This section contains any information which will be of assistance in following the rest of the guide.

使用终端/ terminal / shell

All of the above refer to the same thing - a command line interface which can be used for controlling the system as an alternative to using the graphical user interface. Many of the tasks within the guide can be performed using the GUI, but it is often simpler for the purposes of explanation to use the command line to get things 'up and running'.

To open the console, navigate to: Applications --> Accessories --> Terminal - and a window will open into which you can type.

Any command prefixed by 'sudo' is given administrative (or root) access, and as such, you will be prompted for your password.

检视一个程序或命令的帮助 - 手册页

Most programs and commands come with their manpages, a manual for advisory.

You may check what a command does by typing in terminal, for example:

   man apt-get


   man gedit

It is very usefull to know what a command does before we execute it.


It is important to have the system updated, so that we have all the latest patches, security fixes and packages upgrades from the repositories.

First, we navigate to:

  System --> Administration --> Software Sources

and check that all repositories are enabled.

Then, we open the terminal:

  Applications --> Accessories --> Terminal

and type:

  sudo apt-get update

The system will ask as for your password. You may NOT see the password displayed (security issues), but the system recognises that you are actually typing it.

  sudo apt-get upgrade
  sudo apt-get dist-upgrade

And we have finished.


In Ubuntu there are two ways to install packages into your system.

You can install packages through the Terminal or the Synaptic Package Manager

A.如何使用APT安装软件包 - 终端方式

Go to

 System --> Accessories --> Terminal 

Apt is the Debian Package Manager and is being used in Ubuntu as well.

Now, we may install a package by typing:

 sudo apt-get install package

for example, Amarok, the music player:

 sudo apt-get install amarok

It is very simple as you can see.

Sometimes we may need to remove a package.

We type:

 sudo apt-get remove package

If we want to remove exaile music player, we type:

 sudo apt-get remove exaile

Apt checks the dependencies of a program automatically when we install or remove them.

B. 如何用新立得安装软件包 - 简单的GUI方式

You may navigate to:

 System --> Administration --> Synaptic Package Manager

There you may install whatever package you want by simply making a search, by pressing the Search Button.

There you have a list of packages with an empty box in the left. You click it and it is entered into the queue for the installation.

Then you press "Apply" and Synaptic installs the packages by calcuting the dependencies first.


There are four ways to find a package in the repositories. All of them quite easy to execute.

A. 如何在新立得中搜索软件包

Open Synaptic

  System --> Administration --> Synaptic Package Manager

and press the Search button. There you have a empty space to complete so that Synaptic makes the research.


Open your favorite web browser and navigate to


You are interested in a. http://packages.ubuntu.com/hardy/ , b.http://packages.ubuntu.com/hardy-updates/ , c.http://packages.ubuntu.com/hardy-backports/ , d.http://packages.ubuntu.com/hardy-backports/main/newpkg

C. 如何用APT搜索软件包

Open a terminal

 Applications --> Accessories --> Terminal

If you want to search for a program named, for example, "pack-age" you type

  sudo apt-cache search pack-age

As in Synaptic, which uses apt-cache search in a graphical way, you may find other packages that have the words you entered.

If you want to search for a music player type

  sudo apt-cache search music player

D. 如何用Aptitude搜索软件包

Aptitude is a the "terminal alter-ego of Synaptic". There is a "Search" option in the Menu Bar on the top . You may click it or navigate there with the keyboard.


Fortunately this has been easy to resolve since Gnome 2.12

You can right click on the menus on the top left of the screen and edit their content.

In case there is a problem, open a terminal window, and type:


From here you can edit the menus at the top of the screen, and add new items to get access to your new application (presuming you can discover where it was installed). If you're having trouble, try:

  locate applicationame

Which should throw out some possible locations.



There are three available methods - the first ensures you are always running the latest version of the drivers, and the second is marginally simpler. The third one is an alternative method for those that have older ATi GPU installed. The last one is for those that own the latest ATi cards (2xxx and 3xxx generations) and can't have appropriate display with the latest ATi drivers (via EnvyNG) or with the repository driver.

