First, you need to start up at run level 3 instead of 5. From the Red Hat 9
Reference Guide, page 21:

2.10. Changing Runlevels at Boot Time
Under Red Hat Linux, it is possible to change the default runlevel at boot
time.
If using LILO, access the boot: prompt by typing [Ctrl]-[X]. Then type:
linux

runlevel-number

In this command, replace

runlevel-number

with either the number of the runlevel to boot
into (1 through 5), or the words single or emergency.
If using GRUB, follow these steps:
• In the graphical GRUB boot loader screen, select the Red Hat Linux boot
label and press [e] to
edit it.
• Arrow down to the kernel line and press [e] to edit it.
• At the prompt, type the number of the runlevel you wish to boot into (1
through 5), or the words
single or emergency and press [Enter].
• You will be returned to the GRUB screen with the kernel information. Press
the [b] key to boot the
system.

The following is from the Red Hat 9 Getting Started Guide, page 76.

10.4. Troubleshooting Your Video Card
Video card configuration is handled during the Red Hat Linux installation
(refer to the Red Hat Linux
Installation Guide for more information). However, if you did not choose to
configure a video card at
that time, or if you need to reconfigure your settings, you can use the X
Configuration Tool utility.
You should do this, for example, if you install a new video card.
Note
The X Configuration Tool backs up your system's original video configuration
file to
/etc/X11/XF86Config.backup in case you need it to switch back to a previous
configuration.
To run the X Configuration Tool, click Main Menu => System Settings =>
Display. A pop-up
window prompts you for your root password. You can also start from a shell
prompt by typing the
command redhat-config-xfree86, which then prompt you to input your root
password. If you
are working from a shell prompt and X is not working, redhat-config-xfree86
attempts to start a
minimal X session to allow you to continue your configuration. Follow the
instructions that appear on
the screen. X Configuration Tool attempts to automatically configure your
video card and monitor
settings for you. Figure 10-6 shows the Advanced tab for configuring your
video device manually.
Figure 10-6. X Configuration Tool
To configure your monitor manually, click the Advanced tab, then click the
Configure... button next
to the Monitor Type entry. A pop-up window will display a list of monitor
models. Choose your
model and click OK. You can also let X Configuration Tool probe your monitor
for the correct
model and vertical/horizontal frequency settings.
To configure your video card manually, click the Advanced tab, then click
the Configure... button
next to the Video Card entry. A pop-up window will display a list of video
card models. Choose your
model and click OK. You can also let X Configuration Tool probe your video
card for the correct
model and settings by clicking the Probe Videocard button.
When you have finished reconfiguring your video card and monitor, you should
be able to start an X
session and enjoy your graphical desktop environment.

--------------

Note that X Configuration Tool (which is presumably what you were using)
creates a backup, so your first try might be simply

cp /etc/X11/XF86Config.backup /etc/X11/XF86Config

and reboot normally.

And if it turns out you need to reconfigure, it says the X configuration
tool will usually work directly from the command line with the command

redhat-config-xfree86
