System does not auto detect disconnection of external monitor

[Chih-Hsyuan Ho]

[Impact]
System does not auto detect disconnection of external monitor

Steps to reproduce:
1. install dell-bto-bionic-beaver-lancel-X84-20190507-42.iso and boot into OS
2. open "system settings > display settings"
3. connect laptop to an external HDMI monitor via HDMI port & cable
4. unplug the HDMI cable
5. check if "display settings" automatically detects the removal of the external monitor

Expected result:
display settings should automatically detect the removal of external monitor when unplugging the HDMI cable

Actual result:
System does not automatically detect the removal of the external monitor when HDMI cable is removed.
Sound setting also list HDMI audio in output tab after removal external monitor.

Failure rate:
2/10 to 1/10

[Fix]
two commits from upstream drm-intel-next-queued branch

[Test case]
see "steps to reproduce"

[Regression potential]
still possible, but for the distro only Eoan will get it. OEM kernels will get tested on systems that get it.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1835001

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[Timo Aaltonen (tjaalton)]

this is an old bug, and there have been several attempts to fix it in the past, but this series finally seems to make it upstream:

let's fix it in eoan at least, besides oem/osp1

Dear sir/madam,

I'm running Lubuntu 19.04 (64-bit) on a Dell Precision 7510 (with a Nvidia Quadro M2000M GPU).

The Quadro M2000M is governed by:
nvidia-driver-418 418.56-0ubuntu1
nvidia-prime 0.8.10

I've just upgraded to Kernel ver.:
linux-oem-osp1 5.0.0.1015.16

Since upgrading to kernel ver. 5.0.0.1015.16, the Quadro M2000M will not power down, e.g. Powertop shows 100% power usage for the M2000M, even though the "Intel" profile is selected via Nvidia-Prime.

When booting from kernel 5.0.0-1013.14, the Nvidia-GPU will power down just fine.

I'm guessing this problem was introduced by this changeset. I do not know if this problem warrants a new / seperate bug, if so i'm happy to create a new bug.
