I'm running Freya on a MacBook Pro 2013 edition.
Suspend doesn't ever work as planned. It takes quite a while to actually get to sleep and it'll often wake itself back up again, and when it does, it seems to have taken out the entire networking stack and neither my USB 3 Ethernet adapter nor my wireless USB dongle work any more.
The main problem is that it always suspends when the lid is closed, which I want to never happen.
Is there a way to fully prevent it from ever suspending? I'm using it with 2 DisplayPort monitors right now, but I can't close the lid for fear that it'll suspend itself and screw everything up.
