The power button on the jetson nano devkit carrier board is How is the action?

Hello,

The power button on the jetson nano devkit carriere board is
How is the action?

Does long press turn it off?
I used to change the way the power button works through gsettings.
Jetson nano seems to go into suspended when not logged in ubuntu.

Thank you.

Hello,

Connect the power button to the devkit carrier board as follows and
I press the power button on the screen before logging in to ubuntu
It seems to go into suspended mode.
If you press the power button again, the login standby screen appears immediately without booting up.
Is it possible to shutdown without going into suspended mode in this situation?

When the HDMI cable is not connected, it does not enter suspended mode even when the power button is pressed.
As soon as the HDMI cable is connected, it goes into suspended mode.

Here’s what I checked with journalctl:

Thank you.

hello Hodu,

please dig into device tree for gpio-timed-keys.
it’s press-times-secs to specify the times in seconds linked with different key-codes,
for example,

        gpio-timed-keys {
                power {
                        linux,press-time-secs = <1 3 5>;
                        linux,key-codes = <KEY_DOWN KEY_DISPLAYTOGGLE KEY_ENTER>;
