I think we tracked down most of the problems to some plasma-5.4.3
packages
inadvertantly depending on qt-5.5.1, which is still currently in f22
updates-testing repo.
Several testers (including myself) confirmed that problems with missing
symbols, like
https://bugzilla.redhat.com/show_bug.cgi?id=1282261
and plasmashell not starting properly are resolved by installing qt-5.5.1
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.
We're hoping others can help confirm that, and provide positive
feedback/karma there to expedite this going to stable updates.
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.
Sorry for the trouble introduced here, we are taking steps to help
ensure
something like that doesn't happen again.
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,
