Hello I also had a problem with both primary and second monitor with update to 4.4.0-43-generic Ubuntu 16.04.1 Xenial LTS.
Recovery mode also had - - - instead of letters.
Bug was solved by login in upstart 4.4.0-42-generic.
And weird, he had before installed linux-headers and all for the 4.4.0-43-generic, and after 3 restarts he installed without me deleting neither touching anything again linux-headers and all for the 4.4.0-43-generic as if it was not installed.
Maybe first install did not told the computer it was already installed ?
He still wants to update more things, like: linux-headers-generic linux-image-generic.
I think problem is all those updates should have been done at once, and it is in more then 4 parts. As if it was a big upgrade. So first it had put the link to the name, then the programs must be installed in more then 4 times by login the 4.4.0-42-generic upstart mode.
