Description Tomáš Trnka 2017-09-03 19:40:07 UTC

After installing F26 using the netinstall image with the KDE environment group + a few other groups selected, I have got a system where Plasma is nearly unusable due to multiple issues. All of them are caused by the plasma-lookandfeel-fedora package not getting automatically installed.

However, the /usr/share/plasma/look-and-feel/org.fedoraproject.fedora.desktop/ directory exists and contains just a few scripts belonging to the kde-settings-plasma package. This causes various applications to try to use this theme, even though most of its files are missing, and fail in various ways:

1) KSplash renders only a black screen:
ksplashqml[1589]: No metadata file in the package, expected it at: "/usr/share/plasma/look-and-feel/org.fedoraproject.fedora.desktop/"

2) Krunner does not work at all, pressing the global keyboard shortcut causes the current window to lose focus, but no KRunner window ever appears.
krunner[1684]: No metadata file in the package, expected it at: "/usr/share/plasma/look-and-feel/org.fedoraproject.fedora.desktop/"

3) Locking the session leads to a black screen with only a mouse cursor and no obvious way to recover.
kscreenlocker_greet[4094]: No metadata file in the package, expected it at: "/usr/share/plasma/look-and-feel/org.fedoraproject.fedora.desktop/"
kscreenlocker_greet[4094]: No metadata file in the package, expected it at: "/usr/share/backgrounds/f26/default/standard/"

4) The Logout/Shutdown/etc. buttons in Kicker do not work.
ksmserver-logout-greeter[1245]: No metadata file in the package, expected it at: "/usr/share/plasma/look-and-feel/org.fedoraproject.fedora.desktop/"
ksmserver-logout-greeter[1245]: ksmserver: Couldn't find a theme for the Shutdown dialog ""

5) The "look and feel" KCM does not show any themes, even though Breeze is installed and should be usable.
systemsettings5[3642]: No metadata file in the package, expected it at: "/usr/share/plasma/look-and-feel/org.fedoraproject.fedora.desktop/"

Installing the plasma-lookandfeel-fedora makes all of these problems disappear. I guess that kde-settings-plasma should either require plasma-lookandfeel-fedora  or refrain from shipping a largely incomplete theme.

Versions:
plasma-lookandfeel-fedora-5.10.5-2.fc26.noarch
kde-settings-plasma-26-1.fc26.noarch

Comment 1 Fedora Update System 2017-09-04 14:45:47 UTC

plasma-workspace-5.10.5-3.fc26 has been submitted as an update to Fedora 26. https://bodhi.fedoraproject.org/updates/FEDORA-2017-600e2ffc9b

Comment 2 TM 2017-09-05 15:53:28 UTC

On my fresh installation of Fedora 26, this also seem to affect Splash Screen settings in System Settings -> Workspace Theme -> Splash Screen. Without the plasma-lookandfeel-fedora package, the System Settings application crashes when clicking the Splash Screen icon in the left pane.

After installing the plasma-lookandfeel-fedora package manually the Splash Screen dialogue seem stable and presents its options in the right pane.

I will conduct further tests to see if this also resolves the segfault crashes I've been having with ksplashqml.

Yes! After some initial tests, installing the plasma-lookandfeel-fedora package also seem to resolve the issue when Fedora is locking the screen. If the package plasma-lookandfeel-fedora is not installed, ksplashqml will segfault resulting in a black screen with just a mouse pointer. See excerpt from error below:

Comment 4 Fedora Update System 2017-09-06 14:52:58 UTC

plasma-workspace-5.10.5-3.fc26 has been pushed to the Fedora 26 stable repository. If problems still persist, please make note of it in this bug report.

Comment 5 Rex Dieter 2017-09-22 13:12:03 UTC

Looks like it affects f27, and f27-beta in particular too, re-opening.

Comment 6 Fedora Update System 2017-09-22 13:13:11 UTC

plasma-workspace-5.10.5-3.fc27 has been submitted as an update to Fedora 27. https://bodhi.fedoraproject.org/updates/FEDORA-2017-07b7238be6

Comment 7 Fedora Blocker Bugs Application 2017-09-22 13:14:48 UTC

Proposed as a Blocker for 27-beta by Fedora user rdieter using the blocker tracking app because:

 plasma spin is (likely?) non functional without plasma-lookandfeel-fedora being present, this latest build (re)adds an explicit dependency for it.

Comment 8 Lukas Brabec 2017-09-25 11:01:39 UTC

I was able to reproduce this with Fedora 27 Candidate Beta-1.2.

this (with plasma-lookandfeel-fedora as dependency), fixed the bug.

Comment 9 Kamil Páral 2017-09-25 16:17:21 UTC

Discussed during blocker review [1]:

AcceptedBlocker (beta) - This bug violates the criterion: "Shutting down, logging out and rebooting must work using standard console commands and the mechanisms offered (if any) by all release-blocking desktops."

Comment 10 Kamil Páral 2017-09-27 07:36:26 UTC

This is fixed with Beta RC3.

Comment 11 Fedora Update System 2017-09-27 17:28:09 UTC