A. 用EnvyNG安装最新版本驱动(ATi & nVidia)

Read first this faq: http://albertomilone.com/envyngfaq.html#A

Open a terminal and type :

 sudo apt-get install envyng-gtk

After rebooting, drivers should be installed and working.

B. 受限驱动管理器安装(ATi & nVidia)

Navigate to:

 System --> Administration --> Hardware Drivers

and there you'll see your Graphics Card and an option for installation of its drivers.

Choose it and the press "Apply". It shall install the repository driver - a reboot may be required.

(Applicable for both ATi/AMD and nVidia)

C. ATi开源radeon驱动(仅ATi)

Navigate to https://help.ubuntu.com/community/RadeonDriver

for more instructions.

D. RadeonHD驱动(仅ATi)

Check with Synaptic Package Manager for



Always make sure that you don't have another ATi driver installed.

Install the nVidia graphics control panel:

  sudo apt-get install nvidia-settings

And then run the configuration utility:

  sudo nvidia-settings

You should be able to configure all your monitors, set them to seperate resolutions, and change their positioning relative to one another. When you are finished, make sure you click 'Save to X Configuration File'. It is possible that you may have problems with the boundries of monitors; logging off and back on again should resolve this.



Open a terminal and type :

 sudo -s -H

and then enter your user password.

After that :

 apt-get update
 apt-get upgrade

To be upgraded. Please check that you have all repositories enabled in Software sources.

Then these commands :

 apt-get install gstreamer0.10-plugins-ugly-multiverse gstreamer0.10-plugins-bad-multiverse 
 gstreamer0.10-plugins-bad gstreamer0.10-plugins-ugly gstreamer0.10-ffmpeg libxine1-ffmpeg libdvdread3

Now you have the most of the codecs needed to play most of multimedia you may own.

安装DVD 支持

At the console, type:

  sudo gedit /etc/apt/sources.list

Αnd paste in the end of the file the below:

  ## Medibuntu - Ubuntu 8.04 "hardy" 
  ## Please report any bug on https://bugs.launchpad.net/medibuntu/ 
  deb http://packages.medibuntu.org/ hardy free non-free

save the document and then in the terminal type:

  wget -q http://packages.medibuntu.org/medibuntu-key.gpg -O- | sudo apt-key add -

in order to receive the appropriate key.

Finally, at the terminal, type:

   apt-get update 
   apt-get install libdvdcss2


On Xubuntu, you may experience some glitches with Pulseaudio like no sound at all after upgrading from Gutsy. The reason may be that the Pulseaudio daemon is not started. Take note that the sound server is not started at boot time (to reduce the risk of inter-user audio corruption), but at login time. So, you will have to add an entry to your autostarted applications for Pulseaudio. Here is an example:

:[Desktop Entry]


At the console, type:

  sudo apt-get install vlc

To remove,

sudo apt-get --purge autoremove vlc

If you encounter sound problems (due to PulseAudio ), type:

   sudo apt-get install vlc-plugin-pulse

and choose PulseAudio as output in VLC options.


Totem is the default program for DVD-playback in Hardy, and the is no obvious way to change it. A lot of tips that worked in previous versions no longer work. The main problem is that VLC does not register itself as a DVD-capable application.

At the console, type:

   cp /usr/share/applications/vlc.desktop /home/hildenae/.local/share/applications/vlc-dvd.desktop

edit the file

   gedit ~/.local/share/applications/vlc-dvd.desktop

replace the line

   Exec=vlc %U

with either

1. (all you really need)
   Exec=vlc %f
2. (recommended settings from ubuntuforums for better dvd playback)
   Exec=vlc --vout-filter deinterlace --deinterlace-mode blend --volume 512 %f
3. (recommended settings from ubuntuforums for better dvd playback and automatic full screen playback)
   Exec=vlc --vout-filter deinterlace --deinterlace-mode blend --volume 512 --fullscreen %f

Save the file and close gedit. At the console, type:

   gedit ~/.local/share/applications/mimeapps.list

make the line «x-content/video-dvd=» under [Added Associations] read:

   [Added Associations]

Open Nautilus (default file manager), and navigate to Edit->Preferences>Media>DVD Video and select VLC media player (you should be able to choose between Totem and VLC)


Whilst Amarok is a KDE/Qt application, it will work fine on Ubuntu, and can be installed by typing:

  sudo apt-get install amarok


Exaile is a GTK, Amarok-like Music Player and it is very easy to install. In terminal, type:

  sudo apt-get install exaile

Make sure you have the appropriate multimedia codecs installed.


