power_manager, display wakes up

xubuntu 18.04 desktop
new install

Using xfce4-power-manager.   Suspend seems to work as expected.   Display blanks out when expected, but wakes up about 23 seconds later.

Re: power_manager, display wakes up

Not sure if this is the right place for this, but from an xfce4-power-manager perspective, try running it in debug mode:

xfce4-power-manager -q && xfce4-power-manager ---no-daemon --debug

...attempt a suspend and when it returns, have a look at (and post back) the output from the above command.

From a systemd perspective, you'l want to look at the journal to see if you can identify the cause. Commands that might help:

systemctl status systemd-suspend
systemd-inhibit
sudo journalctl -u systemd-suspend
cat /proc/acpi/wakeup

Also:

sudo journalctl -b 0 --no-pager

...and look at the entries around the time that the suspend event happened.

From your original description, it sounds like the system suspends and then something (not you) wakes it up. Is this correct?

Can you post the complete results of those commands? Sometimes the messages that aren't warnings are also useful information.

Re: power_manager, display wakes up

Sorry, I wasn't very clear.   Its Display Power Management.    On Power Manager-Display, I can set Display Power Management to Blank after x, Put to sleep after x, or Switch off after x.  I tried setting any of these to 1 and the display goes dark in 1 minute, but then it wakes up about 23 sec later.    System Power Saving-Suspend seems to work as expected.    I think xfce power management is working, but some wakeup signal comes in.    Thanks for the help, let me know what else I can do.

Re: power_manager, display wakes up

Thanks for the clarification. Unfortunately, there is nothing in that log file that indicates a wake signal. Does it include the time when the monitor work up?

I have read of instances where very sensitive mice can register movements that result in wake-up events. What kind of computer do you have? Are you able to unplug and/or disable the mouse for a test?

Something else that might wake the computer might be a notification. If you are using xfce4-notifyd, try killing that process as a second test.

Re: power_manager, display wakes up

I unplugged the mouse, the keyboard and the usb drive.    No change, still a wakeup about 23 sec later.

I looked at all the files in /var/log that had been touched since the last wakeup,   Xorg, syslog, auth.log, kern, nothing logged at the time of the sleep or wakeup.
Surely this has to be logged somewhere?

I don't know what all these devices are, but should I disable some?
