Setting up your charts

Before running OpenCPN on the LiveDVD you should activate the sample data. To do this open a Terminal from the main Applications menu and run "" at the command prompt.

You can download additional US nautical charts from NOAA at 

Setting up your GPS

If you have a GPS connected you will want to start the gpsd service. To do that run:

 sudo dpkg-reconfigure gpsd


 sudo /etc/init.d/gpsd start

BlueTooth GPS users should take special care to read up about the no-probe option. (for this reason we have not started gpsd automatically)

• 'xgps' is a good program to check that Gpsd can see your GPS ok.
