Screen turns off during boot - Kernel 6.12.25?

Support Graphics & Display
1

This morning, I used my PC without issues. To my knowledge, I didn’t install, uninstall or update anything (I know everyone says that).

This afternoon, when I tried to boot my PC, it looks normal up to the point when the Manjaro boot screen is supposed to show (with the Manjaro lettering at the bottom and the three animated dots above it), but then the screens claim to have no input and turn off. No amount of waiting resulted into anything.

I tried pressing Ctrl+Alt+F2/F3 but without success, the screens stay off. After a while (I might have also pressed Ctrl+Alt+Del at some point), the PC rebooted.

I could boot a (very old) Manjaro live USB, so luckily it’s not a busted GPU.

I managed to chroot into my Manjaro installation and enable the grub menu, by which I found out I can boot into Kernel 6.1.135

So it might be Kernel 6.12.25, which I also have installed and would be the default (though I wonder why it worked this morning, or yesterday, or …).

How do I fix boot with kernel 6.12?

Thanks in advance!

Hi @WhySoComplicated,

This is a very bad ideaTM.
Manjaro is a curated rolling-release distribution that needs constant maintenance. It’s not a set-and-forget thing. If you’re unable or -willing to spend time updating and maintaining it, you’d be better off with a point-release system, like Ubuntu or Linux mint.

If you can boot into Kernel 6.1, as you said, it would not be difficult to reinstall 6.12. If you want to. This can be done as follows, from within a booted 6.1:

First, let’s see which kernels are installed. Please provide the output of:

mhwd --listinstalled

Thanks for your reply. We apparently have a communication problem.

My point was that I didn’t change system configuration between a working boot (this morning) and a non-working boot (this afternoon). System is up to date (stable branch).

Please provide the output of:

See above.

That wasn’t how I understood it, I apologize.

The rest of my answer still applies perfectly.

As per your suggestion, I reinstalled kernel 6.12 and today I could boot it without issue. Twice.

So I guess yesterday was just a disturbance in the black magic that powers computers?

Seems that way.
