Power button action - shutdown

tomocafe · Apr 9, 2020

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

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.

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.

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?

SOLUSfiddler · Apr 9, 2020

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!)

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 · Apr 9, 2020

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.

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.

Hi!
Just gave dmesg | grep -i button again and this is the output:

[ 4.012866] input: Sleep Button as /devices/LNXSYSTM:00/LNXSYBUS:00/PNP0C0E:00/input/input3

[ 5.496297] psmouse serio2: trackpoint: IBM TrackPoint firmware: 0x0e, buttons: 3/3

And, yes - it used to work perfectly and every single time before.

So I was finally able to reproduce this. Unfortunately, I have no idea what the root cause is. I powered off my machine at least thirty times and tested. About half the time it’s working, the other times not.

When I run sudo journalctl -f in the terminal and then press the power button, I always see a message stating that the power button was pressed (i.e. the event is received) but on some boots, gnome-session-binary shows the shutdown dialog and it’s recorded in the journal; on other boots, nothing happens after the button event is recorded.

I even compared the journal entries from the working and non-working boots, but didn’t see any obvious differences.

Will keep digging around, but does anyone else have a hint or suggestion?

tomocafe · Apr 12, 2020

I submitted an issue to the Solus dev tracker. Still not sure if this is a Solus or Budgie issue, but I'm starting with Solus.

The report contains video and logs of it both broken and working. Same settings, different boots.

Thank you for submitting the issue tomocafe.

Yes, thank you!!
I'm interested to hear what will come of it!
