How to test this distribution ?

This method does not achieve the nominal performance of the system but can be seen in operation without installing anything on your computer. This is also true if you launch the DVD or USB key in session "live" only.


Use of a virtual machine

We recommend that you use the VirtualBox software as it runs on all hardware platforms, and more is Free Software.


  • Features of the virtual machine to test Emmabuntüs :
    • Set 640 MB RAM (1 GB minimum for Emmabuntüs 2)
    • Allocate ( 3 + 1 ) * ISO size for the virtual disk, because the installation of distribution holds 3 * ISO size
    • Take a fixed-size disk, it avoids surprises of lack of space during testing
    • Book quarter of the memory on your graphics card


  • To enable this "hosting" the physical machine (computer) must have at least 2GB of RAM and of course more than ( 3 + 1 ) * ISO size GB free hard disk.


Use in live mode

Distributions Emmabuntüs require at least 1 GB of RAM to run in live mode, otherwise you will get a login screen at launch, and you can not log in due to lack of RAM space to create user data. In order to operate a Emmabuntüs in live mode with less than 1 GB of RAM on your machine, it is necessary to use persistent mode with a virtual disk on USB 1 GB. To use this mode, you must create your USB key for example with Multisystem or USB Creator.


For what type of computers ?

We have already installed our distribution on very different types of machines, including low power to our tests, for example :

  • Netbooks: Asus eeePC 701 (an early model with disk SSD) and 1001PX (one of the latest models but with classic 160 GB HDD)
  • A mini PC with an Intel Atom 410 + 1GB of RAM (in dual boot with Ubuntu)
  • A classic IBM Thinkpad T60 laptop (in dual boot with XP)
  • Different Desktop NEC and HP for years 2005 - 2007

These workstations are used daily in production.


What is the password default distributions ?

The default password is : avenir only applies for installation by the Emmaus communities.


In Live mode or virtual machine under no password password is required. If it is asked is that the machine has less than 1 GB of RAM (eg 512MB). Because of this limitation, Emmabuntüs 2 can not finish its startup RAM. If with 1GB of RAM, the password is requested please report this problem: contact


How to change the default password distributions ?

This is necessary to control the use of computers within the family. By default we create the administrator account with the name "emmabuntus" and the password "avenir", to change the password, please follow the steps below.

We recommend you visit the site Internet without fear (in french), to familiarize yourself with the new information technologies, or to read backgrounder on the desktop of your machine to understand the issues and risks that your children are exposed to a computer. And remember that even if you feel overwhelmed before the computer skills of your children, it is always your parents, and it is you who set the rules of use, and useful lives of the computer within the family circle.

Ubuntu, like all other operating systems family GNU/Linux is an inherently multi-user system. This means that you are not limited to a single user account in the operation of your computer. You can create multiple user accounts for each user of your computer, as well as for various uses.

What is a user account ? this is a collection of parameters relating to a particular profile. These parameters include the details of identity of a user (name, profile photo, etc..), Or the list of user groups which its account is part and many personal data (mailboxes, passwords, preferences of the software used, choice of theme desktop environment, etc..)

Multiply user accounts in a multi-user is a guarantee of safety. Take for example a typical family, two parents and two children. By creating a user account for each individual, it will be possible to set that parents can install new software, but not children, each person can configure their working environment, according to their tastes, needs and moods, each will have its own address book and its mailbox, unmixed with emails from other family members, some sensitive areas of the computer can be put out of reach of children.

To manage the various user accounts, Ubuntu includes the tool users-admin.


Find the tool for managing user accounts :

The tool users-admin is in the menu System → Administration and runs by selecting the menu item Users and Groups.


Ajouter Utilisateurs Groupes.png


Manage your user account :

Parametres Utilisateurs.png

Once the program is executed, the interface opens with a list of user accounts. By default, all user accounts can not be changed, except the current account, since its current session, a user can change settings related to their account only.

Select your own user account in the list and press the Properties to access advanced information. The tasks of modifications you can apply to your own account are limited: you can only change your password. Other administrative tasks on your behalf can be made by administrators.


Change their password :

Modifier mot de passe.png

The utility users-admin allows a user to change his password session. It is this that is used for the opening of the session user.

