Blank screen after boot


I am writing this because I'm facing an issue of blank screen after reboot.
The thing is I did try many of the troubleshooting from the forum but had no luck

This is my inxi -Faz output

Can I get any help please?


Do you try "black screen" by jonathon?

If nothing work, use last snapshot (timeshift/snapper).

I tried jonathan's post and few others.
If I try snap shot, won't the problem repeat if I reboot it again?


Oops, you need AMD.

I have exactly the same laptop model, but I was currently using the linux-lts kernel (which worked fine, so this is a back-up option for you: login from a live usb, chroot into your system and execute sudo pacman -S linux-lts linux-lts-headers).
I just managed to install successfully the 5.14.15-zen1-1-zen, so if you recover a snapshot and repeat the update you should not have any issue.
Alternatively, you could again login with the live USB, chroot and reinstall the zen kernel, probably something went wrong the first time.


Fine I'm in the live usb right now. I tried executing the command but it said package not found.
I'm sorry but can you tell me how to install the 5.14.15-zen1-1-zen kernel?

sudo pacman -S linux-zen linux-zen-headers

Be sure, you are up to date with -Syu


So you are trying to say there was a problem with my kernel.

I now seem to have ''5.14.5-zen1-1-zen" kernel.

I tried rebooting once and everything was fine.

I've got a question though

With the package installer prompt that comes right after you boot up for the first time, are you not supposed to install another kernel?

It is up to you. Many users prefer to have more than one kernel on their systems. Sometimes one may have better hardware support than another, or maybe some users just like wearing belts and suspenders. :wink:
