Description Claudio 2024-06-10 20:24:18 UTC 
SUMMARY
I have Plasma 6.1 beta installed (Arch kde-unstable)
After Arch's upgrade to Frameworks 6.3 many systemsettings pages show just a kirigami error message instead of the settings page.
Downgrading the kirigami package to 6.2.1 resolves the issue.

STEPS TO REPRODUCE
1.  Open any of the following systemsetting pages:
Keyboard -> Shortcuts
Sound
Display & Monitor
Bluetooth
Thunderbolt
Printers
Wi-Fi & Internet -> Firewall
Remote Desktop
Wallpaper
Colors & Themes (and all Sub-pages)
Text & Fonts - > Fonts
Notifications
Window Management -> Desktop Effects; Window Rules; KWin Scripts; Virtual Desktops
General Behavior
Search (all Sub-pages)
Application Permissions
User Feedback
Region & Language
Power Management
Autostart
Sessions -> Desktop Sessions

OBSERVED RESULT
An error similar to this one is shown (Shortcuts page for this one):

qrc:/kcm/kcm_keys/main.qml:66 Type Kirigami.InlineMessage unavailable
file:///usr/lib/qt6/qml/org/kde/kirigami/InlineMessage.qml:63 Type KT.InlineMessage unavailable

Or (Colors & Themes -> Global Theme):

EXPECTED RESULT
Systemsettings show actual settings

ADDITIONAL INFORMATION
Comment 1 ratijas 2024-06-11 07:07:16 UTC 
I'm getting that error sometimes, but not all the time, and it's not consistent. I couldn't find a pattern. But Nicolas might know more than me.
Comment 2 David Redondo 2024-06-11 10:08:31 UTC 
Did Qt get an update at the same time?

try removing ~/.cache/systemsettings/qmlcache
Comment 3 Claudio 2024-06-11 18:07:09 UTC 
Hi

I already deleted the ~/.cache/systemsettings folder - that doesn't change anything.
6 days ago the qt5-base and qt5-wayland packages were upgraded, but I noticed the error messages just after the KF 6.3 update yesterday.

Was just testing a little bit more - it also started to get inconsistent like ratijas said:
If I go directly to an affected page (after opening systemsettings) it works and then stays this way, as long as systemsettings is opened.
But if I first click "Mouse & Touchpad" -> "Mouse" and then one of the affected pages, the error message comes up and stays as long as systemsettings is opened.
The following messages are shown in Console when clicking Mouse & Touchpad:

qrc:/qt/qml/org/kde/systemsettings/CategoryItem.qml:31:13: Unable to assign IconPropertiesGroup_QMLTYPE_63 to IconPropertiesGroup_QMLTYPE_63

Comment 10 Mustafa Kamran 2024-06-21 16:31:44 UTC 
I'd like to share my experience. I'm on Fedora 40 KDE Plasma Spin and I also get the same issue. Deleting the qmlcache folder does not solve this issue, but I have managed to find a way to consistently reproduce the bug:

1. Open the System Settings applet
2. Go to "Mouse and Touchpad" section, then go back
3. Go to "Colors and Themes" section and the following error appears

qrc:/kcm/kcm_lookandfeel/main.qml:86 Type NewStuff.Action unavailable

In my computer is always like that, whenever I access the following settings:
Sound, Display & Monitor, Bluetooth, Thunderbolt, Printers, Remote Desktop, Wallpaper, Global Theme, Text & Fonts, Notifications, General Behavior, File Search, User Feedback, Region and Language, Power Management, Autostart and Session, the error will always appear.
Comment 12 Elite 2024-06-22 04:49:38 UTC 
Same issue here on garuda arch kde. 

