| Gnome Desktop |
This brief tutorial assumes that you have a Raspberry PI with Noobs pre-installed on your SD-Card. Before you do anything make sure that you have Raspian-Lite installed which can easily be chosen from the menu on boot up by holding down shift on your keyboard which brings up the OS selection screen.
To install Raspian-Lite on your SD-Card simply check the abox next to Raspian-Lite in the Noobs menu and click install.
Once installed you will be asked to login with your Raspberry PI username and password, straight out of the box, your username is "PI" and Password is "Raspberry".
Once logged in your will see the command line, enter the following commands:
Get Update: sudo apt-get update
Get Upgrade: sudo apt-get upgrade
Get Distro Upgrade: sudo apt-get dist-upgrade
The first 3 updates are merely a formality but are essential, if there is any updates to install you will be prompted to install and you can safely enter the yes answer.
Next we move to adding the desktop environment, in this case we're going to use Gnome, but not all of Gnome, we're going to do a minimal installation, to add Gnome, we're going to add it's panel and terminal, in the command line enter the following commands:
Gnome Panel: sudo apt-get install gnome-panel
Once the panel has finished installing enter the following commands after each item has installed:
Gnome Terminal: sudo apt-get install gnome-terminal
Synaptic Package Manager: sudo apt-get install synaptic
Package Manager: sudo apt-get install gnome-packagekit
You've now installed a base desktop, you know need to install one more thing, a graphical login manager, to do this enter the following command:
Light DM: sudo apt-get install light dm
You now have everything you need to run a minimal Gnome desktop installation, you can now reboot.
To reboot your Raspberry PI use the following command:
Reboot: sudo reboot
After rebooting you will be presented with a graphical login, enter your username and password and that is it really, it will take a moment to load gnome, not too long and you have a minimal gnome desktop.
Some points to think about, you don't have to install the package kit, it's the same as the synaptic package manager, although to use synaptic only you will need to set a root password which can be done by entering the following command in the terminal:
Root Password: sudo passwd root
you will be prompted to enter a root password which is the administrators password. if you forget the password at anytime, simply enter the command again into the terminal.
Another point to remember is to issue commands with sudo first.
You should have a Gnome Desktop like the picture at the start of the post.
Happy Computing!!
