    I was bothered by a large amount of logs like this appearing in syslog, and it stopped when I stopped dmprovider.service.
    What kind of service is this?

    thanks replay.

    $ sudo ethtool -s eth0 wol g
    $ sudo nmcli connection modify eth0 802-3-ethernet.wake-on-lan magic
    $ sudo nmcli connection up eth0

    These three commands enabled wol and shutdown.
    I ran the following command from another linux, but it doesn't start.


    $ sudo etherwake <mac address>
    $ wakeonlan <mac address>


    Am I missing something?

    I'd like to use an overlay file system like the one implemented in raspi-config on my raspberry pi, but it doesn't work.
    I referred to this site, but the boot partition is not large enough to create an initramfs image.

    https://yagrebu.net/unix/rpi-overlay.md

    /dev/mmcblk0p7  4.9M  348K  4.3M   8% /boot
    Is there a better way?

    The 29th pin is set to 1 in the gpio readall command.
    3.3V was measured with a voltmeter between GND and pin.
    I'm not sure why, but inserting add_event_detect solved it.
    why? 

    import ASUS.GPIO as GPIO
  
GPIO.setmode(GPIO.BOARD)
GPIO.setup(29, GPIO.IN)

GPIO.add_event_detect(29, GPIO.BOTH)

print(GPIO.input(29)) # <- 1

    I am programming with reference to the sample.
    How can I see the 0,1 of the GPIO?
    The 29th pin shows 3.3V when I look at it with a tester.
    It will be 0 when printed. 

    import ASUS.GPIO as GPIO
  
GPIO.setmode(GPIO.BOARD)
GPIO.setup(29, GPIO.IN)

print(GPIO.input(29))
