Ubuntu – How to prevent mouse movement from waking up a suspended computer


It's really annoying as I have to unplug the mouse after a suspend to ensure that an occasional bump doesn't wake up the system. I haven't found anything in system settings which could disable this neither by googling around.

I haven't checked the BIOS yet, but I've found a solution!

Short summary: In /proc/acpi/wakeup, you can see which devices are currently enabled to resume from suspend. That list shows names (abbreviated) of so called "Devices". Example "PWRB" means "power button".

If you write device-names to that file, you toggle them between enabled/disabled.

I wrote a small HowTo for disabling wakeup-by-mouse, based on a blog where I found that info.