This will install pulseaudio utilities such as individual application volume controls and audio server tools.

Open a Terminal window and type the following:

  sudo apt-get install libasound2-plugins "pulseaudio-*" paman padevchooser paprefs pavucontrol pavumeter libflashsupport

Run Pulseaudio Device Manager from the Applications > Sound and Video menu to access the tools.



LAMP stands for Linux, Apache, MSQL and PHP. You can install an integrated package that includes all four from the Synaptic Package manager (if you are using a Desktop Edition).

System-->Administration-->Synaptic Package Manager-->
Edit-->Mark Packages by Task-->LAMP server -->Apply


This will install Apache2, PHP5, MySql5, and PHPMyAdmin.

Firstly, type the following command at the console:

  sudo apt-get install apache2 php5 mysql-server-5.0 phpmyadmin

This will install all the necessary applications. You may be prompted to decide on a MySQL root password (set one if you want), and to configure PHPMyAdmin (select apache2 as the server type). After this is complete, we need to perform some minor configuration to get PHPMyAdmin working. Type:

  sudo gedit /etc/apache2/apache2.conf

Scroll right to the bottom of the file that opens, and add:

  # Enable PHPMyAdmin
  Include /etc/phpmyadmin/apache.conf

Now save, exit, and type:

  sudo /etc/init.d/apache2 restart

Everything should now be configured - go to for webpages, and for database administration. The webroot is located in /var/www/ by default. This is not particularly useful, as we do not have write access to this directory. Fortunately, this is easy to solve, by...


This allows us to access a different folder as our webroot from a different address in our browser - face it, 'localhost' or is boring.

Start by adding a new host. This is easy to do via System --> Administration --> Network; click on the Hosts tab, select the localhost item from the list and click properties. You may need to click the 'Unlock' button and enter your password first. Underneath the entry 'localhost', on a new line, add your entry of choice; for example, we'll use 'testhost'. Add this, and close all the dialogs.

Now we need to edit a configuration file, so type into the console:

  sudo gedit /etc/apache2/httpd.conf

In the resulting file (which may well be empty), add the definition for your host! My username is 'dan', and I want my webpages to be served from a directory named 'www' in my home, so I would add:

  <VirtualHost *>
     ServerName testhost
     DocumentRoot /home/dan/www

I can now add files to /home/dan/www, and access them by visiting http://testhost



Linux MCE

LinuxMCE is an integrated home theater/home security/home automation/telephone PBX/intercom system for your home. It is a community project that is a fork of the Linux Pluto commercial endeavour. There is a version that runs on Kubuntu 7.04 (Feisty) and a version for Kubuntu 7.10 (Gutsy). A version for Kubuntu 8.04 (Hardy) is due out soon. It is available in 32 and 64 bit versions. LinuxMCE can run either as a standalone Home Theater PC or can co-ordinate a fully networked home, using the networking capabilities that are intrinsically part of the Kubuntu Linux OS. For more info see the LinuxMCE website.

LinuxMCE can be installed at the same time as the Kubuntu OS, on a new PC with an Nvidia graphics card (6000, 7000, or 8000 series), from a single DVD.

LinuxMCE can also be installed as an add-on package to an existing Kubuntu system, using the LinuxMCE 2 CD installation. You will need a Kubuntu LiveCD for your installation, even if you already have a full Kubuntu installation in place. (The LinuxMCE installation uses the Kubuntu LiveCD for additional modules.) Note that the LinuxMCE version must match the Kubuntu version -- i.e. the LinuxMCE 710 version CDs require the Kubuntu 7.10 (Gutsy) Live CD.

