<pre>Since Linux-image-4.13, as soon as the laptop screen is closed on my inspiron
1545 with Debian Stretch, my VGA monitor start to display an infinite amount of
(white?) horizontale line. So much that it hide everything and the display is
unusuable. The bug happen as soon as Systemd is starting services. If i open my
laptop screen again everything become normal. Same thing on the Gnome desktop.
Kernel from 4.9 to 4.12 work correctly, 4.13, 4.14, 4,15 and 4.15 + drm-next
have the bug.
Closing my laptop screen with Xrander or gnome-control-center produce the same
bug on my VGA monitor too.I tried to pass numerous kernel parameter found on
the web but no one worked.
I can submit a picture if it helps.
