So far, I've force fsck (and I DESPISE systemd, oh, no, we *can't* let you
use /forcefsck, we'll ignore it, you need to change the grub2 command
line....), brought it up in runlevel 3, and no difference - startx gives
me the idiot screen, and hitting exit gives me a live screen - monitor's
not in power save, but black, blank, and it won't accept keyboard input.
And I can't make it let go without a reboot (at least doing what I've been
trying).

Yum doesn't seem to have a group-reinstall - I was going to try to
reinstall GNOME desktop.
