After upgrading my system to linux-image-4.15.0-24-generic, I experienced
this issue where boot hangs at either started dispatcher daemon for
systemd-networkd.ce or Started Gnome Display Manager.... This is how I
solved it:

I booted up my laptop, went to recovery options and selected kernel
linux-image-4.15.0-23-generic. Upon bootup, I did Ctrl+Alt+F2 (if the tty2
freezes, do Ctrl+Alt+F1 and back again to Ctrl+Alt+F2), dropped me to tty2,
where I:

    Purged the kernel
    purged gdm3
    Reinstalled gdm3 & ubuntu-desktop

See below:

sudo apt purge linux-image-4.15.0-24-generic linux-headers-4.15.0-24*
sudo apt-get purge gdm3
sudo apt-get install gdm3 ubuntu-desktop
reboot
