I didn’t use chroot in Manjaro. How do you do that? I did this:
I ran su -s to become root. I was not challenged for a password. Strange. I had discovered from this article that I would have to mount the hard drive in the Live USB environment in order to gain access:
Following those instructions, I ran (as root):
mount /dev/sda2 /mnt/recover
Using ls -a command, I was able to see that I had access to all directories and files on the hard drive. The sddm config file is at /usr/lib/sddm/sddm.conf.d/default.config I tried to open that with sudo gedit but gedit would not do that. I then copied the default.config file from my Backups directory to the location listed above. I shutdown the Live USB and booted into Archlabs. Problem remains - blank screen where the login screen should be.
What have I overlooked?