To change this password:

  1. Press [Edit] which lies to the right of the title Password;
  2. In the new window that opens, enter your current password in the field Current Password;
  3. Then:
  4. * Check the Enter a password manually and manually enter a password of your choice in the box New Password. Repeat the same password in the box Confirmation or
  5. * Check the Generate a random password. A password is randomly generated. Memorize it;
  6. (Optional - Administrator only) Check 'Do not ask for password to login' to allow this account to log on without entering a password. Only an administrator can enable or disable this feature on any account;
  7. Press [Validate] to save your changes.

For more details on the management accounts and user groups, see the full article on the site Ubuntu (in french).


Start default Windows when starting Grub

Open the file /etc/default/grub to it using one of the following lines depending on the file editor included in your distribution:

   gksudo geany /etc/default/grub
   gksudo gedit /etc/default/grub


Change the line GRUB_DEFAUT putting the symbolic name

  GRUB_DEFAUT="Microsoft Windows XP (on /dev/sda1)"


Uncomment the next line to disable the graphical GRUB mode which can cause some problems with older generations of flat screens

   #GRUB_TERMINAL=console


Update the launcher (GRUB)

  sudo update-grub

I can not change the background screen, the default wallpaper is reset after every reboot

In Emmabuntüs 10.04 management offices wallpaper is made by the software Wallpapoz, and make a substantive change to screen following the conventional method of Ubuntu does not work, because on the next reboot, Wallpapoz will overwrite your settings.

To change the wallpaper of a desktop should start Wallpapoz -> Utilities submenu and replace the wallpaper with those desired. Wallpapers classic Ubuntu is in /usr/share/backgrounds.

This operation is not valid for all screens configuration because the startup script test the screen resolution, and depending on it changes the configuration file of Wallpapoz. To apply your new config for all screens resolutions you must copy your file 4 times here: ~/.Wallpapoz be the last change for example wallpapoz_ecran_16_9.xml file must be copied in wallpapoz_ecran_4_3.xml, wallpapoz_ecran_5_4.xml, wallpapoz_ecran_16_10.xml to apply your changes to the four screen sizes.


Tips for using Lemmabuntüs (10.04 LTS)

How to automatically log on Lemmabuntüs ?

  • Open a terminal window: Accessories → LXTerminal
  • Type this line in the terminal, to edit the default file: sudo leafpad /etc/lxdm/default.conf
  • Enter the administrator password
  • Add this line under [base]: = autologin your_login_name

Pysycache from the dock of the Lemmabuntüs don't start

This comes from a poor default configuration of the launcher and patch is available here.

Download the package, then try its execution, then you must restart the machine for the fix effective.


Tips for using Emmabuntüs 2 (12.04 LTS)

The Emmabuntüs 2 contains too many software !!!

This us a very good point is made by many people, this is why we have incorporated in this version 3 profiles dock (Experienced, Beginners, Children) by language. This does not delete any program, but allows for each user profile to have its environment, and may if it wishes to change its Dock without altering the profiles of two other docks.


To change the profile of the Dock :


Click Help, then change the type of Dock


Select your profile dock


Here is an example for the sub menu Office :


Profile Experienced
Profile Beginners
Profile Children


Note : We made this choice to install too much software, because if we had proposed the installation of software to the card, we would have had enormous difficulties to dynamically update the docks, because that would require understanding how it , to sort of reverse engineering on the dock management, and any changes by the team of Cairo-Dock, we would have to redo everything. Given the size of current disks that represents an installation of 10 GB? But you are always free not to use all software in the distribution, and we will keep you no grudge, for that matter, for my part I never use Mr. Potato Head ;-)


See the incomplete list of software 'Emmabuntüs 2.


The management of docks in different languages

The Emmabuntüs 2 contains a set of basic dock for the following languages :

  • French
  • English
  • Spanish
  • Portuguese
  • German
  • Italian
  • Arabic


The dock fits the language of your system, and if you use your system for a language not supported by the Emmabuntüs 2, it will be in English.


How to change language in Emmabuntüs 2 ?

If your language is not supported, you should be in English by default, or if your language is supported partially do the following:


To change the language using the dock, it's easier, go to Help -> Language Support


or menu at the top left -> Setting -> Language Support


If your language is not in the list "Language for menus and Windows", clic on "Install/Remove Languages.."


