The normal default thing for *laptops* is to go to sleep when the lid is closed. This not specific to any distro, desktop, or even O/S. If you really want to do things like ssh into your laptop when the lid is closed, you need to disable "sleeping". Note: this *might* be a problem in terms of battery life, so you should be sure about this and/or make sure sleep is re-enabled when "on the road".
The sleep controls are usually under "power management". It is easy enough to disable "sleep when idle". It *might* be more tricky to disable "sleep on lid closure". (On my MacBook [like I said above not O/S specific] it required a more invasive CLI command to disable sleep altogethed -- my MacBook never travels and is always plugged in.)
