Those messages would not be triggered by an application. They can only be triggered by manually changing the power state via sysfs or via a display change event such as switching between single and multi display.
I think I have messed with the power state once by following the Arch Linux wiki, though the wiki said the methods provided would not be permanent so it isn't anything that I did right?
Are these errors responsible for the problems I am getting in OP?
Thanks again!
