Starting slide Welcome to this spoken tutorial on Ubuntu Desktop.


Using this tutorial, we will get familiar with the Ubuntu Desktop on the gnome environment.


For this purpose, I am using Ubuntu 10.10.

Goto desktop What you are seeing now, is the Ubuntu Desktop.
Move the mouse to the main menu You can see the main menu on the top left hand side corner.

To save it, I can press Clt+s or goto File and then click on save.

Click on File->save So let me go to File and then save.
“Save as” dialog comes up Now a small dialog box comes up.


It asks for filename and location in which the file has to be saved.

Type “hello.txt” as file name. Select Desktop as location. Then click on. So let me type the name as "hello.txt" and for location I select it as Desktop and click on save button.
