Public bug reported:
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_LINUX_DEFAULT="quiet acpi=off"
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!!!
