I was working out a display driver problem. It turned out I took the nvidia wiki article too seriously, and masked the package back to too old of a version.
That problem has been "fixed," though it presents an entirely new problem. Turns out the nvidia install script that I had played with as a solution had installed "correctly" enough to function beforehand, and there is some aspect of configuration that makes x go black. This problem persists in the freshyly emerged version, only now it starts x on boot,... And I'm running an EFI stub (no GRUB) with higher precedence than my usb... Shoot...
Good news...terminal is running fine behind the blackness. I can log in and reboot (at least I think I am logging in.. The command I found to stop (what was it again?--i'm on my tablet can't look up easily..) Xdm (gkx)dm has no effect. Neither does Ctrl+Alt±Bckspce (I sure wish that was enabled by default)
So how bout it? Know any good ammo-clips of one liners to take down X? I worked so hard on that custom kernel(more than just the stub) 'don't really want to scrap it with the Apple USB recovery.
