Updates I did today Oct 21 2024 broke system

Help

I thought I had a properly working 24.04 Neon 6.2 system, but today’s update broke something.
When I do normal bootup, I get to the KDE Neon “spinning gear”, but only for a couple seconds before I get a black screen (and the keyboard numlock stops working)
Using the “recovery mode” boot I get to the repair options, but selecting ‘continue boot’ results in a black screen with a blinking underline in the upper left. And it just stays that way. But it hasn’t completely crashed, as I can press the power button and it will enter the restart process.

Booting kernel 6.8.0-45 works fine, so its’ something to do with the -47 kernel. Maybe Nvidia drivers? But they’ve been working perfectly for a long time now…

How do I even begin to troubleshoot this? There are no error messages, so I’m at a loss how to diagnose.

Any help appreciated!

And this is why I got rid of Nvidia out of my entire household around 4 years ago. Now, we only use AMD and Intel graphics. We all use KDE Neon.

Anyway, reinstall your drivers. I had to do this lots whenever I did a kernel upgrade. It was a pain. Which is why I am glad I got rid of anything Nvidia.
