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.
