After installing from NOOBS for the first time, it will run raspi-config automatically.
To save time later, I choose to change the hostname,
enable the pi camera, enable I2C and enable SPI and install SSH.
Then, it will reboot and you can log in with the username pi and the password raspberry.
You can use raspi-config to do this, or do it manually:
|( note: you will be asked to enter your existing password, and your new password twice. The passwords will not appear on the screen. )|
The first thing you will need is internet access in order to update your pi. Once logged in as pi, run startx to run the GUI.
You will notice that the menu bar, which traditionally is at the bottom of the screen, is at the top. To move it to the bottom, right-click on the menu bar, choose 'Panel Settings' and move the menu bar anywhere you wish.
Raspbian comes with a basic internet connection package, run it from Menu -> Preferences -> Wifi Configuration.
You will need to know your network name and of course the password.
Click on the 'manage networks' tab, and scan for your network, then double-click this to configure it.
The 'status' tab should now say "connected".
The first thing we should do is update the Pi with the latest versions of all the packages, and install
a more user-friendly package than apt-get. This will test the internet connection, look
at the command prompt, download the list of latest packages (30,000+) and generally be a good start.
If you haven't done this yet, then see this page.
The next thing I choose to do is ensure I have a fully working computer - it should play all types of media, and handle images. I've created a list of recommended packages to achieve this.
