[Solved]Error Messages When Resuming Laptop

Whenever i close and open my laptop, these bizarre error messages display on my newly installed Arch machine:

my-ShittyLaptop login: [    156.873371] [drm:radeon_pm_late_init [radeon]] *ERROR* failed to create device file for dpm state
[    156.873569] [drm:radeon_pm_late_init [radeon]] *ERROR* failed to create device file for dpm state
[    156.873763] [drm:radeon_pm_late_init [radeon]] *ERROR* failed to create device file for power profile
[    156.873958] [drm:radeon_pm_late_init [radeon]] *ERROR* failed to create device file for power method

I tried googling the messages, but my problem appears to be more unique than i thought...

What steps would you take to troubleshoot this matter?

I would probably start by reading up on all components of the error messages
What are device files used for?
What is dpm state?
What is power profile?
How are they used?

Thanks, LCvanDinteren. Upon further inspection, it seems like this was a graphics problem. I remember now that i installed LightDM, but didn't install Xorg (as i thought it was included in arch base for some reason). Root Cause: PEBCAK.

:-P
