Suddenly, on a machine which has been running F7 since F7 came out, I can no longer log in.
Instead of the usual login screen, I get a gray window without the usual bar on top, which first says it is scanning the local network, and then that "No serving hosts were found."
If I type in 127.0.0.1, or localhost, or localdomain, or its 192.168.x.y, or lo, or localhost.localdomain, or localhost@localdomain, and try to add it, I get a new box with a "do not enter" symbol and the title "Did not receive response from server," below which is a paragraph saying it didn't get it in 3 seconds, and adding "Perhaps the host is not turned on, or is not willing to support a login session right now. Please try again later." Or if not that box, one (particularly for lo) suggesting that I might have mistyped it.
If I ssh into it from another machine behind the same router, however, it accepts that; and /sbin/ifconfig confirms its own 192.168.x.y, its proper MACs (one for eth0 and one for eth1), and the 192.168.x.y for the machine I'm working from.
If I look at "cat /etc/X11/xorg.conf" I see nothing obviously strange except that there are an awful lot of modes (twelve of them) in Section "Screen" -- but the first one, 1280x1024, is correct for my monitor, which another section correctly identifies an an lcd.
If I become root and ssh into the problem machine, it lets me; but when I try telling it startx, it claims X is already running.
If, as it suggests, I remove /tmp/.X0-lock, and try startx again, I get several screenfuls of messages, which I can't even scroll back to -- and startx|less does the same!
What have I fouled up so royally this time, and what (if possible, short of reinstalling F7) can I do about it? (I know perfectly well how helpless I am without a GUI; it doesn't have to rub my nose in it.)

Shrug. mv /etc/X11/xorg.conf to backup. setup x window setup perhaps that will get you a fresh as detected config.
What has changed since it last worked ? different screen ? screen plugged in a different video output ? fedora updates ?

Well, I tried all that, several different ways, over ssh; and never reached a stage where I could log directly into the machine itself.
So I finally took a deep breath, and hit it with the big hammer. Fresh install, this time with the DVD in an external drive -- but with K, V, & M connected directly, not through the KVM switch. (I've still had to re- change the display a couple of times. It seems to want to believe it has either an 800x600 or a 1900x1200 screen -- or a CRT instead of an LCD.)
I'll get most of my configuration back, by scp-ing it in from another machine, as I've described here -- but first I have to make sure all the right apps are installed, including some such as Pine and Opera which yum doesn't handle. (Nor does even pirut.)

I wish I knew.

I make a guess: maybe you set your graphical login manager to make a remote login? I know similar windows from KDM. Search for a option to make a local login.
If I type in 127.0.0.1, or localhost, or localdomain, or its 192.168.x.y, or lo, or localhost.localdomain, or localhost@localdomain, and try to add it, I get a new box with a "do not enter" symbol and the title "Did not receive response from server," below which is a paragraph saying it didn't get it in 3 seconds, and adding "Perhaps the host is not turned on, or is not willing to support a login session right now.

Is does not seem right for me to enter a server name in order to login locally.
Another question: can you login on local console? This ugly ;-) textual thing you can reach with Ctrl-Alt-F1 (usually Ctrl-Alt-F7 brings you back to the graphical console). If you can, there is nothing wrong with your account.
