No booting to previous kernels (4.15.0-23 or -20) doesn't solve the problem, also removing 4.15.0-24 doesn't help here.
I'm in doubt it's a kernel problem.
If you do a little research you'll find that this issue (Started gnome display manager. dispatcher service ...... tem changes.pp link was shut down) also happened with previous Ubuntu versions. It seems related to GDM3.
I tried to disable wayland in GDM3 (by setting WaylandEnable=false in custom.conf) also of no help.
