Looks like I can reproduce the issue. I do have an X220 with a docking
station and external display. If I start the system with the lid closed,
the internal display is apparently not deactivated.

I remember that this worked in the past, and I suspect an issue related
to a kernel update:

> Kernel: Linux 4.9.0-3-amd64 (SMP w/4 CPU cores)

I could reproduce the problem with
linux-image-4.9.0-3-amd64  4.9.25-1

I then pulled 4.8.15-2 from
http://snapshot.debian.org/package/linux/4.8.15-2/

With that kernel, the internal display was correctly disabled when I
booted with the lid closed.

Can you confirm this observation? Does 4.8 work properly?

Regards,
Michael
