[Stable Update] 2021-04-18 - Kernels, Mesa, Wine, Plasma5, KDE Frameworks, LibreOffice, Bluez

When you see the SDDM login screen revert to the very old look, it usually means that the SDDM theme that you were using is not compatible with the latest updates to plasma, causing SDDM to show the fallback login screen.

I’m almost sure you would actually have been able to login to your desktop even with that old login screen, and then from there you could have changed your SDDM theme to something that works, or installed from KDE store a newer version of that broken theme. But I don’t know all the facts.

Try using xrandr.
That always works for me.

Still having the same issues that a lot of KDE stuff won’t open after the update. I still cannot open my application dashboard, add widgets, show alternatives, and Kate won’t start either.
Trying to launch Kate from the terminal returns:

$ kate
kate: symbol lookup error: /usr/lib/libKF5TextEditor.so.5: undefined symbol: _ZN9KLineEdit16returnKeyPressedERK7QString

I have seen and tested the workaround proffered here:

In some rare cases you may face the following error on your KDE Plasma Desktop: usr/lib/libKF5KIOCore.so.5: undefined symbol: _ZN4KJob14percentChangedEPS_mNS_14QPrivateSignalE.

wget https://archive.archlinux.org/packages/k/kio/kio-5.79.0-1-x86_64.pkg.tar.zst
sudo pacman -U kio-5.79.0-1-x86_64.pkg.tar.zst
echo "IgnorePkg = kio" | sudo tee -a /etc/pacman.conf

kio has successfully been downgraded to v. 5.79, along with replacing the *git version of it with the non-git version.

$ pacman -Q kio
warning: config file /etc/pacman.conf, line 100: directive 'IgnorePkg' in section 'multilib' not recognised.
kio 5.79.0-1

In hopes of finding a solution, I have read through this thread: Kate don’t start after last update and attempted the solution offered there—which turned out to just be the workaround described above, except for also resolving dependency conflicts—but to no avail. I still receive the above-mentioned error when attempting to start Kate and my application dashboard still won’t open.

Trying to see what the application dashboard itself has to say, I (re-)started the plasmashell from the terminal using killall plasmashell; kstart5 plasmashell. Once I did, I received an output every time I clicked the icon for the application launcher/application dashboard:

file:///usr/share/plasma/plasmoids/org.kde.plasma.kicker/contents/ui/CompactRepresentation.qml:115: TypeError: Cannot call method 'toggle' of null

After a few clicks, it changed to:

file://usr/share/plasma/plasmoids/org.kde.plasma.kicker/contents/ui/CompactRepresentation.qml:115: TypeError: Cannot read property 'toggle' of null

“Show Alternatives…” returns:

"file:///usr/share/plasma/shells/org.kde.plasma.desktop/contents/explorer/AppletAlternatives.qml" 
 "Error loading QML file.\n27: plugin cannot be loaded for module \"org.kde.plasma.private.shell\": Cannot load library /usr/lib/qt/qml/org/kde/plasma/private/shell/libplasmashellprivateplugin.so: (/usr/lib/libKF5TextEditor.so.5: undefined symbol: _ZN9KLineEdit16returnKeyPressedERK7QString)\n"
Alternatives UI does not inherit from Dialog

“Add Widgets…” returns:

file:///usr/share/plasma/shells/org.kde.plasma.desktop/contents/explorer/WidgetExplorer.qml:32:1: plugin cannot be loaded for module "org.kde.plasma.private.shell": Cannot load library /usr/lib/qt/qml/org/kde/plasma/private/shell/libplasmashellprivateplugin.so: (/usr/lib/libKF5TextEditor.so.5: undefined symbol: _ZN9KLineEdit16returnKeyPressedERK7QString)

(I will post the complete output of killall plasmashell; kstart5 plasmashell to my initial support thread: Application Launcher, Add Widgets, Show Alternatives, and others no longer open after update)

I will also mention, as I did in my support thread, that timeshifting back to a backup from 10th April makes everything work once. However, as soon as I reboot that timeshifted system, I’m back to my current issues.

I’m still lost here … Please help me. :frowning:

I got a file like that in my home folder too, what is that?

Had no issue using matcha-sea-dark theme on qt apps in previous updates. now it looks like this

notice how some panes are light-themed and texts are almost impossible to read (using manjaro-gnome)

  1. Please wrap your links in single backticks (`) in the future, until you’ve reached the required trust level to post links. This will cause them to be rendered like this: https://imgur.com/a/JTuji0N. It just makes it that much easier to read and work with the links.
  2. It looks like a descrepency between QT and GTK applications, specifically, it looks like the GTK apps do not have a dark theme, making them stand out. Ensure this is correct.

Hope this helps!

Solved. Thanks!

Me too.

“you would actually have been able to login to your desktop even with that old login screen, and then from there you could have changed your SDDM theme to something that works”

That’s the problem, I cant log in when this broken.

Fair enough.

Gnome, 5.4

After the update I have lost RDP functionality in Remmina. So far I have tried reinstalling Remmina, and various RDP plugins. If I find a solution I’ll post for anyone else that has this issue.

No problem with the upgrade. but can someone help me how to make it so that when I upgrade the kernel to a newer version, the package related to the kernel is also upgraded without having to manually declare it.
In my case, when I upgrade the kernel from linux54 to linux510, I also need to include linux510-nvidia and linux510-bbswitch.

This is the output of the command, no difference when the monitor is connected or not:

Yes, that fixes the problem. The check does not like multiple GRUB_DISABLE_OS_PROBER entries, even if it is just a comment.

Thanks for posting the link to the check. My grub file had two problems. First, I had added a space between # and GRUB_DISABLE_OS_PROBER=false. Second, I actually needed to delete the #GRUB_DISABLE_OS_PROBER=false comment altogether.

Actually the check is faulty, not your config :slight_smile:

I’m having an issue with one of the latest updates…on KDE/Plasma.

This issue presented itself after the 2021-04-09 update. I figured I’ll just give it a couple of days to try to figure it out or maybe an update will roll out. But since there hasn’t any solution out, or I couldn’t find any after looking around. I thought it’s time to make a post, but the thread for the last update is closed, so I’ll post here.

The problems I’m having is when trying to start applications that are dependent on the aom package for AV1 codec.
So far I’ve seen it on digikam, ksysguard, kdenliva and cantata, mpv with celluloid and also having problem viewing some online content.
And the error message I get if I try to start the applications from the terminal is the following:
[application name]: error while loading shared libraries: libaom.so.2: cannot open shared object file: No such file or directory

I have tried to:

  1. Reinstall aom
  2. Removed aom and build/install aom-git
  3. Reinstall the applications that are affected both standard and building git-versions of them.

I have tried to search and find solutions but to no avail.
The only thing that works is downgrading aom all the way to version 2.0.2-1
I did find this bug report for Arch Linux.

This is working for me for now. But long term, this is a dealbreaker, regardless of where the problems lie or who’s fault it is. I need to trust that the media and codecs are working without any stupid problems like this, for my work.

Matchama-dark theme isn’t applying to Manjaro settings manager properly, applied from Kvantum Manager.
Folders is all apps menu (gnome) isn’t transparent. Slight transparent folders looked good.
5.10 kernel is now showing as LTS but not showing as recommended in Manjaro settings manager.
Settings not opening for Desktop icons (ding).
