anyone here who can point me in the right direction?

[woodylongbone]

could it be some setting in grub? someone told me that if a machine works in tty, sooner or later it will hibernate. if so, where do I find grub settings?

I don't see how you can expect help with the information you posted.
What is a node?
Core does not have a scripts directory, so I have no idea what you are referring to.
Better questions get better responses.
