Dear KDE Neon users,
I recently apt updated my KDE Neon 24.04 distro.
After rebooting, the KDE session was unable to start.
When I start the session manually (X11 or Wayland) from the TTY console, I get this issue :

$ startplasma-x11 
startplasma-x11: symbol lookup error: /lib/x86_64-linux-gnu/libQt6Qml.so.6: undefined symbol: _ZN23QPropertyBindingPrivate18notifyNonRecursiveERK15QVarLengthArrayI19QBindingObserverPtrLx256EE, version Qt_6_PRIVATE_API

$ startplasma-wayland 
startplasma-wayland: symbol lookup error: /lib/x86_64-linux-gnu/libQt6Qml.so.6: undefined symbol: _ZN23QPropertyBindingPrivate18notifyNonRecursiveERK15QVarLengthArrayI19QBindingObserverPtrLx256EE, version Qt_6_PRIVATE_API

Has anyone else encountered this problem?
Thanks for your help !

I just installed kde neon, but I'm having trouble seeing wifi networks. Has anyone encountered such a problem before?

Ciao a tutti, sto avendo problemi sul mio lenovo con intel icore 7 ultra. Ho installato kde neon, prima avvio ok. Al secondo avvio, non si avvia. L'immagine del sistema solare, non appare. Ho installato in MBR, con /boot/efi (fate32), swap e EXT4. In cosa mi sono sbagliato? Forse devo provare in GPT?

Hello everyone, i just had problem for installation KDE Neon . The first start, was ok. After second start, i don't see KDE neon "solar system". Maybe i am wrong to choose GPT instead MBR? The partition is /boot/efi (fat32), swap and EXT4. Thanks to all

I want to use ICC color profiles with my printer. I believe Ubuntu instructions would get me there. I don't see the equivalent in KDE. How can I use ICC printer color profiles?

Hello there, I was looking for a way to simulate keystrokes like various """gaming""" products have macro functionality built in their hardware. I wanted so badly autokey (autokey-qt in my case, obv.) to work, but the keyboard.send_key("k",repeat=1) or commands with _keys or press_key would not work. The python script is executed when bound to a hot key but it wont do jack shit.

Tried 30 mins with xdotools to bind with a hot key, then remembering this won't work in wayland, then going to ydotools installing ydotoolsd daemon for whatever reason. Guess what, didn't work either.

Going with chatGPT also not helping.

I was slamming my head against a wall for 3 hours straight at this point. Reading thru various forums, manuals and whatnot nothing seem to help. Maybe someone here knows something about it...

KDE Neon 6.2.3 (ubutnu 24.04), Wayland

// inb4: just use X11.
no, i won't use x11, since wayland seems to be a lot smoother than x11 (I have a 165 Hz display set to 144Hz). I am even planning on switching to garuda linux for my desktop tbh. (KDE Neon works flawlessly on my laptop, very cool)

For some context I installed kde neon on to my 2017 mac book pro. I got it mostly working apart from the suspend function when I close the lid since when ever I close it and open it ether the screen is just black or it shows either shows a plug.

Edit: I think I now at least narrowed down the problem with the lid to be problems with both the detecting some triggers in general for waking up after suspension and also the wake up protocol. Since when I woke the macbook up with the power button it 1min to wake up until it showed the windows I had open previously and the system tray before the system tray which is not set to hide disappeared and when I looked at the desktop nothing it was a black screen with only my mouse curser shown.

Edit2: Never mind I was wrong in the previous edit

Hello,

I search a recent graphic tutorial to learn how I can share the 'Public' folder in my home.

I'm in sambashare group.

I have made a right-clic on 'Public' to share and affect sambashare too but I don' see my share in KDE neon and Windows 11 too.

Thanks for your help.

Kills the OS, cannot boot past grub menu. Is this a feature or bug? Using neon-user-20241110-0746.iso, which is the latest "stable" version.