With the 2 CD installation, it is possible to run Kubuntu separately from LinuxMCE on the same PC, but it is recommended to dedicate at least one PC to LinuxMCE as a Core server.

LinuxMCE incorporates MythTV, Pluto home automation, Motion security surveillance, Asterisk PBX, VDR video disk recorder, and other home automation/security/theater packages in an integrated platform.

At this time, the automatic installer for Linux MCE uses the KDE desktop (Kubuntu). There are users that have made Linux MCE work with the Gnome desktop (Ubuntu) and other Linux distributions, but it is recommended to stick with the Kubuntu OS, as required by the LinuxMCE automatic installation.

PVR (Personal Video Recorder)


Mythbuntu is an Ubuntu-based derivative (based on the Xubuntu (XFCE) desktop) that is meant to function as a standalone PVR, based on MythTV. It can be used, however, with a Gnome (Ubuntu), KDE (Kubuntu) or XFCE (Xubuntu) desktop, which can be added at any later time.



Zoneminder manages surveillance cameras and stores images on the hard disk. Images can be viewed using a (LAMP) server remotely. X10 devices can be triggered using built-in perl scripts. For more info see the Zoneminder website.

There is a Zoneminder package for Hardy (that was the package from Gutsy). You should be able to install the package from Synaptic Package Manager.

However, if that does not work, try the instructions that worked for Feisty:

  • You must have the LAMP server installed. In addition, you will need additional modules:
sudo apt-get install ffmpeg libarchive-tar-perl libarchive-zip-perl libdate-manip-perl libdevice-serialport-perl
sudo apt-get install libjpeg62 libmime-perl libstdc++6 libunwind7 libwww-perl zlib1g
  • Download the .deb package from the package manager's website:


  • Install using the Debian package manager. (No other method seems to work.)
dpkg -i zoneminder_1.22.3-8_i386.deb
  • (Note: If some dependencies are still unsatisfied, make sure you have these packages installed):
sudo apt-get install libc6 libc6.1 libgcc1 libgcc4 libstdc++6
(These should already be installed as part of the LAMP installation):
sudo apt-get install apache2-mpm-prefork libapache2-mod-php5 libmysqlclient15off mysql-client mysql-server php5  php5-mysql

If your installation is successful, you will now need to set up the configuration files and databases for Zoneminder.

  • Copy the configuration file and restart the Apache2 server.
sudo ln -s /etc/zm/apache.conf /etc/apache2/conf.d/zoneminder.conf
sudo /etc/init.d/apache2 reload
  • View Zoneminder from your web browser:
  • Set up a MySQL database for Zoneminder
If this is the first time you have used MySQL, the default global MySQL superuser root will not have a password. You should set one now. Instructions for setting mySQL initial privileges are here.
In short:
mysql -u root
mysql> UPDATE mysql.user SET Password=PASSWORD('your_new_password') WHERE User='root';
mysql> quit
In addition, you can set up an additional global MySQL user (such as mysql_user, for example) by following the instructions here. That way you can reserve root login for emergencies.
In short:
mysql -u root
mysql> CREATE USER 'mysql_user'@'localhost' IDENTIFIED BY 'mysql_user_passwd';
mysql> quit

Now you must create a MySQL database for use by Zoneminder. This is an administrative MySQL command, so you must use one of your global MySQL users (either root or mysql_user, as created in the example above). You can name your Zoneminder database anything you want, instead of zmdatabase.

mysqladmin -u root -p CREATE zmdatabase


mysqladmin -u mysql_user -p CREATE zmdatabase

Create users for the Zoneminder database. As always, I create a root user for emergency use. I use the same password for root as I do elsewhere on my system. Then I also create a user named zm_user (but you could also creat a user named mysql_user, to keep everything consistent). [I use a unique user here because this is a home security system, after all, and I don't want it breached.] These users are specific to this database; they can be the same users as used elsewhere in the system or can be unique users.

mysql> GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER, CREATE TEMPORARY TABLES, LOCK TABLES ON zmdatabase.* TO 'root'@'localhost' IDENTIFIED BY 'password'; (I used my usual root password here).
mysql> quit
mysqladmin reload

Note: mysql commands (i.e. any entered at the mysql> prompt) must end with a semicolon. If you forget the semicolon, nothing will happen.

