Thanks for tracking down this issue.  I had noted that "Suspend" was
missing
after applying the Plasma 5.4.3 updates (as well as KDE Frameworks 5.16.0);
moreover, kscreen forgot the Display Configuration (for my dual monitor
setup)
at every logout, and the keyboard layout selector was missing as well.
Also kmix behaved strangely at some point.

Indeed, the issues listed above are now resolved after updating to
qt-5.5.1 from updates-testing:
- Missing symbol issue is gone
- kded & powerdevil run fine
  - Suspend & Clipboard functionality is now working
- kscreen no longer "forgets" the Display Configuration at logout

I updated all qt5 packages listed on the above bodhi page.  Note that some
of these were *missing* on my F22 (which was upgraded earlier from F20),
so I also installed

    python-qt5 and its dependencies
    qt5-qtdoc
    qt5-qtwayland
    qt5-qtimageformats
    qt5-qtquick1
    qt5-qttranslations

at this point, to be on the safe side.

==> Does anyone know if these packages provide essential/required
    functionality for Plasma 5? --
    If so, the upgrade procedure from Fedoras < F22 may need fixing.


Summary of my testing with kernel 4.1.3-201.fc22.x86_64
-------------------------------------------------------
Plasma 5.4.3 is now much more stable, external monitor with nouveau
is working as well, and login is really fast for me!
(I'll retest with kernel 4.2.5 later.)

For completeness, here's the Plasma 5.4.3 announcement (worth reading)
     https://www.kde.org/announcements/plasma-5.4.3.php


Other KDE/Plasma packages installed from updates-testing
--------------------------------------------------------
For the above testing, note that (as mentioned in a previous post)
I also installed these updates to get a usable desktop:

  # dnf --enablerepo=updates-testing update plasma-workspace
  # dnf --enablerepo=updates-testing update kf5*
  # dnf install muon

'muon' was also missing on my upgraded F22 system, not sure
how important it is for Apper (I haven't noticed any difference
in apper so far), probably unimportant for Plasma 5.4.3 ...

For other users out there, please note that I also performed a
clean sweep of ~/.config/, ~/.local  and ~/.kde
(if you do that, please keep a backup), because I had noted that
Plasma 5.4.3 worked much better with a new user account.
However, I cannot point to any specific culprits in my
previous KDE configuration.

No problem, I'm glad it works much better now.

Out of curiosity, which are the current mechanisms to prevent
Qt 5, Plasma 5, KF5 and KDE from getting out of sync?

Do these mechanisms require minor fixes (missing dependencies),
or what kind of steps do you have in mind?

Thanks again,