I moved files from Home folder to external USB drive but it got corrupted and I can't access files on the external USB drive. Is there an easy way to recover the "moved" files from the Home folder?

I wanna watch movies in HDR, I got to know that we need something called vulcan layer and mpv to do that. How to add vulcan layer?

i added a new partition and installed kde neon to it on my late 2013 imac, and now whenever i boot it up it turns on linux, i no longer can get into the bios menu by holding alt while booting (i think the bluetooth keyboard can’t connect quickly enough) is there any way to go into bios menu or change the default partition?

UPDATE For anyone else encountering this issue, I was able to solve it by:

Deleting my plasmashell setttings: ~/.config/plasma-org.kde.plasma.desktop-appletsrc and ~/.config/plasmashellrc.

And reinstalling plasmashell:

sudo apt install --reinstall kde-plasma-desktop

I just upgraded KDENeon to 24.04 via the upgrade utility, and all went surprisingly well. The only unpleasant effect has been that the bottom panel has disappeared, and the application launcher will no longer launch (which previously launched via the meta key). In addition, the desktop wallpaper is now gone; the desktop background is simply black.

Task switcher and other meta-key functionality still works. Anyone else seen this, and any ideas as to a fix?

I've tried switching from X11 to Wayland; no effect.

Tried the latest KDE Neon with Plasma 6.2 on a VM today. I must say that the upgrade to 24.04 made the distro a lot more stable and smooth. Not to mention the nice improvements made in Plasma 6.2.

By the way, KDE are also working on Haruna, one of the best video players on Linux. Their Neon repo also has the latest version. I think it would've been perfect if they preinstalled it on their KDE Neon instead of VLC. Thoughts?

Hi, I don't know how to say it better than that.

I have a Legion Slim 5 16AHP9 , with 2 external monitors connected: one to the HDMI, the second to the USB-C PD through a HDMI-USBC adapter.

The internal display is disabled, through settings. The main display is the one through HDMI and extended on the second one.

I have icons-only taskmanager panels on left side of the displays and application menu panels on top side of the displays (with the main having multiple widgets: senzors, system tray, session changer, date-time).

What happens is that both displays, suddenly shift towards the left side by aprox 1/4. Making the panel on main display out of bound and the panel on the secondary display moving on the main display. Basides that the applications start to become unresponsive or displaying glitched graphics on them.

I can fix this issue disabling the secondary monitor and reenabling it.

I am using Nvidia driver 560.35.03, with the graphics mode set to dedicated GPU, from BIOS.

I upgraded to 24.04 release through system update.

Any ideeas what is causing and/or how I can try to fix it?

These are the details of my system

So I have an up to date KDE neon 6 distro and I'm getting a lil pop up that says "Upgrade to the next version" I click the pop up and it opens a window that says "upgrade failed please make sure your system is up to date" yet I have no other updates nor anything pending as in restarts. Anyone getting this same error?

I figured it was time to take the update plunge today, and finally clicked the notification. It fetched very few packages (like 15 or so) and asked if I wanted to update my sources.list from jammy to noble, I clicked yes. It finished the whole process suspiciously quickly, at around 3 minutes, so I rebooted when prompted to - only to realize it hadn't upgraded much at all, because nothing looks or behaves different, and the upgrade notification reappeared.

I tried upgrading again, but now it fails. I tried the upgrade GUI first, then the CLI, but both fail with the same error:

# do-release-upgrade -d
[...]
Updating repository information

No valid sources.list entry found 

While scanning your repository information no entry about jammy could 
be found. 

An upgrade might not succeed. 

Do you want to continue anyway? 

Continue [yN] n

Why is it looking for jammy sources if the target upgrade is noble? Perplexed, I check out /etc/apt/sources.list:

$ cat /etc/apt/sources.list
# Ubuntu sources have moved to /etc/apt/sources.list.d/ubuntu.sources

Ok, let's see what's there, then!

