Booting to black screen after latest update. Seems to be due to [FAILED] Failed to start Light Display Manager

2 days ago I updated via pamac GUI, suspended to RAM and when starting the system it gets stuck on a black screen. No amount of reboots managed to change this. Removing the quiet option of grub reveals [FAILED] Failed to start Light Display Manager

I know there are a lot of similar threads and I spent a couple of hours yesterday trying to fix it, but with no success. I’ll provide all the things I tried and I’m hoping someone can help me, because I’m out of ideas.

I can access tty via Ctrl + Alt + F2 as well as chrooting from live USB.

Things I tried (with no success):

  1. Switching to a different kernel. Tried with 5.10, 5.15 and 5.17.
  2. Adding MODULE=(amdgpu) to /etc/mkinitcpio.conf, running sudo mkinitcpio -p linux515 and rebooting.
  3. Reinstalling lightdm and lightdm-gtk-greeter via pacman -S lightdm lightdm-gtk-greeter.
  4. Changing this in etc/lightdm/lightdm.conf:
[LightDM]
logind-check-graphical=true
  1. Runnign sudo pacman-mirrors -f 5 && sudo pacman -Syyu

Any help will be greatly appreciated and thanks in advance!

so reruning update didnt gave you any errors?
output from:
mhwd-kernel -li

If you mean rerunning pacman -Syu - it says there is nothing to update.

5.15.49-1-MANJARO (linux515)
The following kernels are installed in your system:
   * linux510
   * linux 515
   * linux517

uninstall the 517, its EOL:
mhwd-kernel -r linux517
then reinstall video drivers:
uninstall:
sudo mhwd -r pci video-linux
install:
sudo mhwd -i pci video-linux
reinstall xorg:
pacman -S xorg-server
post output from:
find /etc/X11/ -name "*.conf"

Did all the steps above and rebooted with no success. lightdm.service status is still failed.

Output of find /etc/X11/ -name "*.conf":

/etc/X11/xorg.conf.d/00-keyboard.conf

reinstall also these, since they are mentioned in the xorg log:
pacman -S mesa glibc
reboot and see if it helped

Yes it worked! Thanks a lot.

Any idea why they might have caused a problem? I had no problems so far and I just did a pamac update.

after every update you need to reboot, not putting your pc to sleep…