I tried removing catch an reinstalling  knewstuff, kirigami, qt6-declarative. I have not had a crash so i cant add a report but 

```qrc:/kcm/kcm_firewall/main.qml:152 Type Kirigami.InlineMessage unavailable
file:///usr/lib/qt6/qml/org/kde/kirigami/InlineMessage.qml:63 Type KT.InlineMessage unavailable

I will also provide a screen shot incase that helps anyone.

Comment 16 Adi Efendic 2024-06-22 12:50:46 UTC 
Can confirm the same happens for me. What I did notice is that it usually happens if I visit any settings page after opening System Settings. After that, if I open a settings page directly from the Application launcher (without first opening System Settings) it goes away.

A little more easily readable.
Comment 20 Lunaliz 2024-06-22 15:52:57 UTC 
I updated my system earlier this morning(Arch Linux), there were some KDE updates, and all the problems that I had went away, I am not sure if this was the fix or the system fixed itself, the only KDE related update was KWin's, so maybe was that? Either way, the bug has been fixed in my machine.

In this SS, pacman updating kwin from 6.1-01 to 6.1-03 which *might* have fixed it.

Can confirm kwin? update seems to have fixed it all it takes is a reboot. an its fixed.
Comment 22 Claudio 2024-06-22 16:28:39 UTC 
No not solved with Plasma 6.1 stable or the kwin 6.1-03 package update.

Please read my 2nd comment: https://bugs.kde.org/show_bug.cgi?id=488326#c3 - you first have to click on e.g. "Mouse & Touchpad" -> "Mouse" - than the bug triggers - if you first click on any of the problematic pages, than the bug does not appear.

Comment 29 Nate Graham 2024-07-01 18:11:30 UTC 
There are a few issues here. The one where other KCMs break after navigating to Mouse is actually something different from the issue of KCMs being broken out of the box; that's tracked by Bug 488965, so let's track this separately.

Comment 32 Nate Graham 2024-07-01 18:29:25 UTC 
FWIW I can reproduce the issue of KCMs breaking if you launch System Settings to the Mouse KCM or several others (e.g. Networks) but I'm not sure it was caused by a commit in Kirigami 6.3. I bisected back to the beginning of 6.3 and it always happens. 6.3 might be a coincidence.

Comment 39 Andreas Hermann 2024-07-17 20:18:30 UTC 
This problem is not fixed for me with an update to version 6.1.3. I still get the following error only when navigating first to the "Mouse & Touchpad" KCM and then for example to  "Sound" ("Display & Monitor" and others are also affected):

I can consistently work around the bug by *not* opening system settings via its K-menu link, but using the search (e.g. by typing "touchpad"). See attached screen capture.

Comment 57 Vic 2024-08-05 17:00:40 UTC 
Fedora 40, Plasma 6.1.3

Same issue with touchpad missing options and a bunch of QML errors.

UPDATE: 
There was suspicion of this being involved with Telegram somehow, managed to consistently reproduce it independently form Telegram. 

THE BUG:
Right after opening System Settings, if the first thing you go to is Touchpad settings, it doesn't load and a variety of other subpages in settings give QML errors. 
If you go to and click on any other subpage first, there are no QML errors, and Touchpad settings load properly after that. 

So the core of the issue must be with Touchpad settings page. After failing to load, bricks the System Settings and doesn't let other settings to load properly, too.

Comment 59 Amith M 2024-08-05 17:16:38 UTC 
I think this issue is also linked with some rendering issues. Panels mis-align, and desktop icons behave as if no panels are present.

This mis-alignment issue has be happening since plasma 6. Not sure which bug it is....

Since then i have been using `plasmashell --replace &` to restart plsma to fix the panels. Can you all check if this issue also gets fixed by restarting plasma like this?

I am experiencing this same issue on the same version on Arch as well. In case it's relevant, I am using Wayland, not X11.

To summarize what I have found so far:

If, immediately after launching the settings program, I go to the "Touchpad" page under the "Mouse & Touchpad" category, that page shows as blank. Thereafter, certain other pages show "Error loading QML file". I have not exhaustively determined all the pages that exhibit this error message, but among these pages are the "Display Configuration" page under the "Display & Monitor" category and the "Shortcuts" page under the "Keyboard" category.

Interestingly, for at least some of the pages that display the "Error loading QML file" message, if I instead first go to those pages immediately after launching the settings program, those pages, as well as the "Touchpad" page from earlier, display correctly. I have not exhaustively determined all the pages that exhibit this behavior, but the "Display Configuration" and "Shortcuts" pages from earlier do indeed exhibit this behavior.