$ cat /etc/apt/sources.list.d/ubuntu.sources
cat: /etc/apt/sources.list.d/ubuntu.sources: No such file or directory

Nothing. The dist-upgrade log at /var/log/dist-upgrade/main.log has the following:

/var/log/dist-upgrade/apt.log contains hundreds, if not thousands of dependency errors, presumably because something went wrong when setting the sources for the upgrade?

Anyone have any ideas? I'm gonna roll back to my most recent backup in the mean time, in case I mucked anything up by running the half-upgrade earlier.

Edit: The contents of my sources.list after rolling back to before any upgrades were attempted:

I asked this on r/Thunderbird and it was suggested that the issue may be a NEON one rather than a Thunderbird one... so...

I just looked at the release docs and it says that auto updates should be released at x.3. According to the release schedule that was passed 1/10/24 and yet I still don't see any option to upgrade on my NEON system (with x.5 at the end of this month).

Does anyone know what the story is here? Really looking forward to upgrading but don't want to do it manually as that's buggered up stuff on NEON for me in the past.

I bought a headset from AOAS that comes with two inputs; one for the headset and one for the microphone. However, when I connect it to my notebook (which only has one input for headsets), it works fine. However, when I switch the microphone from my notebook to the headset microphone, the headset audio stops working and only the microphone works. What could this be?

(I currently use Linux Mint, and I'll go back to just KDE neon when I buy a RAM memory. I've already tested it in live mode and it gave the same result.)

The headset works on my cell phone, and I already have an adapter so I can use the headset and microphone on the same input, but nothing is working, even with the adapter :(

So I've recently installed KDE neon on my desktop computer. Each time I boot up the device, right after the boot menu, KDE neon seems to show me this. Every single time. The first time I almost had a stroke. Why is this? Everything else seems to work perfectly fine.

I (coming from Linux Mint) really want a debian-based distro that has up-to-date KDE packages (Although just having Plasma 6 is enough for me), and has decent support for things like Nvidia drivers, without being too complicated to use as I'm not yet extremely well-versed in Linux.

I was wondering if KDE Neon fit these criteria, and if not what did

I have the understanding that, be it the fault of my hardware, be it the fault of the software, doesn't matter, my Neon System isn't 100% as it should be, but it works well enough.

I couldn't make the update for 24.04, not normally. Do update I used a new ISO and installed over it. The system remained the same but the base was updated. But I noticed one thing, I'm not receiving any updates for Vivaldi anymore. Recently version 7.0 was released and thought about updating the Snapshot install to see the changes. Got the .DEB and installed but... when I went to open it, it didn't. Vivaldi Snapshot doesn't open anymore and I have no idea why.

Makes me feel I'm stuck with the current Stable version (6.9) I have here and I can never update as I have no idea what the problem is.

EDIT: https://forum.vivaldi.net/topic/102776/stuck-at-version-6-9-if-i-update-vivaldi-will-not-open-anymore/18

Vivaldi Sorcerers and Wizards found a solution for the Snapshot not working.

But this whole experience makes me seriously considering abandoning Neon, maybe switch to Texudo. Maybe the source of my problems with Linux is my loyalty to Neon...

I did a fresh install of Neon with Plasma 6.2.2 (ISO date 2024-10-27), but when I reboot after the installation is complete, I just get a black screen. I did format the partitions, so there shouldn't be any old files causing problems. When I searched online, I found an old forum post suggesting that the EFI files might not have been set up correctly,. I tried booting the live environment again and look under /boot/efi on the computer's internal SSD, and there are no files there at all. There are files under /boot/grub though.

Does anyone have any ideas what the problem might be and how to solve it? Thanks in advance.

I do not receive an 24.04 upgrade notification. Is there a way to upgrade manually from terminal somehow?

The KDE community plan an Atomic image-based distro based on Arch. Will development on Neon continue?

The script used by Xpra to setup the sources.list does not recognize Neon's Noble Numbat as an Ubuntu derivative.

I was able to install the packages via the .deb files at https://xpra.org/beta/noble/main/binary-amd64/
