I get a Black screen at boot

If it’s installed, it’s installed. You don’t need to start anything.

However, I would now suggest a chroot environment, from where you can re-sync everything. So, enter a chroot environment:

How to chroot

  1. Ensure you’ve got a relatively new ISO or at least one with a still supported LTS kernel.

  2. Write/copy/dd the ISO to a USB thumb drive.

  3. When done, boot with the above mentioned USB thumb drive into the live environment.

  4. Once booted, open a terminal and enter the following command to enter the chroot encironment:

manjaro-chroot -a
  1. If you have more than one Linux installation, select the correct one to use from the list provided.

When done, you should now be in the chroot environment.

But, be careful, as you’re now in an actual root environment on your computer, so any changes you make will persist after a restart.

From there, rum a complete update to re-sync everything:

pamac upgrade && pamac upgrade --aur --devel || echo -e '\033[0;91mThere was an error upgrading the system. AUR packages not upgraded.\e[0m'

This will update your system and ONLY if that was successful update any AUR packages.

a Reminder: While use of the AUR is possible, it’s neither recommended nor supported.

I recommend pamac instead of pacman, especially for newcomers as pamac was developed by Manajaro (developers) for Manjaro and just takes care of more thing than pacman. For example:

Reboot and test. If it works, awesome! If it doesn’t, re-enter the chroot environment, and please provide the output of:

mhwd-kernel --list

and

mhwd-kernel --listinstalled

And:

awk -F\'\'' '\''/menuentry / {print $2}'\'' /boot/grub/grub.cfg

Because it seems it’s wonky and needs help to become less wonky.