I can reproduce this exactly now.

System info (now):
Operating System: Arch Linux 
KDE Plasma Version: 6.1.3
KDE Frameworks Version: 6.4.0
Qt Version: 6.7.2
Kernel Version: 6.10.3-arch1-1 (64-bit)
Graphics Platform: Wayland

Memory: 15.5 GiB of RAM
Graphics Processor: Mesa Intel® UHD Graphics
Manufacturer: LENOVO
Product Name: 82AX
System Version: Lenovo Legion Y7000P2020H

I could also reproduce the bug two months ago (see bug 489022).

System info (at that time):
Operating System: Arch Linux 
KDE Plasma Version: 6.1.0
KDE Frameworks Version: 6.3.0
Qt Version: 6.7.1
Kernel Version: 6.9.5-arch1-1 (64-bit)
Graphics Platform: Wayland

However, I couldn't reproduce the bug one month ago (see comment 51 of bug 487904).

System info (at that time):
Operating System: Arch Linux 
KDE Plasma Version: 6.1.1
KDE Frameworks Version: 6.3.0
Qt Version: 6.7.2
Kernel Version: 6.9.7-arch1-1 (64-bit)
Graphics Platform: Wayland

So maybe this is a regression?

Comment 83 Antoine Pirlot 2024-08-27 14:45:16 UTC 
I have the same issue with the latest version of KDE on Lenovo IdeaPad 3 15ALC6, installed with archinstall.
When following the arch installation guide it works perfectly on the same device and version.

I noticed that after I ran "mkinitcpio -P"  (as root) after installation archinstall process + a reboot fix the issue for all concerned views (even for the empty touch pad setting view).

While using archinstall process, this issue happens and not via the manual installation (using installation guide), I think the archinstall scripts miss this command.

Can someone who can reproduce please run the following:

When it loads:

break QQmlEngine::QQmlEngine 
run

each time it stops type "continue"  

And then let me know how many times it stopped before throwing the error.

However, I can't evaluate https://bugs.kde.org/show_bug.cgi?id=488326#c86, due to my inexperience with `git`.

I took the master kirigami branch and added patch
https://invent.kde.org/frameworks/kirigami/-/merge_requests/1589
After creating the packages and installing them, the touch panel settings appeared.

Here is my timeline (without debuginfod):
- Program is started
- Breakpoint is hit immediately, and the window is not created yet
- After continuing, the window is created, and the breakpoint is not hit anymore
- Click on "Mouse & Touchpad", and the breakpoint is hit again
- After continuing, the breakpoint is not hit anymore
- Click on any module other than "Mouse & Touchpad / Mouse" and "Recent Files", and the breakpoint is not hit (but some error messages will be printed to the console)
- If you click on "Mouse & Touchpad / Mouse" again or "Recent Files", the breakpoint will be hit once again

If you do not click on "Mouse & Touchpad" in the first place (so the bug is not triggered), then "Wallpaper" and "Colors & Themes / Window Decorations" will also hit the breakpoint once.

Confirming this fixed it for me as well. I patched Kirigami release version 6.5.0.

Can also confirm I see the same series of breakpoints as Huanyu Liu above.
Comment 92 Jonathan Isom 2024-08-30 20:21:28 UTC 
I have found that when I first open system settings if I go to one of the panels listed:

Display & Monitor
Bluetooth
Sound
Color Management
Printers
Wallpaper
Global Theme
Fonts
Notifications
General Behavior
Search
User Feedback
Region and Language
Power Management
Users
Autostart
Desktop Session

then to touchpad it works, but if I go straight to touchpad it doesn't open.  I only tried the top item in the sub-menus though, so some may not be listed.

Workaround command for missing touchpad settings:

I run this cmd, then pin it to the taskmanager.  Clicking it brings up the settings window showing the touchpad settings.
The hitting the esc key bring me to the system settings window with the touchpad settings showing. 
Going to the touchpad via the system settings window the section is blank.

Thanks for the fix! Works fine for me with the patch backported to kirigami using openSUSE Tumbleweed 20240905 (Frameworks 6.5).

x11-driver-input-synaptic

In kde6, the x11-driver-input-synaptic package breaks touchpad settings in X.
Here is a photo with the x11-driver-input-synaptic package installed.
This is with the already corrected kirigami package.

And this x11-driver-input-synaptic package has already been removed.

And this x11-driver-input-synaptic package has already been removed.
Written for information.
I didn't know that I needed to remove the x11-driver-input-synapti package from the system.
I will write in the dependencies so that this package is removed from kde6.
