Ubuntu 24.04.2 LTS:
How to configure ACPI wakeup devices?:
The default setting of many ACPI devices after bootup is “enabled”:
See:
# cat /proc/acpi/wakeup
Example output on my system directly after bootup:
Device S-state Status Sysfs node
P0P9 S1 *disabled pci:0000:00:1e.0
EUSB S4 *enabled pci:0000:00:1d.0
USBE S4 *enabled pci:0000:00:1a.0
PEX0 S4 *enabled pci:0000:00:1c.0
PWVE S4 *enabled pci:0000:06:00.0
NPE1 S4 *enabled pci:0000:00:01.0
NPE4 S4 *disabled
NPE5 S4 *disabled
NPE6 S4 *disabled
NPE8 S4 *disabled
NPEA S4 *disabled
NPE2 S4 *enabled pci:0000:00:01.1
NPE3 S4 *enabled pci:0000:00:02.0
NPE7 S4 *enabled pci:0000:00:03.0
NPE9 S4 *disabled
SLPB S0 *disabled
NPE2 S4 *disabled
NPE4 S4 *disabled
NPE5 S4 *disabled
NPE6 S4 *disabled
NPE8 S4 *disabled
NPE9 S4 *disabled
NPEA S4 *disabled
NPE1 S4 *disabled
NPE3 S4 *disabled
NPE7 S4 *disabled
As you can see, USB events are configured as wakeup events, and more.
So I have to toggle the devices enabled to disabled.
I did this using acpitool -W.
After having done this, suspend/hibernate work fine, do no longer insta-return.
However, as soon as the computer gets rebooted, the settings get lost and are again “enabled” as shown above.
Question:
Is there a way to configure the ACPI wakeup state of devices to a particular state, either “enabled” or “disabled” after boot?
