User Accounts and concept

Each Labdoo laptop comes with pre-installed Ubuntu operating system (release names: xx.04 LTS; xx = 2018, 2020 etc.) and 3 users are created, ready to use:

  • student: is a standard user account for students. User student is not administrator, just standard user. The password is labdoo (You can decide to change the current password or not.)
  • guest: is an account which doesn’t require a password to log in. All data will be automatically erased after the user log off from this account
  • labdoo: has super user rights / is administrator! labdoo is an administrator account and has all the access right on the computer. Working under this account without a proper knowledge may crash the system! Therefore, it is recommended to have only teachers know the password of the user labdoo. The password is labdooadmin.

The letters of the password should match with the character-set of the keyboard (latin letters and what you see on keyboard). Using others, non-latin characters might lock you out of the computer.

Important: The keyboard layout can be changed manually at the time of log-in (see below). The system setting of the keyboard layout can be changed via the system file / etc / default / keyboard. Labdoo recommends storing the keyboard layout of the delivered computer in this system file (WYSIWYG).

Important: the keyboard layout, being used when loggin in, will be set during the installation process of (L)Ubuntu. If you installed a computer using images for cloning this will be the German keyboard (DE). Otherwise the keyboard layout using to install (L)Ubuntu. To change the layout after logging in open a terminal (press Strg/CTL + Alt + T at the same time) and type sudo nano /etc/default/keyboard (press Enter), next change the keyboard code, e.g. into EN for English, FR for French, ES for Spanish etc.), optional you can add a country specific code in the next line between the 2 quotation marks (z.B. CH for Switzerland), then store the file (Strg/CTL + Alt + O (Enter), next Strg/CTL + Alt + X).You will NOT modify the keyboard layout being used after logging in. This can be changed using the setting or the keyboard layout icon in the upper task bar (MATE) or lower task bar (LXDE).

Desktops MATE or LXDE

Two desktops are pre-installed on most Labdoo laptopst - MATE and LXDE.

 MATE Desktop is the recommended desktop, but he needs more resources (hardware requirements) than LXDE. If your computer becomes slow try out LXDE. You can switch when logging in.
 LXDE asks for less hardware resources and runs fast even on older hardware.

The computer remembers for each user, which desktop this user used last time and will start this desktop. If you want to change to another desktop you have to switch before logging in. The recommended desktops are Lubuntu (LXDE) and MATE session.

 MATE desktop
 LXDE desktop

To change the password → System Tools → users and groups → +Add (to add a new user) or change → password „labdoo“ → change it → ok

Manage Groups → to group users (e.g. group labdoo)

To Start a Program

There are many useful, fun and educational software and games installed. To start a program:

Click on the lower left corner on the Lubuntu icon (similar to Windows XP) → “Education” or "game“ → click on the program you want to start it.

In the folder of “/Public”, you will find a lot of useful reference manuals, such as OER, Offline wikis, e-books etc.

There are also a video tutorial and an Offline wikipedia (Xowa) icons available on the desktop.

Optional: Desktops (user interfaces)

Labdoo laptops come with Lubuntu (Linux operating system based on Ubuntu) and the LXDE and MATE desktops. LXDE and MATE are fast and easy to learn user interfaces. They can be installed on older laptops with minimum 512 MB RAM and will run fast.

Adjust languages, regional formats and keyboard settings

Depending on the country edoovillage is located, you may want to install one or more additional language(s) or keyboard(s).

You can adjust language setting by selecting Preferences → Language Support. You may get messages like “Language support not completely installed, install now”. Click on "Yes" and continue the installation.

In the next window select Install/Remove languages → select the language(s) needed → Apply → Apply System-wide.

The new languages will show up in the language list (as shown above). Lubuntu will use the first language setting in the table, then go to the next one, and continue. If no languages matched, it will use English as default.

To change priority of the languages → select and hold the right mouse button on the new language → move the language to its position and release the right mouse button → click Apply System-wide. The new language will be used after logout then login or after rebooting the computer.

Regional formats

You can also adjust the local currency, notation of numbers, date and time, if available. Click on the tab “Regional formats“ and select the format as shown in the list → Apply System-Wide.

Keyboard settings

You may skip this step if the laptop was cloned with images. Otherwise, you have to add a panel item to the task bar by clicking with right mouse button on the task bar → Add / Remove Panel Items → +Add → select "Keyboard Layout Handler" → +Add → optional: move the item position within the task bar by Up or Down.

Right click on the symbol "de" (keyboard layout handler) in the task bar (or another country abbreviation will be shown) → Keyboard Layout handler Settings → Remove the hook "Keep system layout", if activated, otherwise, you won’t be able to add new layouts) →

+Add → Add a new keyboard layout
-Remove → Remove a keyboard layout
↑Up → Move a keyboard layout entry in the list up
↓Down → Move a keyboard layout entry in the list up

The maximum number of keyboard layouts is 4..

Customize Look and Feel

You are able to change the Lubuntu graphical user interface (GUI), e.g. make it more look like Windows (if you want).

