Bug Description
Upgrade from 16. (LTS) to UBUNTU 18.04 successful until restart now - then failed to boot up. acpi=off allows me to boot up. The 5 blobs on the splash screen were then permanent so switched off as:
sudo nano /etc/default/grub
GRUB_CMDLINE_
CTRL X, Y, Enter
sudo update-grub
I still have a problem that my SAMSUNG monitor is "unknown" and I don't know how to overcome this. It is now in a very strange aspect ratio.
Not expecting these types of problems on an upgrade!!! It took hours of effort to work out how to get the computer to start up before I could edit the above file. I would have been completely stuck without access to an old Windows machine!!!

1. Samsung monitor problem overcome by Software & Updates -> additional drivers tab -> check NVIDIA driver instead of open source driver.
2. NVIDIA driver also corrects the permanent blobs problem noted above so "quiet splash" can be put back into the grub file.
3. Note also "acpi=off" stops the computer powering off when shutting down (manually use the front panel button when all activity has stopped) but this is a small price to pay for allowing the computer to boot up!
