Changing the screen refresh rate... without the screen
I've installed Knoppix (as the Debian installation) to the hard drive, and everything worked fine. I changed from a CRT monitor to a nice LCD screen, so that it would clutter less space. A little problem: the LCD won't take the vertical/horizontal refresh rate that the old CRT could use. I need some help figuring out which command(s) reduce(s) this rate so I can properly view this screen. Thanks, and I would appreciate any help.

Boot computer off Knoppix cd. Knoppix will query monitor settings and store results in either /etc/X11/xorg.conf or /etc/X11/XF86Config-4. Compare this with the settings in /etc/X11/xorg.conf or /etc/X11/XF86Config-4 in the root partition of your hd installation. Edit the settings of your hd installation to match those of the live cd. This should do the trick.

Um, I see what you're talking about. Another little issue: I'm also new to the scene of a Debian HD-Installation. I can't seem to save those settings into the original file. Otherwise, I believe the system can work. Running Konqueror as root gives me all sorts of permission and system process problems. Oh, and another thing: the HD-Installation version is 5.0.1, while the cd version is 4.0.2- is that part of the problem?

Launch "Root Konsole" from the Knoppix menu. At the prompt enter
Code:
mount -o rw /dev/hda1 /media/hda1
mcedit /media/hda1/etc/X11/xorg.conf
Replace "hda1" with the label of the root partition of your hard drive installation. Press "F2" to save to file, "F10" to quit.
When you're done editing, unmount the drive:

I was able to successfully edit that file- thanks for the help!
But another problem to the list- Knoppix refuses to start XDM because it's "not the default display manager." After, it acts just like Konsole- asking for a username and password, in which I can use my root and personal account.

What do /var/log/syslog and /var/log/Xorg.0.log say?

Well, it appears the screen's the problem- or so it seems:

I suspect it may be how I edited Xorg.conf.

in the hard drive install, there is no /etc/X11 directory.

The folder exists. There is definitely something wrong your hard drive install. Better check the cd and install again.
