failed to start light display manager blfs (system gets stuck)

After installing the required packages and enabling lightdm system gets stuck is there a way to run system again with no GUI to fix it

Thanks a lot

Hi is this systemd?

if so systemctl disable lightdm.

Then you can use startx, dont forget to create a /home/user/.xinitrc so you can start your desktop

Thanks a lot for reply
Yes it is a systemd but system unable to start and I no longer have access on the system

When grub boots edit the kernel line
root=/dev/sdX -s ro

add the "s" flag to kernel line, that will let you get root on the system

Thanks million of times
It is more than appreciated
