The same way as you did the vendor change to packman:
sudo zypper dist-upgrade --from <OSS-repo-alias-here> --allow-vendor-change --allow-downgrade
Replace < OSS-repo-alias-here > with your actual alias of the OSS repo on your system.
Or the way as described here or here.
Or like this - it also works, but this does not apply to my setting
Thank you! I am puzzled by the fact that llvmpipe is your CPU rendering “graphics driver” instead of AMD. This is strange. Just to be sure “kernel-firmware-amd” is installed.
Yes, I have just checked again to be sure. Is installed (main repository)
I haven’t changed anything else in the system… was running the last few months.
I have made many changes to my system and the behavior was the same as on your system, I think it is safe to say this is OpenSUSE’s fault (but that’s just my opinion so take it with a grain of salt)
@40476 As pointed out in your other thread, your issues on your box are due to Packman. Packman is not under control of openSUSE. Before trying to blame openSUSE, you should try to understand the basics of third party repositories.
But it seems you hijacked this thread with your issues as Lacerte has no packages from Packman.
With today’s update you mean TW20241122, so the last working one was TW20241121?
If lacerte has no packages from Packman and we are both having the same issue, who is providing those packages?
Lacerta’s terminal output tells that xwaylandvideobr dumps core.
Yes, I pulled the upgrade using zypper dup today. So it should be TW20241122. However, I only run zypper dup every 14 days
I see the, there are a few changes regarding systemd. Could this be a hint? but I have no idea about it
Since you update every 14 days it is very difficult to pin down the culprit. Since I am not aware of any related bug report, you should open a new one at https://bugzilla.opensuse.org/.
literally no clue what changed but rolling back and and running the update again fixed my problem, no clue why.
That’s weird, isn’t it?
I’m not doing a rollback for now. Try a bug report. Thanks for your hints and help 
For the sake of completeness: 1233694 – After upgrade (Tumbleweed), I can no longer log in via the wayland session, x11 is working
I rolled back and then tried update again, but same problem. Wayland no worky, X11 OK/fine.
