This information is called EDID information. Creating a `ModeLine` from this is just a matter of putting the numbers in the correct order:
ModeLine <name> <clock> <4 horiz. timings> <4 vert. timings>
So that the `ModeLine` in `Section "Monitor"` for this example would look like this:
Section "Monitor"
Identifier "Monitor1"
VendorName "Bigname"
ModelName "BestModel"
ModeLine "1680x1050" 146.2 1680 1784 1960 2240 1050 1053 1059 1089
Option "DPMS"

Troubleshooting Compiz Fusion
I have installed Compiz Fusion, and after running the commands you mention, my windows are left without title bars and buttons. What is wrong?
You are probably missing a setting in [.filename]#/etc/X11/xorg.conf#. Review this file carefully and check especially the `DefaultDepth` and `AddARGBGLXVisuals` directives.
When I run the command to start Compiz Fusion, the X server crashes and I am back at the console. What is wrong?
If you check [.filename]#/var/log/Xorg.0.log#, you will probably find error messages during the X startup. The most common would be:
(EE) NVIDIA(0): Failed to initialize the GLX module; please check in your X
(EE) NVIDIA(0): log file that the GLX module has been loaded in your X
(EE) NVIDIA(0): server, and that the module is the NVIDIA GLX module. If
(EE) NVIDIA(0): you continue to encounter problems, Please try
(EE) NVIDIA(0): reinstalling the NVIDIA driver.
This is usually the case when you upgrade Xorg. You will need to reinstall the package:x11/nvidia-driver[] package so glx is built again.
