5 Mistakes Are Often Made By The Ubuntu User (newbie)

Many mistakes are often made for beginner ubuntu user, but which I quote here is the biggest mistake that is often done by the user both in terms of fundamentals and a very complicated, here are five of the biggest mistakes often made by the user:

1.  Too quick surrender

Many of us may never experience this. Assume Linux is difficult to learn and use, so only use it within a few hours only to give up and immediately thought back to using Windows. Could be due to normal, that's a wise sentence that invites us to get things in order.
 

2.  Avoiding terminal

Do not be shy and lazy to learn the command line in Linux, because once we know the 'miracle' command line we will be more comfortable using Linux. This is where a lot going on, new users shy and lazy to use the command line and prefer a graphical command.

3.  Sending OpenOffice document to Microsoft Office users in the default format

This happens because many new users in Linux they think the documents created and saved by default using OpenOffice can be automatically opened by a user of Microsoft Office. If there are cases like that then do not save it by default, but use the Save As (Save As) and choose the document formats for Microsoft Office (. Doc or. Xls).

4.  Delaying updates
 
The mistake was not only done by new users only, but the old user and admin classmates too much to delay the update. Whereas with a regular update the Linux system we will ensure a safer system.

5.  Login to the system as root

Do not log into the system as root, but as a normal user login and use the root account only when really needed it.
