will power off as expected with my Screen Energy
Saving setting.  Just having screen locking enabled seems to prevent the power
off from working, e.g. if I tell it to switch off after 1 min and screen
locking is set after 5 minutes, nothing will happen after 1 minute, so it
doesn't seem to be the screen locker re-enabling the monitor.