Scroll the new list, and select your language to install, and click "Apply Changes", on bottom right of the window

Note: If your language is not in the list, do Maintenance -> Update Manager and update, or in a terminal window: sudo apt-get update


Put your password and click "Authenticate" to validate

Note: If the language can not install, update your system, do Maintenance -> Update Manager, and update.


Installation of the new language


Your language should now appear in the bottom list "Language for menus and Windows", select it, and drag it to the top of the list


Click on "Apply System-Wide"


On tab "Regional Formats":


Scroll through the list to select your region language


Click on "Apply System-Wide"


Now you just need to restart for the changes to take effect.


Now the system is in another language


Note : All programs are not managed by the System, and for some of them it is necessary to go to the preferences of the software to change the language. All do not support as many languages ​​as the operating system, but if you think that the software has not your native language should have, then contact the developers and help for translation.

How to Emmabuntüs 2 under LXDE ?

  • For 1.04 and later, follow the procedure below:


Launch from the dock in Expert mode: Utilities → Installation LXDE, or run this command in a terminal:

  /opt/Lxde/install_lxde.sh

Disconnect and reconnect by selecting the LXDE or OpenBox environment in the selector at the bottom left of the login window


  • For versions prior to version 1.04 follow the procedure below:


To change the desktop manager, you must :

   sudo apt-get install-y-qq lxde
  • Disconnect and reconnect by selecting the LXDE environment in the selector at the bottom left of the login window
  • When you restart the Dock Cairo-Dock is the bar management LXDE menus, but just go to the bar and do a right-click of the mouse, then "Preferences panel" and select Position, Edge, Top.


That now you know all about manipulation to ;-)


Emmabuntüs 2 under LXDE


PS: for perfectionists: if you want the stop button on the bottom right at the dock, you must install :

   sudo apt-get install-y-qq lubuntu-default-settings


then put lubuntu-logout instead of xfce4-session-logout in control of the stop button (right-click and Edit), but it is only applied to the current profile at the Dock, so if you profile must change it again !


After installing Emmabuntüs a package is broken, and it blocks the updates or installations

Sometimes a packet is broken at the end of the installation : it is often a codec pack Adobe Flash.

This is due to the activation of packages third (fluendo mp3) during installation it is preferable to do not check, as they will be installed at the discretion of the users in the first restart the computer.

To resolve this deadlock, you must:

  • Go to Synaptic (the mouse icon on the top left -> System -> Synaptic Package Manager or in a terminal window type synaptic)
  • Make fix broken packages (Edit -> Fix broken packages)
  • Reload deposits (circular arrow left under File)
  • Select two packages to complete removal Flash (Search: magnifying glass to "flash", then select the package and click Remove right complete)
  • Reinstall (Select the packages and click Install right)


Synaptic Package Manager


After these manipulations few warmup, everything should return to normal, but if your browser due to this does not always visualize videos in Flash format, use the following solution: "I can not view videos in Flash format".


Blocking when updating the distribution because issue.net and lsb-release files

In the last updates of August 2012, a deadlock occurs when replacing a file where issue.net or lsb-release, despite the authorization by the user to override where to keep those files.

To fix that make a computer restart and retry the update, then when applying the system to replace these files, accept the replacement thereof, and everything should get sorted.


Note : These two files serve only to inform the version of the distribution, and does not affect system operation.


The drag/drop into the Multisystem window does not work

This anomaly comes from GTK who is unable to support drag/drop Xubuntu. To get to use Multisystem, here are two ways to add an ISO file on the USB :

  • Right-click -> Copy your ISO file, and in the area of drag/drop Multisystem, use CTRL+V, then press "ENTER".
  • Use multi-selection interface, and double click on your ISO file, then click the Create button (big green button at the bottom right)


The Dock of the distribution is double

This may arise from the use of backup mode session, we do not recommend using. To find a healthy situation, please turn it off, but this does not solve the problem because cache backup session is not emptied. To clean the following command :

  rm -r ~/.cache/sessions/*


Dock Emmabuntüs distribution was replaced by Cairo-Dock

If you have a dock like this :


Cairo-Dock original version


instead of the usual dock below :


Cairo-Dock Emmabuntüs version


To retrieve the version Emmabuntüs dock, it's pretty simple : go to the home directory and then display hidden files (press Ctrl + H for non-specialists) and go to the directory .Config. In this directory you should find link the name of "cairo-dock". If instead you have a directory "cairo-dock" must rename it (right click of the mouse on the folder "Cairo-dock" and rename eg "cairo-dock-old" (do not delete it as you can return to the previous situation, besides our launcher does not remove and do not point the dock Emmabuntüs because of it) and reboot, and everything should return to normal.


