Hi everyone, I ran apt full-upgrade last month and accidentally deleted a couple packages that weren’t supposed to be removed, due to me not paying enough attention. I could recover most of the system just fine, since most of the missing features and related packages were obvious to me. However, I still couldn’t figure out why transparency is not working on KDE, both in Wayland and X. I suspected it could be a missing compositor, but libwayland and libqt6waylandcompositor6 (and related packages) are all installed (and that wouldn’t explain why it isn’t also working on X).

I have attached a screenshot to illustrate what I mean.

I would appreciate if anyone could help me figure out what package might be missing that is causing this issue. Thanks in advance!

    Are you on BTRFS? If so maybe you could restore to a snapshot prior to the apt upgrade?

    I’m not very familiar with Debian, but perhaps there are official “groups” of packages that comprise a set of softwares, like KDE. Perhaps you could re-install that group, if it exists?

    You could also create a new user, log in as that user, and see if the issue persists. If so then you’ll know it’s a system wide issue. If not, then maybe you could migrate to the new user?

    Good luck!

      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

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).

        Debian doesn’t have package groups in that sense. kde-full is just a package which depends on the other KDE packages.
        So, if you tell it to install kde-full, it’ll just check that, yes, it does have the kde-full package installed, whether all the dependencies are fulfilled or not.

        You can try doing apt --fix-broken install (without specifying a package), maybe that will pull in the missing dependency.
        Or you can reinstall: apt reinstall kde-full

        you installed it without uninstalling first? have you tried an apt purge to get rid of related conf files, then reinstall kde?
