Power button action - shutdown

e-vallejo

Hello!

First of all, to all maintainers, THANK YOU! for maintaining this great OS, really.

Now on to business, I'm on Solus budgie and I've found that if the power button action is set to shutdown, it won't do anything, it used to show the shutdown prompt and with a second press, it actually did the shutdown. My guess is something kinda broke with a gnome update.

I've tested it with 2 different machines (desktop and laptop) with the same result. It's no big deal and i don't know if this is on purpose but i just wanted to let you know.

Same issue here. Thanks for reporting e-vallejo

I've experienced it, too, after the last update.
Yet, as it has happened before I couldn't be bothered to report it - it had gone away after some time so I hope it will eventually vanish this time, too.
(Mind you, there are three people who I've convinced SOLUS to be the best choice of OS for them so if they should ask why the heck their power button doesn't work the way it used to I would love to be able to give a valid reply!)
Devs, you're listening?

If you go to Settings > Power, what does it say for both "Power Button Action" and "Automatic Suspend" for you?

Can you also run this in the terminal and paste the output?

gsettings get org.gnome.settings-daemon.plugins.power 'power-button-action'

SOLUSfiddler

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

tomocafe

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.

SOLUSfiddler

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.

tomocafe

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".

SOLUSfiddler

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

SOLUSfiddler

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

tomocafe

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

SOLUSfiddler
In this order:

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

Then you should see some debug messages in the terminal.

SOLUSfiddler

tomocafe
I see, changing the settings WHILST the terminal is open!

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.

SOLUSfiddler

tomocafe
I entered dmesg | grep -i button.
Output:
[ 4.159768] input: Sleep Button as /devices/LNXSYSTM:00/LNXSYBUS:00/PNP0C0E:00/input/input3

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

tomocafe

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?

SOLUSfiddler

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!)

SOLUSfiddler

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?

tomocafe

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.

SOLUSfiddler

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.
