Manjaro doesn't start after kernel update

[kalu_ucher]

Hi everyone,

After Manjaro update, system notified me that kernel 5.13 is not supported so I update it to 5.15. After this update I change it to 5.15 having flickering in my screen after screens goes dark or after ivernate. So I tried to install 15.10 amd remove 5.15. But I think I didn’t run no kernel or I don’t really know but Manjaro gets stucked flickering just after booting so I cannot start de OS to change the kernel.

How can I fix this please? I cannot see neither the manjaro boot options when escaping the boot on start.

Need help as I don’t have much knowledge

Thanks a lot

Update: Now I see manjaro boot options, I got within advance section Kernel 5.10.84-1-x64 and the same one but says - fallback initramfs. I got a recovery USB as well in case it helps

Also yesterday I deleted opencl-mesa and install intel runtime drivers as I couldn’t use davinci resolve. After did this everything worked well and davinci recogniced iris xe graphics gpu. So I cannot think this is due to this change but I don’t really know

I cannot enter to the OS to have more specs sorry…

Yeah now I can see… What can I do now to recover it? I have some important documents…

Sorry but I started to learn linux just one year ago and I didn’t now this. How can I fix it?

[ishaan2479]

if you are able to enter grub advanced options then you can get into manjaro with any available kernel. if not present then boot with a live usb:

sudo manjaro-chroot -a
pacman -Syyu
mhwd-kernel -i linux54 #install the 5.4 lts
mhwd-kernel -li #verify if correctly installed
exit #end-chroot

side note if you are not able to see grub on boot then:

sudo manjaro-chroot -a
vim /etc/default/grub
#change GRUB_TIMEOUT_STYLE from hidden to menu
update-grub #this is a command
exit

reboot

Switch from Windows:

[HowTo] become a Manjaro power user when you're a wizard at Windows but a N00b at Manjaro / Linux

Difficulty: ☆☆☆☆☆ Remember when you installed your very first Windows, added bells and whistles and then couldn’t see the wood for the trees any more and had to re-install? Well, you’re in the same situation now: You’re a N00b again! Embrace it! I know right now you’re thinking:

Why is this so much more difficult than Windows?

I am in Manjaro Advance Options, and I see three options:

• Manjaro Linux, which starts normaly so have the same issue
• Advance options for Manjaro Linux, there I got Kernel 5.10.84 and the same as fallback initramfs. None do the trick…
• UEFI Firmware settings

And above E = Edit Boot Options C = GRUB command line…

How to proceed there? So sorry for my ignorance

should have worked with 5.10

have you installed 5.10 in chroot env??

[kalu_ucher]

Sorry don’t know what’s that. I just installed it by Manjaro’s System Settings > Kernel. But did it wrongly installing 5.10 and removing 5.15 which was the one running at that point. So I reboot and now I cannot enter. I noticed that using recovery USB which has kernel 5.13 starts but withing the USB so I dont know if there, using the terminal I can do something with the kernel like you said or it just affects the USB’s Manjaro? I feel very stupid after done that…

we can enter a broken (or unbootable in your case) system from the live usb and fix it. here is guide:

[HowTo] Chroot from or into any Linux distribution

Difficulty: ★★★☆☆ Step 1: Mount your system. This works for both GRUB and EFI systems/installations Okay, the first thing to do is to be root. To do so, open a terminal and type in sudo -i then hit the Enter key. You may then give in your password if prompted. We then need to create a directory where we will mount the target system. In this case, let’s make a directory named “chroot”, by entering mkdir /chroot in the terminal. Time to find where is your system located!! To do so, you may e…

follow these steps and install linux5.4 lts from the internet through the usb to your system (kernel version of live iso on usb doesn’t matter)

Thank you, I am going to try that And will let you know…

[kalu_ucher]

After synchronize package databases, I do the command to install linux54 within chroot but after synchronizing it prompts “error: target not especified”.

Also I got this error message after “sudo manjaro-chroot -a”:
Grub-probe: error: cannot find a GRUB drive for /dev/sda1. Check your device.map.
Mounting (ManjaroLinux) [/dev/nvme0n1p2]
mount: [/mnt]
mount: [/mnt/boot/efi]

Don’t know if this is ok…

this is fine. no need to worry.

try now

sudo manjaro-chroot -a
pacman -Syyu
pacman -S linux54 linux54-headers linux54-extramodules
pacman -S $(pacman -Qsq "^linux" | grep "^linux[0-9]*[-rt]*$" | awk '{print $1"-headers"}' ORS=' ')
pacman -S $(pacman -Qsq "^linux" | grep "^linux[0-9]*[-rt]*$" | awk '{print $1"-extramodules"}' ORS=' ')
exit #end-chroot

[kalu_ucher]

Man you the boss now its working.

What should I do now? Stick with this kernel or just don’t removing a running one I can try wich one fits better to prevent image flickering after screen goes off? This kernel works well in this case

Have one question, when removing a kernel all its dependencies and extramodules go away as well?

The way to change the kernel is at booting like I’ve done or can I do it at System Settings GUI? In case I want to try differents…

Thank you a lot

Did you know that Manjaro has a very nice wiki? It would certainly be a good idea to take a look there. Among other things it contains a guide on how to manage kernels.