In order to activate a different Look and Feel click on the Lubuntu-start button in the left bottom corner of the screen → Preferences → Customize Look and Feel → select in the tab widget e.g. the theme Win10 light or another theme you like → click on the icon theme and select Windows 10 or other icons you like → close the window.

To undo / switch back to default Look and Feel just select another theme (Lubuntu-default) and icon theme (Lubuntu) - or other layouts that you like.

You have to get used to some settings of this "Windows" theme (remember, it is NOT Windows, it is Linux / Lubuntu, but it looks more similar to Windows).

Manuals, video tutorials and more

You can open the folder /home/labdoo/Public/ for more manuals, video tutorials, offline wikis etc. A tutorial video icon is placed on the desktop. You can watch it by using Firefox or other media player (view -> 1/2 size, zoom +/-).

Install codecs for multimedia, film and DVD

If you computer was installed on base of an image for cloning you will find on each desktop a script Legal Notice Patent and copyright laws operate differently depending on which country you are in. Please obtain legal advice if you are unsure whether a particular patent or restriction applies to a media format you wish to use in your country. Without executing this script you will not be able to watch videos or DVDs.
This script will install restricted codecs and restricted software for multimedia applications. Only proceed, if you are sure that you want to install these codecs and restricted software. Your computer must be connected to internet, while executing this script.

Programs for blind or visually impaired users

On the desktop you will find an icon magnifier, click on it and you will get a magnifier,which will follow your mouse. In the panel you will get now another magnifier icon. Right mouse click on that icon will open a settings menu.

Other programs for handicapped users are:

program description program name screen shot
Orca Screen reader; Wichtig: to toggle Orca on / off please press at the same time Alt + Super/Windows + o. To configure Orca open a terminal (User labdoo) -> type orca -s (Enter). Orca
pico2wave Tool reading marked (high lighted) text in any document. To toggle pico2wave on / off press the keys Alt + Super/Windows + p at the same time. Mark text before, then press these keys, text will be read. If marked text is too long an error will be reported. pico2wave
Elinks Text based web browser, running in a terminal (Link on desktop) Elinks

More information on solutions for handicapped users can be found here

set volume

In the panel you will find an icon to mute or set the volume louder or more quiet. Clicking on that icon will open a dialogue (mute or louder or more quiet). But there are much more settings for volumen, microphone etc., which can only be accessed by a programm called alsamixer:

Program Descriptions Program name Screenshot
alsamixer The program alsamixer is a tool to access all ALSA settings provides for the sound card. Frequently settings, which can not be directly accessed with the X-user interface, are deactivated or down-regulated. With Alsamixer you can quickly find and activate these settings. Open a terminal (press Ctl/Strg + Alt + t at the same time), type alsamixer (enter). Now you can adjust the volume settings, move the keys ← → to move to the next channel, ↑ ↓ to set it louder or more quiet. alsamixer

printer settings, CUPS
A printer can be added and administrated System Tools → Printers → + Add a printer. Most printers, connected to the computer or to network (LAN), will be recognized automatically.

For a more complex solution there is Cups (Common Unix Printing System), the most common print tool for Linux. Most printers can be used, jobs and spools administrated using CUPS. CUPS comes with an integrated web-server. This server can be used to set-up and manage a printer. Open a web-browser and open: http://localhost:631. Only user labdoo is allowed to access this page. In case a printer is locally connected to a computer you can allow access for other computer to this printer via LAN.

Help function F1, manual
By pressing the key F1 or help in the menu bar most programs will open a window and will show a manual for this program.

Reset and Restore user student
A student should log-in as guest or as user student, but never as user labdoo (only for teacher, administrator). But even being logged in as user student it might happen that menu bars or icons are deleted by mistake. Everything can be "repaired", but you have to know how - and this knowledge might be missing at schools. But we offer a good solution for that - on the labdoo users desktop you will find a script (Double click will start the script, run in a terminal). But be careful! This script will delete every(!) data / document stored or reset all setting done since you received the laptop! So make sure all data needed is assured! And sometimes this script is helpful, if you want to remove all data before giving the computer to another user.

Log in as administrator labdoo
labdoo: is administrator (admin, "Super User")! This means that the user labdoo has all access rights, e.g. for updating, installing additional software and educational content etc. But as admin you can accidentally "destroy" the laptop so that it does not start and can no longer be used, especially when users have none or poor experience with IT and Linux. And if the computer is "destroyed", the next Labdoo hubs / helpers for a re-installation or support are far away. That could become a real problem.
Therefore, sign up only as user labdoo, if you act carefully and already have experience with the administration of computers. Otherwise, it better uses the user student, who has not the administrator rights, but can also use all programs and content - and has less rights to destroy a computer by mistake.
The password to log in is at delivery labdoo (for all systems being delivered with Lubuntu 18.04 LTS or former releases, until about spring 2020). From Lubuntu 20.04 LTS ff. (starting about summer 2020) the password will change to labdooadmin. However, you should change this password immediately receiving the computer at your school / project, because the user labdoo has administrator rights and only the teachers / maintainers and experienced users should have access as admins!

Have fun learning and playing with your Labdoo laptop!
