Hi,
in Windows closing the lid makes it going to sleep and opening the lid makes it resuming.

I am using Ubuntu 13.10 on my Samsung Series 7 Chronos 700Z3A-S02DE. When I close the lid the laptop suspends, but on lid open it does not resume until I press the power button. With acpi_listen I see that it fires and recognizes the events for lid close and open and /proc/acpi/button/lid/LID0/state shows the correct state for each lid position. With acpid -d -f -l
I see that those events trigger /etc/acpi/events/. I wrote an event that matches lid close/open and calls pm-suspend. But this does not make the laptop resume.
I also uncommented the lines in /etc/systemd/logind.conf regarding hibernate and suspend. But this does not work either.

So my problem is that the system receivs and understand those ACPI events triggered from the lid actions. But LID0 is not configured as /etc/acpi/wakeup device. Nor echoing it into the file does make it appearing there. So I am at the end of my knowledge and understanding of the ACPI event handling.

I've already tried to pass different acpi_osi Strings with grub but the ACPI table does not change nor make it any difference for the suspend/resume problem.

If I can give any further information please just ask me to. Thank you.
