Are you using a commercial display driver  eg Nvidia  or Radeon, if so 
edit the grub line  GRUB_CMDLINE_LINUX_DEFAULT=  and  add no acpi to the 
end of that line. taking out the 'quiet' so you can see the boot process 
and where it might be hanging up.

See if it will boot then and if it doesn't boot to the desktop and your 
your still looking at a black screen  then do a ctrl  F1 and at the 
terminal type sudo purge Nvidiia*.*  or the Radeon equivalent.

see if that helps.  It will knock out the commercial graphics drivers 
and let Wayland take over.   I always remove quiet splash from the grub 
CMDLINE as I prefer to see any issues as the machine boots.


Good luck
