Introduction to Linux - A Hands on Guide

This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Hi! I have a problem. I have xfce and my display resolution is 1920:1080 but I'm not sure the display ( monitor tv 32'') ratio is 16:9, because the image is a little bigger than the display. How can i do for adjust the resolution? thank you.

in any case xfce should have a utility to set up monitors; maybe you have to set them up to be side-by-side, and not on top of each other.
i'm not sure; the way you describe your problem it could be different things. maybe emerson is right.

Thank you everybody . I'm trying to correctly set the screen. I use the xrandr command but I don't understand the meaning of the numbers after --transform option.

--transform a,b,c,d,e,f,g,h,i
Specifies a transformation matrix to apply on the output. Automatically a
bilinear filter is selected. The mathematical form corresponds to:
a b c
d e f
g h i
The transformation is based on homogeneous coordinates. The matrix multi‐
plied by the coordinate vector of a pixel of the output gives the trans‐
formed coordinate vector of a pixel in the graphic buffer. More precisely,
the vector (x y) of the output pixel is extended to 3 values (x y w), with
1 as the w coordinate and multiplied against the matrix. The final device
coordinates of the pixel are then calculated with the so-called homogenic
division by the transformed w coordinate. In other words, the device coor‐
dinates (x' y') of the transformed pixel are:
x' = (ax + by + c) / w' and
y' = (dx + ey + f) / w' ,
with w' = (gx + hy + i) .
Typically, a and e corresponds to the scaling on the X and Y axes, c and f
corresponds to the translation on those axes, and g, h, and i are respec‐
tively 0, 0 and 1. The matrix can also be used to express more complex
transformations such as keystone correction, or rotation. For a rotation
of an angle T, this formula can be used:
cos T -sin T 0
sin T cos T 0
0 0 1
As a special argument, instead of passing a matrix, one can pass the string
none, in which case the default values are used (a unit matrix without fil‐
ter).

neither do i, sorry.

i suggest you search the web for more suitable instructions.
