Disable suspend when pressing fn+F4

Question

I have a System 76 laptop with Oneiric. I just tried to turn the volume down using fn+F5 but I accidentally pressed fn+F4 and suspended the system instead. Is there a way to disable that so I won't make the mistake again?

Answer 1

If you look into this directory

ls /etc/acpi/events/

then there should be somewhere a sleep-button-file. In this file you could disable the action when this event is sent.

Answer 2

I could only solve this issue by
1) Editing the file /etc/acpi/sleep.sh (gksu gedit /etc/acpi/sleep.sh) and
2) Putting # before pm-suspend.

If you are lazy, just paste this on a terminal (a backup will be created):

sudo sed -i".bak" 's/pm-suspend/\#pm-suspend/' /etc/acpi/sleep.sh
