LCD can't support input signal

SuSE 9.2 Pro

Just got a nice birthday present, an Acer 1913b LCD display. I connected it,
and it was not able to start using the existing signal. No problem. I
reconnected the old CRT, started YaST and Hardware config, video card and
monitor, put the mouse pointer over the "Re-probe" button, then disconnected
the CRT, reconnected the LCD and clicked. The system found the new display
and immediately began ... well.... displaying, at 1280 x 1024, as
advertised.

Kewl!

So I saved and exited, and went happily about my business in KDE.

Then my wife wanted to open a session.
No problem, just [Ctrl][Alt][F1], log in, and type "startx -- :1" to start a
new X session on F8, right? Well, not quite.

As soon as the [F1] session becomes live, the Acer goes blank and reports
"Input signal not supported". There's something about that enhanced-text
session (with the blue suse bar, top and bottom), that it doesn't like.
Probably some obscure horizontal and vertical or dot-clock numbers.

Well, I can log in blind and type the startx command blind, and get my
second session (which does display nicely at [F8]. But I really want to have
my [F1] text-based terminal session back.

Similarly, the Acer does not support the input during the Linux startup. You
know, that splash-screen that says press [F2] for details? Doesn't work.
Can't see the silly splash screen, and can't see the boot messages. It's
three solid minutes of blankness until the kdm login screen appears.

Currently, I'm set to start in run level 5. Is there a way to modify the
parameters of that splash-screen and graphic/text boot-message display? I
like it because it gives the green and red visual clues for "done, done,
done" versus "failed" when a service or device doesn't load.

Has anybody else met this?

Kevin (really wanting to keep his new flat panel, but not wanting to keep an
old 19-inch CRT on standby)
