System is no longer booting properly after two recent snapshots (tumbleweed)

[vinylen]

Hi,

Ever since kernel 6.8.2-1 was released in a snapshot a few days back, i cannot boot my machine properly anymore. After booting my machine it does not show the KDE plasma login screen (is this SDDM?), instead, it gives me a tty where i can login with username and password.

I thought this might be resolved in the next snapshot of tumbleweed, but i ran zypper dup and got a new kernel (6.8.4 something i think?) and the issue is still the same.

When booting my machine i have to boot with the old 6.8.1-1 kernel, then everything works as expected.

I’ve been looking at journalctl -b -1 | grep sddm but i can only see this:

Apr 08 12:31:14 linux-pc sddm[1712]: Initializing...
Apr 08 12:31:14 linux-pc sddm[1712]: Starting...
Apr 08 12:31:14 linux-pc sddm[1712]: Logind interface found
Apr 08 12:31:32 linux-pc sddm[1712]: Signal received: SIGTERM
Apr 08 12:31:32 linux-pc display-manager[1701]: Starting service sddm

Please let me know if i can provide any more information to resolve this.

Thanks

Boot a “bad” kernel, save output of

journalctl -b --no-pager --full

and upload to the https://paste.opensuse.org/. Also collect the same output immediately after booting a “good” kernel.

Sure thing.

Good kernel boot - 6.8.1-1

Bad kernel boot - 6.8.4

Thanks.

You miss NVIDIA kernel driver for the new kernel. How did you install the driver?

Ah i see, i originally followed this but recently i started fiddling around with getting stable diffusion and CUDA to work together so i must have broken something then.

I will see if i can uninstall everything nvidia related and follow the directions on the wiki again. I’ll report back, thank you!

As @arvidjaar said, i was missing NVIDIA kernel driver. I followed the steps here to reinstall the nvidia drivers. It’s now working and i can boot into latest kernel.

Thanks!
