[KDE] Boots to black screen after updating to kernel-6.18.6-200

I’m not sure how to report a bug because it is too vague, but after I updated to kernel-6.18.6-200 (still Plasma 6.5.5) I get a black screen with a mouse.

The hot corner showing the overview makes the rectangle animation with the blank desktop appear, but nothing else works.

my device is:
KDE Plasma Version: 6.5.5
KDE Frameworks Version: 6.22.0
Qt Version: 6.10.1
Kernel Version: 6.18.5-200.fc43.x86_64 (64-bit)
Processors: 16 × AMD Ryzen 7 260 w/ Radeon 780M Graphics
Graphics Processor 1: NVIDIA GeForce RTX 5060 Laptop GPU
Graphics Processor 2: AMD Radeon 780M Graphics
Manufacturer: LENOVO
Product Name: 83M0
System Version: Legion 5 15AHP10

Replicate the issue.

Shutdown if you can (switch to a secondary TTY using Ctrl+Alt+F3 if necessary).

Reboot using the previous kernel.

Post the output from journalctl --no-hostname -b -1 as text using the </> button in this text entry box.

Thanks here’s what I got: https://paste.grin.hu/Vfsu2Ts2/+inline

Which graphics device are you expecting to be used on this machine - the Nvidia device or the AMD device?

If it’s the nvidia device, can you post the output of inxi -Fzxx so we can see what driver is being loaded and perhaps try booting with the AMD card disabled in the BIOS.

If it’s the AMD device you expect to be being used, then I’ll let the amdgpu users chime in as I have zero experience with them and wouldn’t know what it was supposed to look like in a working system.

Updated, now I don’t see a cursor and can’t get into a terminal either. I forgot to add that, it’s a laptop so the integrated amd gpu always needs to work, the nvidia only sometimes.

Updated to kernel 6.18.7? You don’t state what you updated but I guess that’s what you mean.

Yes, I wasn’t sure because I just ran it from Discover.

It’s also happening on 6.18.7

Your journal output has:

jan 28 20:14:22 systemd-vconsole-setup[327]: setfont: ERROR kdfontop.c:212 put_font_kdfontop: Unable to load such font with such kernel version

It is often helpful to filter the journal output using the “priority” option. You might try removing the vga=791 from the kernel command line.

Hello,

I am pretty new to this as well, but sadly I am suffering from the same/similar error. After being on a work trip for a week, I updated my PC through discovery but sadly had the same errors as described.

After reinstalling pretty much everything in connection with nvidia I had a normal screen again, but no more “system logging in sound” and I had periodic crashes.

Any ideas how I could look this up?

This journal shows (with line numbers):

Can you reboot with this kernel now that the nvidia kernel module
(RPM: kmod-nvidia-6.18.6-200.fc43.x86_64) has been built?

I did an offline update and now after that Plasma’s fine.

Thanks for the tips.
