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.


You could install Caffeine from ppa:caffeine-developers/ppa.

It runs as an indicator and can be used to prevent suspension.

You can also try this method, taken from Ask Ubuntu:

For me it is important to just disable the "automatic Suspend" Because I still want to be able to do the "manual Suspend" in /etc/polkit-1/localauthority/50-local.d/com.ubuntu.disable-suspend.pkla

So, I used:

[Disable suspend (upower)]

[Disable suspend (logind)]

[Disable suspend when others are logged in (logind)]

Now I can click "Suspend" in the logoff menu. But the PC keeps running unless I send it to "Suspend".

  • Thanks for the tip, but I don't have that file on my computer. Nothing exists in 50-local.d. I'll look elsewhere. – Naftuli Kay Aug 3 '15 at 18:59
  • @NaftuliTzviKay use locate from the command line to find the file. – RolandiXor Aug 4 '15 at 17:11
  • I did. There's nothing with a similar name. – Naftuli Kay Aug 4 '15 at 17:11
  • You may have to create the file. – RolandiXor Aug 4 '15 at 17:12
  • Noted. I'll look into it. – Naftuli Kay Aug 4 '15 at 17:12

I use elementary OS freya and there is a GUI app for powermanagement. Remove all instances of sleep, suspend and hibernate. You can leave turn the display off.

That disables automatical suspend, but will leave the manual suspend up in the menu in the right upper corner. Mbr Patte
