Shutdown button for headless systems

[Jimmy T.]

Hi,

I was reading a few sections and someone was talking about shutting down the RPi sending SSH commands or using the web interface which is fine, but when your done for the night you don't want to have to connect just to power down properly.

So far just powering off has not caused any issues, but if it did one would not know until the next time it's powered on and that would be at the next show.

Could a command be added that we can add to a button on the virtual console that would cause the system to shutdown or the application to exit. You could put an optional 10 second delay and if another button is pressed it cancels it. Also a shutdown function like the start-up function would indicate it is shutting down.

I could add a final page on my console for this and assign to a button. That way I tap up pages 5 times and press it and it shuts down gracefully.

Thanks for the ear...

Jimmy

Shutdown button should be already added in git and 20150220 rpi image (guessing from git logs, I didn't check it myself. see https://github.com/mcallegari/qlcplus/c ... 4438bafada

If I understand correctly, he wants a shutdown button in the Virtual Console.
Now it's only in the web interface.

Not sure if I want to implement that. It's specific to the Raspberry Pi and so far the ext4 filesystem that Raspbian uses, shows no corruption when unplugging the power all of a sudden.

So far I have not had any corruption from killing the power either. I just seen the comment and thought it would be a good idea.

Corruption only happens when the system is writing and I think the RPi does it quickly enough that we don't get any corruption.

I'm fine with that.
