[Bug 1801747] Re: External display not recognized, internal one goes to black

More infos. I installed the notebook from scratch with a 16.04.2 image
and update to latest 16.04 packages which installed 4.15.0-38 kernel.
The laptop has the correct behavior, without entering settings I can
switch/duplicate displays with the fn key.

So original problem seems not related to kernel version.

Bug description:
Hi,

I have 10 notebooks HP 1410s on which I replace XP/Vista with Ubuntu
18.04.1 I face a problem on ALL of them, as soon as I connect an
external screen, doesn't matter VGA or HDMI, the internal screen goes
black, only mouse icon is their, blinking from time to time but
reacting. External screen does show nothing but there is no "no
signal" info what means that source is recognized.

As soon as I release the video cable from external display, the
internal one come back to live after few seconds. The BIOS was updated
to latest available.
