In Windows Vista, configuring dual-displays was trivial; the Nvidia driver detected the extra monitor and let me configure it using the Nvidia Control Panel utility. In Fedora 7 Linux, it was slightly more challenging to get the desired TwinView dual-display configuration to work. First, I installed the correct Livna-Nvidia graphic drivers by following the instructions here. Using the Nvidia drivers packaged with Fedora is a mistake. Use the Livna packaged Nvidia drivers, you'll be much happier in the long run.

Here's the dual-display Device section of my xorg.conf file that I use when the notebook is docked in a docking station. Attached to the docking station I have a single flat-panel connected to the DVI out port. This dual-display configuration uses the DVI digital flat-panel in addition to the notebook's built-in display:

Here's the dual-display configuration I use at work, where I have two flat-panels plugged into the docking station. One display is connected to the DVI out and the other is plugged into the VGA out on the back of the docking station:

Here are the three monitor configurations, and related xorg.conf files, I use with my HP 8510w:
- Dual display, no docking station. 1st display is the laptops built in display. The 2nd display is plugged into the VGA external monitor out port on the back of the notebook.
xorg.conf.config_1.txt - Dual display, with a docking station. The 1st display is the laptops built in display. The 2nd external display is plugged into the DVI out (white) on the back of the docking station.
xorg.conf.config_2.txt - Dual display, with a docking station. 1st display is plugged into the VGA out (blue) port and the 2nd display is plugged into the DVI out (white) on the back of the docking station. The HP 8510w only supports two displays, so in this configuration, the built in display is disabled.
