New install. I know my password. How do I recover my User name to access system?

Installed Manjaro. Blindly following bad advice caused boot crash.

Lesson learned!

I have loaded my personal files overnight, and reluctant to start over.
Because the system was just a day old, I forgot the user name.

But I do still have the password!

What's the command to reveal the user name from 'outside'. So I can boot into my setup and start repairing boot, as the instructions here suggest.
Thank you.

Check the contents of your /home. It contains your home directory, which is named after your username.

Just log in as root using the admin password you set at install time and to keep it simple for you..... Look inside the /home folder and you’ll see folders there for your users.

If you can not even log in because you cannot remember your username, there is still a way to recover your data. Note that this guide assumes you're the only user on the system.

  1. Boot the system into Recovery Mode through GRUB.
  2. Select [C] Grub Commandline.
  3. Type in this command into the terminal window that opens:
awk -F: '$3 == 1000' /etc/passwd
  1. Your username will be at the very beginning of the line on one of the returned lines. Typically there will only be one, but there may be more depending on your system.
  2. Reboot into normal mode and use the username specified.

If you are not the only user, replace the code on step 3. Look for a user with an ID greater than or equal to 1000 by:

awk -F: '$3 >= 1000' /etc/passwd

One of them is bound to be you. Or ask another user on the machine to pull the account list.

Thanks, but I have no idea how to do that.
I keep getting a blackscreen.

I get a screen that I believe is the bios entry. It has:
Manjaro Linux
Advanced options for Manjaro Linux
Any key press from there leads to a blank screen.
I can access grub command line, but I don't know how to proceed from there.

Or you can use the Manjaro USB stick to access the /home/ directory.

These dead ends I describe are when I'm using the Usb.The mac is dead without it.
Update, I managed to boot the Mac.

I'm inside 'my' system in the terminal, but can't find my home folders in the GUI. I'm only seeing the USB version of Manjaro files on the desktop.

What's the command in chroot to remove unwanted packages, thanks. (Bumblebee!!!)

Also, What does this mean, please? "Warning: No installed USB configs!"

I'm brand new to Manjaro, but have a little Terminal experience. Here's my system setup:

[manjaro /]# mhwd -li

Installed PCI configs:

In your filemanager, write to your addressbar:

/mnt/home

This is where your home folder is if you have chrooted in the terminal. If you have not, you need to mount your partitions first and go to whatever directory you mounted them to.

pacman -R package_name

However, with Bumblebee, you might want to use mhwd instead. Installing video-linux with mhwd should probably remove Bumblebee unless I'm mistaken.

You can safely ignore it