Rename the Cairo-Dock


AutoPlay CD/DVD does not work

If the Audio CD and DVD are not automounted, it comes from a misconfiguration on the launch of the media.

To correct this problem, click on Utilities in the dock, then Settings -> Disk and removable media, and the Multimedia tab.

In this panel you must place the following commands:


Settings launch CD/DVD Removable


  • Audio CD: /usr/bin/audacious -E cdda://

If you prefer smplayer or VLC commands here:

  • /usr/bin/smplayer cdda://
  • /usr/bin/vlc --playlist-autostart cdda://


  • DVD-Video: /usr/bin/smplayer dvd://

If you prefer VLC the command is: /usr/bin/vlc --playlist-autostart dvd://


My WIFI card no longer works in Emmabuntüs 2

Notebooks with Broadcom cards (mainly HP and Dell) using the free driver "Broadcom 802.11 Linux STA wireless driver" does not work on Emmabuntus 2, although it is proposed automatically.

Relevant cards: Broadcom's BCM4311-, BCM4312-, BCM4313-, BCM4321-, BCM4322-, BCM43224-, and BCM43225-, BCM43227-and BCM43228-basedhardware.


It is therefore not to download and install a new one, we have successfully tested the extractor b43 firmware.

Must first identify the card as there are at least 3 sets corresponding to 3 different installers:

  • Firmware-b43-installer: BCM4306/3 BCM4311, BCM4312, BCM4318
  • Firmware-b43-installer-lpphy: BCM4312 (with Low Power aka LP-PHY)
  • Firmware-b43legacy-installer: BCM4301, BCM4303, BCM4306/2


These three packages are used to download a firmware supplied by Broadcom owner.

These packages depend on all 3 of b43-fwcutter, which is used to extract the firmware from the downloaded archive and install on the system.


ID: type the command in a terminal: lspci | grep Network


  • If the return is for example:

02:00.0 Network controller: Broadcom Corporation BCM4311 802.11a/b/g (rev 02)

Install (only the installation command line worked in our case)

sudo apt-get update
sudo apt-get install firmware-b43-installer

Answer yes (Enter) during extraction and restart the PC at the end.


  • If the return is:

01:00.0 Network controller: Broadcom Corporation BCM4312 802.11b / g LP-PHY (rev 01)

Install:

sudo apt-get update
sudo apt-get install firmware-b43-installer-lpphy


  • If the WIFI does not work try the following commands in a terminal window:
sudo apt-get remove bcmwl-kernel-source (remove competitor wl driver)
sudo rmmod b43
sudo rfkill unblock all
sudo modprobe b43 (b43 reinstalls)
sudo rmmod b43 (b43 temporarily remove)
sudo rmmod wl
sudo rmmod BCMA (removes the drivers and competitors wl BCMA)
sudo modprobe b43 (b43 reinstalls)
gksudo gedit /etc/modprobe.d/blacklist.conf

Add at the end of the file that has just opened in "root": blacklist BCMA (BCMA competitor blacklist the driver)


  • For a permanent solution, edit the file "/etc/modules" by adding the line "b43"

Example:

sudo nano /etc/modules (opening nano in"root" also works with gedit)


I can not see the video in Flash format

This may be due to an incompatibility between the new version of Adobe Flash Player, and your hardware. We recommend that you install Flash player version provided by the Linux-Mint, and available in Emmabuntüs 2, under Maintenance -> Software Not Free -> Linux-Mint Flash


I can view Flash videos, but they are choppy

This behavior may indicate a power problem on your machine, you should use the application Minitube to view the videos of Youtube. To install this application please run the following commands in an xterm, under Maintenance -> Terminal Emulator :

  sudo add-apt-repository ppa:ferramroberto/minitube && sudo apt-get update -qq && sudo apt-get install -y -qq minitube
