No shutdown via LibCEC

Bug report

Describe the bug

I use a USB-cec adapter. When the TV is switched off I want the htpc (nuc8i3) to turn off as well. Therefore I configered "When the TV is switched off: Shutdown" in the Settings-System->Input->Peripherals-CEC adapter config.

However the htpc does not shutdown when I turn the TV off, but the Kodi application stops and the HTPC stays on (shows the ubuntu desktop). This is the same behaviour as when I choose "quit" in the "When the TV is switched off: " config of the CEC adapter.

When I choose "Power off system" from the "Power Options" menu it does shut down.
When I choose either hibernate or sleep from the "When the TV is switched off: " config it does actually hibernate or sleep.

I use Ubuntu 18.04 with Kodi 18 beta 5.
In Kodi 17.5 Libreelec it was working fine.

Expected Behavior

Here is a clear and concise description of what was expected to happen:
The pc should shutdown when I power off the TV as set in the configuration.

Actual Behavior

Kodi quits, but PC stays on.

Possible Fix

?

To Reproduce

Steps to reproduce the behavior:

1. Turn on Kodi
2. Turn off TV

Thanks for the report, I'll have a look into it.

I actually found the bug/a workaround. When I go to settings->system->power saving and set "shutdown function" to shutdown it actually works. So it seems the cec adapter settings "listen" to this setting instead of what is explicitly configured there.

[lrusak]

I'm not sure if there is much we can do about that or if it would be ok to override the shutdown function setting.

[mrblond18]

I understand, but the way the CEC adapter settings are presented now are misleading. It suggest you can choose between quit and shutdown there, when in reality it depends on another setting.

Could this issue be related to:
#10512
AND

@lrusak I guess you'd have to rewire the shutdown logic such that it actually uses the CEC configuration value when receiving the CEC event.

I ran into the same issue. I believe just rephrasing the related item in the CEC adapter config, e.g.
When TV is switched of: Shutdown (as configured in Power Savings)
would go a long way to mediate this issue.

Hi everybody,

Tested on nexus 20.2 on windows and 20.3 on librelec(linux based) and the issue stills the same.

But I found a workaround... On the menu port saving, add a timer for shutting down at 5 minutes on the function "shutdown function timer "

And then power the TV.
The first time, you'll need to wait the timer of 5 minutes and the Kofi will shutdown ( quite normal)
Then next shutting down, without modifying anything, will occur immediately after power of the TV.🙄
It's strange but I'll stay with that 😜
