Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Power Management Modes
If you have VESA's DPMS compliance display card or software installed in your PC, the monitor can automatically reduce its power consumption when not in use. This is referred to as 'Power Save Mode'*. If input from keyboard, mouse or other input devices is detected by the computer, the monitor will automatically "wake up". The following table shows the power consumption and signaling of this automatic power saving feature:
VESA Modes Horizontal Sync Vertical Sync Video Power Indicator Power Consumption
Normal operation Active Active Active Green 70 W (maximum);
55 W (typical)
Active-off mode Inactive Inactive Blanked Amber Less than 3 W
Switch off - - - Off Less than 1 W
Note: The OSD will only function in the 'normal operation' mode. Otherwise one of the following messages will appear depending upon the selected input.
1. Analog Input
In Power Save Mode
Press Any Key on Keyboard or Move Mouse
2. Digital Input
In Power Save Mode
Press Any Key on Keyboard or Move Mouse
Activate the computer and 'wake up' the monitor to gain access to the OSD.
This monitor is ENERGY STAR-compliant as well as TCO '99/ TCO '03 power management compatible.
* Zero power consumption in OFF mode can only be achieved by disconnecting the main cable from the monitor.
ENERGY STAR is a U.S. registered mark. As an ENERGY STAR Partner, DELL has determined that this product meets the ENERGY STAR guidelines for energy efficiency.

*Note: USB 2.0 capability requires 2.0 capable computer
*Monitor's USB interface works ONLY when monitor is Powered ON (or in Power Save Mode). Switching your monitor OFF and then ON would re-enumerate its USB interface; attached peripherals may take a few seconds to resume normal functionality.
Plug and Play Capability
You can install the monitor in any Plug and Play-compatible system. The monitor automatically provides the computer system with its Extended Display Identification Data (EDID) using Display Data Channel (DDC) protocols so the system can configure itself and optimize the monitor settings. If desired, the user can select different settings, but in most cases monitor installation is automatic.
Doubt all the details from those 2 files are relavent, but I am no guru.
I then checked out xvidtune as root.
Did not really want to play with this as I am not really sure what each section does.
So I decided to just try moving the Hsync once to the right (just to see if it would do anything, was planning to change it back after) and received the following message:
Sorry: You have requested a mode-line, that is not possible, or supported by your hardware configuration.
I am assuming this is referring to the mode-lines for each resolution in the XF86Config file.
I then looked up modelines.
Found a site that explains how the values are calculated, but not what each parameter is responsible for.
I then checked the XFree86 Howto and either the information I am looking for is not there, or I just do not understand it.
All I want to know is what value for which parameter in which config file will adjust my display left-right up-down on a permanent basis.
OK this might seem like a really obvious question, but did you try to set the display from the monitor itself? Normally the monitor can be used to adjust the location, width, and height of the display, without going through the OS.
I currently run a triple-boot system where the display is exactly the same on all 3 OS'es, but I once had a dual-boot that had the display nicely in the middle of one, and off to the side on the other.
Anyway, I read your post but didn't see any reference to whether you tried this on the monitor.

When researching this before I had posted this, I had read that somebody else tried that to fix their Linux display, and when the booted into Windows, it was then messed up.
Would this happen?
Well as I said, this did happen to me once, it's not like the display screwed up it was just off to the side slightly. But I currently run Win98, Win2K and Linux (mandrake) on one computer at work and the display is the same for all 3.
Since you have dual boot, is it only off on Linux? What happens when you boot to Windows?
Try adjusting the monitor to make it look "perfect" in Linux and then boot into Windows and see if it's still the same. If not you can always switch it back.
