I wish I could offer more info than this, both distros use Gnome, both fail at exactly the same moment in boot process.
Background changes, mouse icon is shown and then everything freezes.

Both distros work when running from live-usb. Problem asserts itself when booting from hdd. I've tried repartitioning.. I am using /boot/efi

Will try to repartition again, as it makes sense that could somehow be the issue.

EDIT (last few lines of boot.log):

EDIT: I found this answers which helped a lot. However in my case problem doesn't seem to be in the display manager, i've tried gdm gdx and lightdm and all have same issue.

It seems that the problem is likely with the GPU, I've purged nvidia drivers (no effect) and am reinstalling them ATM. If this doesn't work I will try to enforce usage of intel gpu (if that's possible)

I had same issue in RHEL 7.6 with gdm 3.28 after X authorization. I think this is gdm bug.

1. Open second console: Ctrl+Alt+F2



2. 
   

   Run htop, find X process and send SIGTERM to it.

   
   
   
   • 
     F4 type gdm - to find X process
   
   
   • 
     F9 => SIGTERM
     
   
   



3. X Window will autoreload and from the second try gdm will work properly.



4. 
   

   Optional: you may want to add these lines to /etc/gdm/custom.conf to avoid login screen:

   
   
   

   AutomaticLogin=username
   AutomaticLoginEnable=True
   

   
   

If somebody runs into the same problem:

I've logged in using ubuntu recovery mode, resumed to fully booted state. Using ubuntu additional drivers installed proprietary Nvidia drivers, now everything works!

I've also switched display manager to light-dm but this likely had no impact.
