Comment 6 for bug 1764794

Testing this required updating several packages from xenial-proposed

In order to install them all I ran this:

sudo apt install -t=xenial-proposed linux-signed-generic linux-generic

(which is something that is not told in the previous document)

In its execution an error occurred; here is an extraction of the part of the output:

/etc/kernel/header_postinst.d/dkms:
Error! Bad return status for module build on kernel: 4.4.0-143-generic (x86_64)

If I would use open source driver nouveu, instead, I could test this, but I would not be able to use HDMI IIRC. Well, I'll try.
