- Make sure that the nVidia driver has been installed and is functioning properly on your first screen. Also, make sure both monitors are connected.
- Open the command-line terminal Konsole and type:
- Select "X Server Display Configuration".
- You should see 3 boxes (2 if your card doesn't have an S-Video out). From here you can configure all of your card's outputs.
- Check the "(Disabled)" box.
- Select "Configure...".
- The most common choice is TwinView. Select it.
- Setup the desired screen resolutions and positions of your two active displays.
- The new display will likely have resolution set to "Auto" to match your first. Change this if you wish.
- Leave the first screen's position as "Absolute" and set your second display's position relative to that.
- "Clone" means the same output on both.
- Once you are satisfied with your settings, hit Apply to test them.
- Note: if your displays are side-by-side, the kicker may extend across both screens as well as any maximized applications. This will be corrected when the X server is restarted.
- If everything else is ok, hit "Save to X Configuration File". Now hit Ctrl+Alt+Backspace to restart X. You now have 2 screens!
- (The NVIDIA X Server Settings application can be also found in K -> System Settings to change settings later, but this does not always work because settings need to be changed as the root user.)
- Troubleshooting: if the X server fails to reload you can recover your old X configuration. In a terminal:
sudo cp /etc/X11/xorg.conf.backup /etc/X11/xorg.conf
