Just to confirm it has to do with LightDM:

When you messed up your system by keeping an unsupported (for months) kernel, you probably also broke your Nvidia drivers, that’s my guess. So once again, make sure to be up to date with pacman -Syyu, then use Manjaro tools to install latest LTS kernel 5.15, reboot, remove kernel 5.13, and remove/reinstall Nvidia drivers (check the WIKI for all that if you don’t know how to use Manjaro tools for that).

//EDIT: you edited your message above and added relevant log, that is what I guessed:

[    10.086] (EE) Failed to load module "nvidia" (module does not exist, 0)
10

yes, but I already tried all you suggested

11

You’re doing it wrong then.

You said you installed kernel 5.15 and removed 5.13, but you still use kernel 5.13, from your own messages, so what do we do with that?

12

I have followed these steps

13

Well I used this command which to my knowlege should remove the kernel I am using right now which would be the 5.13

but as I said
mhwd-kernel -li
Outputs:
Currently running: 5.13.19-2-MANJARO (linux513)
The following kernels are installed in your system:

  • linux515

thats just that

14

Go to TTY from your computer with CTRL+ALT+F3, login in this terminal, and do the steps explained here After kernel update 5.13 -> 5.15 system wont boot - #5 by Yochanan

sudo pacman -Syyu
sudo mhwd-kernel -i linux515

…reboot… then remove 5.13.

sudo mhwd-kernel -r linux513

Then when you are sure you have booted on kernel 5.15 and removed 5.13, reinstall Nvidia

sudo mhwd -r pci video-nvidia
sudo mhwd -i pci video-nvidia

Make sure to read your screen for any error in all the steps, if you have errors then obviously something will not go well so make sure everything is going properly. In case of error at any step don’t continue, report here the error. so we can figure it out.

15

Does it have to be through the TTY? The problem is that I cant get into it. That is why I always chrooted.
I have tried all the key combinations I could find online.

16

OK then if you can’t access TTY at all, then chroot your system but make sure you’re doing it right and no error message pops up. Also when chrooted you don’t need to use sudo for the commands as you will be in a root terminal.

17

Could mount -o bind /run/ /mnt/run/ cause any problems during the package updates?
I couldnt update before. I think its because /etc/resolv.conf is empty and I cant edit it, so I found this solution, but I am not sure if its alright to use it.

also mhwd-kernel -i linux515 gives me:

error: no targets specified (use -h for help)

and I am not sure I can do anything with that

18

To chroot you only need to do manjaro-chroot -a in terminal from the live environment, and select the system. Then you can use the commands when you are in the root terminal with system chrooted. I don’t know what you have done, I would reboot on clean live environment and start over.

19

I followed this
its basically the same but I have to mount the encrypted partition before chrooting

20

Follow what I wrote.

21

you cant just manjaro-chroot -a into encrypted system

22

OK then I can’t help.

23

As i pointed earlier, i thinking the information of the currently running kernel is misleading.
I’d go with chrooting as you managed to so far, and just reinstall the driver.

sudo mhwd -r pci video-nvidia
sudo mhwd -i pci video-nvidia
24

I already tried that. It was searching for the 5.13 drivers and couldnt find them if I remember correctly, so I installed video-linux instead which still didnt help.
Anyway I gave up and reinstalled the system, because I needed the laptop for school.

25

It was searching for the driver because you didn’t remove the unsupported, inexistent, kernel 5.13.
It couldn’t find them (and why you broke your system) because the drivers for this unsupported, inexistent kernel, don’t exist anymore in Manjaro repositories.

Now on your fresh system make sure you use a LTS kernel (kernel 5.15 for instance), and if you don’t, make sure you follow the announcement threads to keep informed of End Of Life of non LTS kernel and remove them before they are removed from Manjaro.

26

well if I correctly understand this thread mhwd tries to install the drivers of the current running kernel and the host kernel is seen as the current running kernel when chrooted. So this probably wouldnt work regardless, because the live system I was on was still 5.13
