[SOLVED] What is suspending my computer when I leave it alone?

I just installed Arch for the second time, got mostly everything working smoothly, but despite having turned off automatic suspension in the settings (Cinnamon), something suspends it when I leave it alone for 10-15 minutes.

Any help with how to find out what's causing it and how to stop it is greatly appreciated.

Re: [SOLVED] What is suspending my computer when I leave it alone?

What have you installed?  Nothing out-of-the box will cause that.
Any interesting information in the journal?

Re: [SOLVED] What is suspending my computer when I leave it alone?

I've installed a variety of packages already, my main suspect is still Cinnamon, but perhaps it could be LightDM as well?

This is from where I believe such a suspension happened:

That first message at 15:47:27 was the first one in roughly 40 minutes, so as you can see all those messages pertaining to the suspension (from what I can tell) were entered over the course of two seconds. 18:00:20 was when I came home and woke it up again.

Re: [SOLVED] What is suspending my computer when I leave it alone?

Do you have power management settings that set your computer to suspend after a specific amount of time?

Re: [SOLVED] What is suspending my computer when I leave it alone?

Yes, and sometimes a question like that is all that's needed; I just realized I had switched up my A/C and battery settings. Thanks for the help.
