Suspend: Disable wakeup on mouse-move (Linux)
Posted: Thu Mar 07, 2013 2:36 pm
[PROBLEM]
Since upgrading to from Xubuntu 11.10 oneiric to LTS 12.04 precise, my PC would resume from suspend when the mouse moved. That might sound fun, but it's pretty annoying, considering that you touch the table to pick up something and the PC resumes again... hmpf.
[SOLUTION]
The following is closely based on a blog entry by "shadyabhi" on abhijeetr.com, but adapted to my setup (which had different wakeup-devices enabled).
In order to see what is enable to wake up your system from suspend, take a look at "/proc/acpi/wakeup", like this:
In my case the output was as follows:
I'm pretty sure that "PWRB" means "power button", and "GBE" means "GigaBit Ethernet", and it's obvious that "EUSB" and "USBE" relate to my mouse (because it's connected by USB) - Although I'm not so sure what exactly the difference "EUSB" vs "USBE" is.
However, I wanted only the power button and my network (WOL) to allow resume from suspend.
If you echo one of those "Device" abbreviation strings to /proc/acpi/wakeup, it toggles the state between enable/disabled.
So in my case I did (as root):
This toggled the enabled state of EUSB and USBE to disabled, leaving only "GBE" and "PWRB":
That change however is not permanent.
You could write a small script though, call it "acpi_wakeup" and put it in "/etc/init.d":
Make it executable:
Then use 'update-rc.d' to make the required symbolic links automatically in other directories:
Thanks shadyabhi, for your help!
