4.8. OK, without rebooting, how do I completely disable LIDS?

Besides using an LFS, LIDS can be turned off globally. This will only work if you compiled the option into your kernel.
bash# lidsadm -S -- -LIDS_GLOBAL
When LIDS_GLOBAL is disabled, your system will operate like a "normal" Linux system. To re-enable LIDS globally, perform the opposite:
bash# lidsadm -S -- +LIDS_GLOBAL
NOTE: This will not affect your LFS if you currently have one enabled.