Myth Zoneminder

MythZoneminder allows you to view your security cameras through Myth TV, essentially. It is a plugin that interfaces the two packages Zoneminder (which must be working on your system) and Myth TV (which must also be working.) It can be found in Synpatic Package Manager as the mythzoneminder package.

See the installation instructions.

如何用Ubuntu Live CD恢复GRUB到启动分区或MBR

Sometimes, if an Ubuntu installation goes wrong, or a Windows NT bootloader overwrites MBR and doesn't recognise the Linux installation, we have to restore our GRUB bootloader that is, generally, very flexible.

First of all, we burn a Hardy Heron (Ubuntu 8.04) ISO (on a CD(R , RW) or DVD (+R , +RW)) or make sure that we have one already.

Then, we change, in the BIOS, the boot load sequence and we put the CD/DVD option first.

After that, we boot the Live CD, we choose the first option and in a few minutes we have arrived at the Live CD Desktop.

So, we go :

 Applications --> Accessories --> Terminal 

Then, we have to remember which is our Ubuntu installation partition.

In our example, it is the second one (/dev/sda2), formatted as ext3, in the first HDD of a SATA controller. We suppose that it is the second one, since, in case we have Windows that demand to be in the first partition (/dev/sda1), this one is occupied.

Now, you have to be really careful. You have to enter the right partition, instead of sda2 (unless it is the same) In the terminal :

  cd /
  sudo -s -H
  mount -t ext3 /dev/sda2 /mnt
  mount -t proc proc /mnt/proc
  mount -t sysfs sys /mnt/sys
  mount -o bind /dev /mnt/dev
  chroot /mnt  /bin/bash

And now, you are actually "running" Ubuntu within the Hard Drive but through Live CD's terminal.

Now we restore GRUB like that:

1) Restoration to MBR

  grub-install /dev/sda

2) Restoration to partition (example: /dev/sda2)

  grub-install /dev/sda2

In the first case (that is the most usual) you have certainly installed GRUB on MBR after you receive, in the terminal, the message that there are no errors.

After you reboot, you have your favorite bootloader restored.


First step is to backup all necessary data, if something goes wrong your data will be lost in the process if it's not backed up. Also note that your home folder needs to be located on a separate partition than your root partition, if not see #How to make partitions.

Second, install necessary software:

  sudo apt-get install cryptsetup

Insert the new module, dm-crypt into the kernel:

  sudo modprobe dm-crypt

Check to see what encryption schemes are available:

  cat /proc/crypto

If only MD5 is listed, try inserting the appropriate modules into the kernel:

  sudo modprobe serpent

Above is an example, this could also be twofish, blowfish or anything other crypto module that you would like to use.

The following commands will assume that your home partition is /dev/sda1, please change it to match your own configuration.

Next step we use cryptsetup to change the partition with the luksFormat option, this command will cause you to lose all data on /dev/sda1.

  sudo cryptsetup luksFormat -c algorithm -y -s size /dev/sda1

Where algorithm is the algorithm that you chose above such as serpent aes, etc.

Size is the key size for encryption, this is generally 128 or 256. Without specifying the algorithm or the size, I believe it defaults to AES 256, more information and additional options can be found by reading the man page. The above step will ask you to choose a password and verify it. Do not forget this password.

We can then use the luksOpen option to open the encrypted drive.

  sudo cryptsetup luksOpen /dev/sda1 home

Home is a nickname which cryptsetup uses to refer to /dev/sda1. It also creates the device /dev/mapper/home, this is what you would actually mount to access the filesystem. If you specify another name other than home, it will create the device /dev/mapper/[name], where [name] is the nickname that cryptsetup will use. This step will ask you for your LUKS passphrase, this is the password you created in the previous step.

