System will not boot since changing display manager

[steveieo]

Hello all,

I was trying to switch my display manager from lightdm to ly, and I cannot successfully boot my system after performing these steps:

Sudo systemctl disable lightdm.service,

And then immediately,

sudo systemctl enable ly.service

(I think I skipped a necessary step in there?)

And when I reboot, I get an authentication error, without ever getting to the display manager login screen.

Has anyone some suggestions as to how I can rectify this?

Thanks for any and all kind suggestions.

Hello,

If you can open a TTY and log in to the system, you can check the status of the display manager :

systemctl status display-manager.service

Hello, and thanks for the reply.

I cannot get to the tty. System seems to hang.

Have booted from live-iso to use chroot, but cannot find out how to mount boot and home partitions as they are on an nvme. Been looking around.

sudo mount  /dev/nvme1n1p2  /mnt 
sudo mount  /dev/nvme1n1p1  /mnt/boot/efi
sudo arch-chroot /mnt

example
