F8 display misbehaving

[Beartooth]

1916	The display on my main F8 machine looked a little odd; so I went 
to Main Menu > System > Administration > Display ; gave the root 
password ; found it set to the next bigger monitor than my Acer AL1916, 
which is 1280x1024 -- despite the fact that Fedora on that machine (but 
not my others) does recognize the monitor. (The others, behind the same 
KVM switch -- all installed with peripherals connected directly, *not* 
behind the switch -- don't even list it, and have to be set for generic 
LCD 1280x1024.)

	Then I logged out and back in.

	The display still looks odd, though in a different way. 

	But it won't let me tinker. I get as far as giving the root 
password, but the system-config-display GUI, or whatever it is, never 
launches!
