Public bug reported:
I have a very new Lenovo X1 Yoga 2nd edition, with oled display.
The exact model is 20JECTO1WW.
The BIOS is N1NET27W. I am running a vanilla Ubuntu 16.04
lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 16.04.3 LTS
Release: 16.04
Codename: xenial
uname -a
Linux gjs-yoga 4.11.0-14-generic #20~16.04.1-Ubuntu SMP Wed Aug 9 09:06:22 UTC

Until recently things worked quite well. But on August 26 I got an update from
Ubuntu and
things began to decay.
In particular, I can no longer display except on the built-in display: For
example, xrandr
cannot find any outputs, even though this laptop has a (working) HDMI output
port.
xrandr --verbose

v: height 1440 start 0 end 0 total 1440 clock 93.00Hz
Notice there are no (even disconnected) outputs other than default.
Another symptom is that system restart always turns off the power rather
than rebooting.
I looked at the manifest of the update that seems to have caused trouble and
the only
suspicious entry is a microcode update from Intel.
Here is the entry from the apt history log:
Start-Date: 2017-08-26 17:54:05
Commandline: aptdaemon role='role-commit-packages' sender=':1.87'
Upgrade: intel-microcode:amd64 (3.20151106.1, 3.20170707.1~ubuntu16.04.0),
I hope that someone knows what is the problem here. I am stumped.
