My problem is the opposite of what is described in How to prevent resume from sleep/suspend on lid open?.

If I close my laptop's lid, it automatically suspends, but when I open it up again, nothing happens, and I have to press the power button to wake it up.
How can I make my laptop wake up from suspend when I open it's lid?

( It's an acer v5-171 running Ubuntu 13.10)

Have you seen this post? It looks like the method worked for one guy but not the other, so its not a guaranteed fix, but its worth a shot. : )

Here's a brief summary:

You can check whether the Lid open event is configured to wake up your OS by executing
cat /proc/acpi/wakeup. If the status of LID or LID0 is disabled you can try enabling it by executing

sudo -s
echo "LID" > /proc/acpi/wakeup

This will set the status to enabled, and executing the commands again will set it back to disabled.

This needs to be supported by hardware through a sensor for the lid-open event. Unless your hardware supports it, there would be "no-one" who will get notified of the "lid-open" event, and wake your laptop.

Go to system utilities and then go to system settings. From there you will pick boot options and scroll down until you see power up on lid opening. Activate and apply.
