How do I make changes to /proc/acpi/wakeup permanent?
- by Jolan
I had a problem with my Ubuntu 12.04 waking up immediately after going into suspend. I solved the problem by changing the settings in /proc/acpi/wakeup, as suggested in this question: How do I prevent immediate wake up from suspend?.
After changing the settings, the system goes flawlessly into suspend and stays suspended, but after I wake it back up, the settings in /proc/acpi/wakeup are different from what I set them to.
Before going to suspend:
cat /proc/acpi/wakeup
Device S-state Status Sysfs node
SMB0 S4 *disabled pci:0000:00:03.2
PBB0 S4 *disabled pci:0000:00:09.0
HDAC S4 *disabled pci:0000:00:08.0
XVR0 S4 *disabled pci:0000:00:0c.0
XVR1 S4 *disabled
P0P5 S4 *disabled
P0P6 S4 *disabled pci:0000:00:15.0
GLAN S4 *enabled pci:0000:03:00.0
P0P7 S4 *disabled pci:0000:00:16.0
P0P8 S4 *disabled
P0P9 S4 *disabled
USB0 S3 *disabled pci:0000:00:04.0
USB2 S3 *disabled pci:0000:00:04.1
US15 S3 *disabled pci:0000:00:06.0
US12 S3 *disabled pci:0000:00:06.1
PWRB S4 *enabled
SLPB S4 *enabled
I tell the system to suspend, and it works as it should. But later after waking it up, the settings are changed to either:
USB0 S3 *disabled pci:0000:00:04.0
USB2 S3 *enabled pci:0000:00:04.1
US15 S3 *disabled pci:0000:00:06.0
US12 S3 *enabled pci:0000:00:06.1
or
USB0 S3 *enabled pci:0000:00:04.0
USB2 S3 *enabled pci:0000:00:04.1
US15 S3 *enabled pci:0000:00:06.0
US12 S3 *enabled pci:0000:00:06.1
Any ideas?
Thank you for your response. Unfortunately it did not solve my problem.
all of
/sys/bus/usb/devices/usb1/power/wakeup
/sys/bus/usb/devices/usb2/power/wakeup
/sys/bus/usb/devices/usb3/power/wakeup
/sys/bus/usb/devices/usb4/power/wakeup
as well as
/sys/bus/usb/devices/3-1/power/wakeup
are set to disabled, and the notebook still wakes up by itself right after going to sleep. The only thing it seems to react to are the settings in /proc/acpi/wakeup, which keep changing (resetting) every time i power off/restart my notebook.
