Thank you for taking the time to report this bug and helping to make
Ubuntu better. We are sorry that we do not always have the capacity to
review all reported bugs in a timely manner. I'm sorry that it took
almost five years for someone to acknowledge your comment.
Ubuntu 16.04 (xenial) reached end-of-standard-support on April 29, 2021.
As this bug report was never confirmed by another user and seems to have
been fixed by a change to the system hardware I'm closing this by
changing the status to 'Invalid'.
** Changed in: xorg (Ubuntu)
Status: New => Invalid

Title:
failure of xrandr to find any outputs
Status in xorg package in Ubuntu:
Invalid
Bug description:
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

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

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.
