Many bugs are now accumulating with this and similar issues surrounding Xorg. This is just one example https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1764087 There are others. Some are related to Lenovo laptops but not all. Shame that 18.04 LTS has been allowed to be released without this inherent bug being fixed. It is damaging Ubuntu reputation.

When I reboot the screen will freeze (requires reboot) before the login prompt if I have both my digital display port and vga plugged in while my laptop is open. If I unplug the external monitors it boots fine. If I boot then quickly close the laptop screen it boots fine.
