Howto prevent anything but power button waking up system from suspend?

Hello,

I recently installed XUbuntu using XFCE on my laptop, and I have really struggled a lot to make suspend mode reliably not doing anything to wake up my system except for a short press on the power button, i.e. no mouse movement, no keyboard presses, nothing should allow the system to wake up.

1.) I have (nearly) handled the Keyboard/mouse issue by writing a short script in /etc/init.d/usbwakeup that is launched automatically at startup. Before the script runs, it looks like this:

grep . /sys/bus/usb/devices/*/product
/sys/bus/usb/devices/1-2/product:USB Composite Device
/sys/bus/usb/devices/1-4.1/product:2.4G Keyboard Mouse
/sys/bus/usb/devices/1-4/product:USB2.0 Hub
/sys/bus/usb/devices/usb1/product:xHCI Host Controller
/sys/bus/usb/devices/usb2/product:xHCI Host Controller
grep . /sys/bus/usb/devices/*/power/wakeup
/sys/bus/usb/devices/1-2/power/wakeup:enabled
/sys/bus/usb/devices/1-4.1/power/wakeup:enabled
/sys/bus/usb/devices/1-4/power/wakeup:disabled
/sys/bus/usb/devices/usb1/power/wakeup:disabled
/sys/bus/usb/devices/usb2/power/wakeup:disabled

After I run my script:

echo disabled > /sys/bus/usb/devices/1-2/power/wakeup
echo disabled > /sys/bus/usb/devices/1-4.1/power/wakeup

Everything looks like this:

grep . /sys/bus/usb/devices/*/power/wakeup
/sys/bus/usb/devices/1-2/power/wakeup:disabled
/sys/bus/usb/devices/1-4.1/power/wakeup:disabled
/sys/bus/usb/devices/1-4/power/wakeup:disabled
/sys/bus/usb/devices/usb1/power/wakeup:disabled
/sys/bus/usb/devices/usb2/power/wakeup:disabled

This works perfectly fine after a restart, but after some repeated testing with suspend-actions, the settings get reverted to enabled for the two USB dewvices 1-2 and 1-4.1, and I have no clue why this happens. Does anybody have an idea?

2.) Even more annoyoing, I managed to handle that the laptop lid is ignored when closing, but as soon as I open the lid, my system wakes up. What might I try to prevent the lid when opened from switching on the computer?

I already tried the following:
In logind.conf, I added the following lines:

HandleHibernateKeyLongPress=ignore
HandleLidSwitch=ignore
HandleLidSwitchExternalPower=ignore
HandleLidSwitchDocked=ignore

And in UPower.conf:

IgnoreLid=true

Nothing of that helped. Closing the lid is actually ignored, but opening activates the system instantly. Any ideas? Thank you for all hints you may have.

Last I checked this was an issue on my Manjaro Xfce also. I agree that mouse moving should not wake it from sleep.

Here's hoping you find a solution.

It sounds like maybe on resume the device gets re-recognized and treated like new - resetting the wakeup settings. Look at creating udev rules to disable wakeups on device recognition.

Look at bypassing power management handling to logind, then those settings would take priority.
