Today I updated KDE neon on my desktop, after a while

After I restarted the system and the updates were installed (no errors), I found KDE broken

Window title bars and borders are gone. Just missing, for any and all windows

Like this:



Everything else seems normal, but the system became unusable

What could be happening here? I have no idea where to begin to debug this and I really dont wanted to reinstall the OS now

Any help will be much appreciated

Same thing happened to me. When updating through discover it told me that it would need to delete 'kwin-x11' to install a bunch of packages. Against my better judgement, I still installed the updates.

I haven't had any problems with the Wayland session, so you can log in to a Wayland session on the login screen. Hopefully this gets fixed soon..

This is the same issue described here: viewtopic.php?f=309&t=174973

Until they release these 32-bit packages, `sudo aptitude install kwin-x11` might help. But you'd best say "no" to its plans until it shows one you can live with. (It's gonna show different combinations of packages it can remove or downgrade to make it work).

I wish Wayland worked with me…

Hello everyone, the same problem happened to me today. If I try with "sudo aptitude install kwin-x11" I get this:

Code: Select all

Alcuni pacchetti non possono essere installati. Questo può voler dire
che è stata richiesta una situazione impossibile oppure, se si sta
usando una distribuzione in sviluppo, che alcuni pacchetti richiesti
non sono ancora stati creati o sono stati rimossi da Incoming.
Le seguenti informazioni possono aiutare a risolvere la situazione:

I seguenti pacchetti hanno dipendenze non soddisfatte:
 kwin-x11 : Dipende: kwin-common (= 4:5.24.5-0xneon+20.04+focal+release+build63) ma la versione 4:5.24.5-0xneon+20.04+focal+release+build60 sta per essere installata
E: Impossibile correggere i problemi, ci sono pacchetti danneggiati bloccati.

If i try to update with "sudo pkcon update" I get this:

Code: Select all

Errore irreversibile: The following packages have unmet dependencies:
  liblcms2-utils: Dipende: liblcms2-2 (>= 2.12~rc1) but 2.9-4 is to be installed
  kwin-common: Dipende: liblcms2-2 (>= 2.12~rc1) but 2.9-4 is to be installed

It is written in Italian, I hope you will still be able to understand it. Thank you for any help.

Thank you for the answers.

So Im not alone.

Wayland is not working for me either: when I select it at the login screen, after the login Im just taken back to the login screen

Ill try the other solution and report back

edit: aptitude install kwin-x11 did the trick for me. Various solutions were presented, as you said, I choose the 4h or 5th one kinda at random, cause it looked good (unfortuntely I didint take note of its details) and after a reboot everything was back to normal

I got bit by the same thing yesterday. Trying to install kwin_x11 didn't work for me... there were dependency issues. I had a backup of my system, so I thought I would try to "fix it"... but it just went deeper and deeper. Wound up restoring... It would have been nice if there was some sort of warning that they were making such a pivotal change. I assume I should hold off on applying updates for a while, while this gets sorted out... but how long?

This bug affected me to and i can't log into wayland session.

I tried again, I updated "aptitude" and now it works for me too. Thanks for your help!

Updates just solved the bug

Great to know! Thanks!

Thanks everyone for the help.

sudo apt install kwin-x11 fixed the problem for me.

Has anyone reported an official bug on bugs.kde.org ? I've looked for it, but couldn't find any trace. And it's important as the KDE developer team is pretty responsive to the official bugs whereas I'm under the impression that they rarely check this forum...

EDIT:
There is a bug already reported, I've finally found it:
