Tumbleweed - Kde Plasma 6 fails to start in Wayland, X works fine

@bandes: The OP can start KDE Plasma Wayland even from a VT (without any displaymanager involved).

Hi @deano_ferrari, definetely something went wrong in my system. I atache you the log of the command: ‘dbus-run-session startplasma-wayland > wayland.log 2>&1’

Sorry, I don’t know how to atach a file in the reply…

Best to start your own dedicated topic for this.

I seem to have fixed this… at least in part, I cant remember which fix it was because I tried a few hail mary’s. It seems to have have something to do with SDDM, I cant remember what steps, but its definitely not using sddm now, I think its using lightdm but not sure. The system came up to a black screen with a flashing cursor, I switched to another terminal and ran modprobe nvidia-drm, and it booted to a funky looking greeter from what Im used to. I was able to select plasma - wayland from the settings icon, and boom, it came up.

I’m so confused… so the NVIDIA driver is not loading automatically, like has been the case for some time. What seems to be happening to me is that plasma is expecting the nvidia driver to be loaded but its not?? not sure if this is even possible to be an issue. The system boots to a black screen with a flashing cursor in the top left. If I change TTY, ctrl alt F2, F3, nothing… if I select ctrl alt f4, it loads this login screen…

Gnome and Plasma X11 are the only options, if I switch TTYs again to F5, I can login and then run “sudo modprobe nvidia-drm” and plasma loads immediately and comes up in the Wayland session. Is there a way to get the nvidia kernel driver to load automatically again and maybe this issue is completely resolved at that point?

26

This really needs a user with NVIDIA hardware to chime in. I don’t know whether this is a case of the graphics hardware not being ready when the driver loads, or something else at play. Are the nvidia modules loaded early?
sudo lsinitrd | grep nvidia

FWIW, here’s an old NVIDIA thread discussing early KMS…

I’m not sure if it is relevant or helpful here. Hopefully, others can help with further diagnostic advice, next steps etc.

27

It is not plasma, it is display manager waiting for the available graphical seat. It has been discussed multiple times on these forums.

Please, post computer text as preformatted. Look at the previous post how it is done properly.

Anyway, as you see, NVIDIA modules are blacklisted and so are not loaded automatically. Check where it is done.

grep -ri nvidia /etc/modprobe.d /usr/lib/modprobe.d
31

I saw that too and was already looking for it, its not in modprobe.d, theres just an empty 50-yast.conf in there

I made a typo there. It is nvidia, not nividia. And posting screenshot is even worse than posting unformatted text.

33

THANK YOU! Im having issues logging out and rebooting but I can work on that, the system is now booting to Plasma in wayland automatically after commenting these out.

terracide@localhost:/usr/lib/modprobe.d> sudo nano 50-nvidia-default.conf
[sudo] password for root: 
terracide@localhost:/usr/lib/modprobe.d> grep -ri nvidia /etc/modprobe.d /usr/lib/modprobe.d
/usr/lib/modprobe.d/09-nvidia-modprobe-bbswitch-G04.conf:# blacklist nvidia
/usr/lib/modprobe.d/09-nvidia-modprobe-bbswitch-G04.conf:# blacklist nvidia-drm
/usr/lib/modprobe.d/09-nvidia-modprobe-bbswitch-G04.conf:# blacklist nvidia-modeset
/usr/lib/modprobe.d/09-nvidia-modprobe-bbswitch-G04.conf:options nvidia-drm modeset=1`
34

Why am not I surprised … just remove whatever package this file belongs to

rpm -qf /usr/lib/modprobe.d/09-nvidia-modprobe-bbswitch-G04.conf
35

Ok, that explains why the drivers weren’t loading. Did you explicitly install the bbswitch package recently?

36

No, that issue started after a system update, and it appears the package its related to is SUSE Prime. Maybe during the upgrade it noticed the embedded GPU on my Core I7 13700k and tried to setup bumblebee, not sure, I assume I can just remove prime via yast ?

37

The inxi graphics output you shared only showed one NVIDIA device present.

38

I mean I have an RTX 4080 discrete Nvidia GPU, and my cpu has an embedded intel gpu as well.

39

Yes, but it doesn’t turn up in the inxi output - so disabled.

40

its disabled automatically by bios if a discrete card exists, dunno, I removed Suse Prime, so far so good.
