  • I will very likely migrate to BTRFS on my next install. I'm reading Snapora's repo now, looks like an awesome tool. Thanks for the tip!

  • I did check it, yes, but the page doesn't appear to be relevant or contain much information. Another comment above (or below) mentioned that KDE Plasma can't run without a compositor.

  • You are right, I should have made this clear. I am not on Nvidia, I am using an old Thinkpad on Intel Haswell.

    I'm glad to know my problem isn't completely new. I'll look into it further online. If you ever find a link to a report of a similar issue, I would be happy to see!

    Edit: I found this link, the issue reported appears to be very similar to what I'm seeing here https://libreddit.tux.pizza/r/kde/comments/jhqbnz/kde_plasma_rendering_problem_black_squares/

    Edit 2: I finally solved my problem! It was indeed an old problem already reported somewhere.

  • You are absolutely right. I just tried apt purge kde* plasma* libkf* and apt install kde-full followed by a reboot. But sadly, the problem persists.

  • I agree with that. I suspect you might be right. SDDM (Breeze) is also weird with transparency. However, I just installed materia-kde but unfortunately the problem persisted (screenshot attached). Before that, I ran apt purge kde* plasma* libkf* and apt install kde-full. That too didn't solve my problem.

  • Tasksel seems to be correctly set,

     
        
    ~$ tasksel --list-tasks
    i desktop       Debian desktop environment
    u gnome-desktop GNOME
    u xfce-desktop  Xfce
    u gnome-flashback-desktop       GNOME Flashback
    i kde-desktop   KDE Plasma
    u cinnamon-desktop      Cinnamon
    u mate-desktop  MATE
    u lxde-desktop  LXDE
    u lxqt-desktop  LXQt
    u web-server    web server
    u ssh-server    SSH server
    i laptop        laptop
    
      

    I tried apt reinstall kde-full, but unfortunately nothing changed.

  • I audibly laughed at this. I actually knew I was entering treacherous waters by running apt full-upgrade in Sid, but still thought "well, we'll see..."

  • Thanks! Some packages were installed, but it didn't solve it yet (even after a reboot).

  • If I am not mistaken, I used a Debian KDE live image from the official repository then switched the mirrors from Bookworm to Sid. The system went months without a single issue, then this happen.

    Your suggestion will actually be my solution of choice if everything else fails: reinstall / and import relevant files from a backup that I already have.

  • Thanks for the tip! However, I tried apt reinstall kde-full and apt --fix-broken install, but no packages were installed and (unsurprisingly) the problem still persists.

  • The Gentoo sub had such a nice subtitle because it is indeed accurate! Definitely one of the things I like the most about "flexible" distros.

    "Gentoo Linux: Because you like it when the power is in your hands"

  • Thanks for the recommendation! I will definitely do it when I eventually install some other distro in the future.

  • I do store regular backups of this machine, but not of /var. I can always reinstall Debian (or whatever other distro), while keeping other relevant configs intact (stored in the backups) and not lose any critical data.

    I commented below that I did check /var/log/dpkg.log, but it didn't help much due to the high number of packages removed that day.

    At this point I am more curious to learn more about KDE and what is causing the problem, since other desktop environments (I installed mate) seem to work fine.

  • Sadly I am not using BTRFS for my root directory on this specific system. If I end up deciding to reinstall, I will definitely go back to BTRFS to avoid such problems.

    Debian actually has a KDE group named kde-full. I reinstalled it but the issue persists, which was honestly surprising to me.

     
        
    ~$ sudo apt install kde-full
    Reading package lists... Done
    Building dependency tree... Done
    Reading state information... Done
    kde-full is already the newest version (5:147).
    0 upgraded, 0 newly installed, 0 to remove and 87 not upgraded.
    
      

    The new user idea was really clever, thanks for the suggestion! I will try that now and see.

    Edit: the new user also presents the same problem. Actually, it makes sense, since SDDM is affected as well (I should have mentioned that before).