Next, we create the actual filesystem on the device. I use reiserfs, but it could just as well be ext3.

  sudo mkreiserfs /dev/mapper/home


  sudo mkfs.ext3 /dev/mapper/home

Next step is to mount your encrypted device and copy your files back to your home directory.

  mkdir new_home
  sudo mount /dev/mapper/home new_home
  cp -r * new_home

Now we have to set up everything so that it's ready to go at boot, we need to tell the system that there are encrypted disks that we want mounted.

  gksudo gedit /etc/crypttab

Enter the following as one line at the end of the file.

  home       /dev/sda1       none       luks,tries=3

remember home can be any name that you want, just remember that this maps to /dev/mapper/[name]. The option tries=3 allows 3 tries before a reboot is required or the disk is not decrypted.

Next enter the device info in fstab that we want to mount on boot.

  gksudo gedit /etc/fstab

Enter the information as one line at the end of the file.

  /dev/mapper/home       /home       reiserfs       defaults       0       0

Remember to substitute /dev/mapper/home with your device /dev/mapper/[name], /home is the mount point, since this is our home directory, reiserfs is the filesystem type, put ext3 if you formatted it as ext3. For now the default options should be good, change this if you need/require something else. Also, now is a good time to remove the old /dev/sda1 device entry so that fstab doesn't try to load it at boot. This can be accomplished by commenting out the /dev/sda1 line or deleting it.

Final step is to make sure that the proper modules are loaded at boot time.

  gksudo gedit /etc/modules

Now add dm-crypt and the crypto module that you used earlier, such as serpent, aes, etc. Each needs to be on its own line.


That should be it, all that's required is a reboot. During the reboot process, the computer will say "Starting early crypto disks" and ask for your passphrase. If the passphrase is accepted, it will unlock the encrypted partition and mount it on your specified mount point.


You can change the way you enter a command in order to be executed by entering an alias.

For example, you may enter in a terminal "update-system" (a command that in face doesn't exists) that replaces "sudo apt-get update". You can do the same thing for other commands.

This is what you do. Our example is going to be the alias of the command

 ls -FCal --color=auto

that shows with colours and many details the contents of a folder.

Open a terminal

  Applications --> Accessories --> Terminal

and enter

  gedit ~/.bashrc

Be carefull now. Don't erase anything there.

Now, go to the end of the document and enter

  alias ll="ls -FCal --color=auto"

As you can see, now with the command


whenever we want, we call, in fact, this one

  ls -FCal --color=auto

You can do the same thing for other commands that need a lot of switches.

Save the document, close the terminal and reopen it. You may now check your new alias.



Originally a brownish color to match the Ubuntu theme, it does not quite fit with other themes and might want to be changed. Enter the gdm.conf file (sudo gedit /etc/gdm/gdm.conf). About two-thirds of the way down you will see the lines:


Change it to what you like. For all black, use:



The default size of the Terminal window is around 80 columns wide and 24 columns high. To alter this, edit the file /usr/share/vte/termcap/xterm. You can use the following command:

 sudo gedit /usr/share/vte/termcap/xterm

Just a few lines from the top will be the line reading:


Change the number right after co# to change the width. Change the number right after li# to change the height.


It is very easy to make partitions with Ubuntu .

Open a terminal and type:

  sudo apt-get install gparted

Then navigate to

  System --> Administration --> Partition Editor

Then gParted is going to check for your disks and partitions.

There you can modify your partitions but on those that are NOT on the System.

More info :

2) How to separate your /home partition in Ubuntu --> http://www.psychocats.net/ubuntu/separatehome

如何启用Compiz Fusion

In Ubuntu Hardy Heron, Compiz Fusion is already installed and is automatically enabled after you have installed your graphics' card drivers.

The only thing you have to do is to install the Compiz Configuration Settings Manager.

Open a terminal and type:

   sudo apt-get install compizconfig-settings-manager

and it shall be installed. After that navigate to:

   System --> Preferences --> Advanced Desktop Effects Settings

and there you may enable/disable any plugin you want.
