Power button action - shutdown

tomocafe
It says:
AUTOMATIC SUSPEND: Off
POWER BUTTON ACTION: Turn off/Shutdown (OS is in German: Ausschalten)
The command gives me this: 'interactive'

I usually have mine set to Suspend, but I tried setting it to Power Off and it works as you described, bringing up the shutdown confirmation dialog.

FWIW, when I dumped the gsettings, I got interactive.

tomocafe
Yes, it's the settings for the interactive dialogue that I want to get. I didn't change anything for months before the last update, it used to work, so the settings should still work I guess.

Can you run Settings with verbose messages in the terminal and paste the output?

gnome-control-center -v

Set "Power Button Action" to "Suspend" and then back to "Power Off".

tomocafe
My output of the last command:
(process:3041): Gtk-CRITICAL **: 22:40:37.841: gtk_style_context_add_provider_for_screen: assertion 'GDK_IS_SCREEN (screen)' failed

tomocafe
When should I "Set "Power Button Action" to "Suspend" and then back to "Power Off"."?
Haven't done that yet.

SOLUSfiddler
That message is normal. You should see more messages than that. Did you use the -v flag?

SOLUSfiddler
In this order:

1. In terminal, launch settings in verbose mode: gnome-control-center -v
2. Set Power Button Action to Suspend
3. Set Power Button Action to Power Off
4. Close Settings

Then you should see some debug messages in the terminal.

Some other tests to run:

dmesg | grep -i button

In your terminal, give the command xev. Don't move the mouse / press any keys. Then press your power button as you watch the terminal. Did anything change when you pressed the power button? If not, the system is not reading your power button press.

tomocafe
I entered dmesg | grep -i button.
Output:

The I entered xev, but it wasn't accepted:
bash: xev: Kommando nicht gefunden.
(Means "command not found")

SOLUSfiddler You can get it with sudo eopkg it xev. But I see you are using ThinkPad. I remember that it takes a full second of pushing the power button for it to send the event signal. Silly question, but are you pushing the button long enough?

tomocafe
Will try the new command in a second.
Do I have to push the power button for as long as it would take to give me the shutdown confirmation dialogue?
Is that what you mean?
(I'm using a Thinkpad W530, yes!)

tomocafe
I downloaded and installed xev, then pressed the power button whilst watching the open terminal.
I kept the button pressed (nothing happened in the terminal) until the system was powered off.
What now?

SOLUSfiddler Err, sorry. Maybe you held it a bit too long. Try a quick push. If nothing shows up in the terminal, try for 1 second, but not too much longer. If you hold it down it probably does a force shutdown.

tomocafe
OK, I ran xev, this is the output of then pressing the power button for about one second:

elcobi How about dmesg | grep -i button? Thanks for helping to debug.

SOLUSfiddler So it is receiving something when you press the power button. But what I'm wondering is if what it's receiving is not a power button event, but a sleep button event, which GNOME might not be using as a trigger to launch the "Power Button Action".

When I give dmesg | grep -i button, I have two power "buttons": PWRB and PWRF. If I understand correctly, PWRB is a normal power button press. When I short press it, this is the button that gets received and then GNOME is showing the shutdown dialog as desired. PWRF is for Force shutdown (?) when you hold down the power button.

Can anyone else confirm this? Also, if this was working for you before, I wonder if something in the kernel or ACPI domain changed causing this.
