Configuring Multiple Screens on the Toshiba M10 Notebook With NVIDIA Graphics
You can configure the internal LCD panel and an external monitor connected to the Toshiba M10 notebook in one of the following ways:
• Cloned mode. Presents the same graphics on both displays. This mode is most useful in environments where you are presenting the same materials to multiple viewers, such as for a class, seminar, or presentation.
• Spanned mode. Stretches a single X screen across both displays where windows can cross the the physical display boundaries. This mode is most useful when you want a larger desktop.
• Separate mode. Creates two independent X screens for each display. While the cursor can cross from one display to the other, windows cannot. This mode is most useful when different attributes are needed for each display or when using StarOffice to show a full screen presentation on the external display (Slide Show -> Slide Show Settings... -> Presentation monitor).
How to Configure Cloned Mode
1. Start the NVIDIA configuration program.
Go to Preferences -> NVIDIA X Server Settings.
2. Select X Server Display Configuration from the menu on the left.
Only the M10 panel appears if the external display was not connected when the desktop was started.
3. Connect the external display and click Detect Displays.
The external display will appear in the Layout panel:
4. Select the external display in the Layout panel or choose from the Model drop-down menu.
The display that is being configured is highlighted in red.
5. Click Configure.
The Separate X Screen and TwinView choices are shown.
To mirror the two displays, choose TwinView, and click OK.
6. Choose Clones from the Position drop-down menu.
The Layout panel now shows the two displays aligned at their upper lefthand corners.
7. Click Apply and confirm the video mode change when prompted.
8. Click Configure, and select Disabled to disable the external display when it is no longer needed.
How to Configure Spanned Mode
1. Start the NVIDIA configuration program.
Go to Preferences -> NVIDIA X Server Settings.
2. Select X Server Display Configuration from the menu on the left.
Only the M10 panel appears if the external display was not connected when the desktop was started.
3. Connect the external display and click Detect Displays.
The external display will appear in the Layout panel:
4. Select the external display in the Layout panel or choose from the Model drop-down menu.
The display that is being configured is highlighted in red.
5. Click Configure.
The Separate X Screen and TwinView choices are shown.
To mirror the two displays, choose TwinView, and click OK.
The position of the displays in the Layout panel can be moved by dragging them with the left mouse button pressed. Alternately, use the Position drop-down menu to reposition the displays to the right, left, above, or below.
The Layout panel shows the 1600x1200 CRT on the left:
Note that the area under the internal LCD represents pixels that will not be visible due to the mismatched display resolutions.
To enable panning to gain access to these pixels, click Advanced and choose the internal panel:
To enable panning on the area below the internal LCD, set the panning domain to 1440x1200 to match the vertical resolution of the CRT on the left.
This area in the Layout panel will change color to indicate that it is now part of the panning domain:
Virtual panning works by moving the cursor to the top or bottom edge of the display to shift the screen area up or down.
6. Click Apply and confirm the video mode change when prompted.
7. Click Configure, and select Disabled to disable the external display when it is no longer needed.
How to Configure Separate Mode
1. Start the NVIDIA configuration program.
Go to Preferences -> NVIDIA X Server Settings.

The position of the displays in the Layout panel can be moved by dragging them with the left mouse button pressed. In this example, the CRT is physically located on the left, but the panel default places it on the right.
The Layout panel now shows the 1600x1200 CRT on the left after dragging it with the mouse.
6. Click Save to X Configuration File to create an X configuration file in your home directory.
As a privileged user, copy the xorg.conf file in your home directory to /etc/X11.
7. Log out from the desktop and log in again to use the updated X configuration.
