Getting Started

You can install a dual boot option and allocate disk space to each OS. As seen below..there is a side by side option

It is important to install Windows first..then Ubuntu

Ubuntu Boot Camp 2013Installing Ubuntu – Dual Boot Options

Installation Tips For Ubuntu

Setting Root password – In a default Ubuntu installation, the root account is disabled, Instead the user account created during the installation process is used with sudo (super user do) to access the administrator privileges.

Swap File With a default installation, Ubuntu creates a swap drive. It is generally 2 times the amount of RAM installed in the system...eg: 2 gb RAM = 4 gb swap file

Change the default OS at boot...if you have a dual boot system, you can choose which one is the default at boot time, to eliminate the need to choose each time

Selecting the correct country Be sure to select Tanzania, so that the updates are pulled from the local server so as reduce bandwidth usage. TZ is not in the list after installation is finished...not sure why?

Ubuntu Boot Camp 2013Root Access – What You Need to Consider

Most Unix and Linux systems have an account or group which enables a user to exact complete control over the system, often known as a root account. If access to this account is gained by an unwanted user, this results in a complete breach of the system. A root account however is necessary for administrative purposes, and for the above security reasons the root account is seldom used for day to day purposes (the sudo program is more commonly used), so usage of the root account can be more closely monitored.

Limit logins as root user. You should use sudo to execute root level commands as and when required. sudo does greatly enhances the security of the system without sharing root password with other users and admins.

Su “do” =Super User do

Sudo allows a system administrator to the ability to run some (or all) commands as root while logging all commands & providing a clear audit trail of who did what.

Sudo uses timestamp files to implement a "ticketing" system. When a user invokes sudo and enters their password, they are granted a ticket for 5 minutes. This avoids the problem of leaving root access open when others can physically get to your keyboard.

Unity Desktop – 8 Things To Help You Master It

1. The Launcher: at the left side of the screen is where you’ll launch frequently used applications and switch between running applications.

Click an application icon to launch or switch to it. Right-click an application icon to access its quick list.

For example, right-clicking the file manager icon will display a list of bookmarked folders you can open.

Ubuntu Boot Camp 2013The Unity Desktop



Launcher Con't To permanently attach another application to the launcher, right-click its launcher icon and select Lock to Launcher

Select the Unlock from Launcher option to remove any icon from the launcher.


2. The Dash Board: Open the Dash by clicking the Ubuntu icon at the top left corner of the screen. You can also press the Super key to open the launcher (the Super key is also known as the Windows key).

The home area in the Dash displays your recently used applications and files.You can search for applications by typing at the Dash.

Ubuntu includes many applications that aren’t attached to the launcher by default. To browse your installed applications, click the Applications lens at the bottom of the Dash and scroll through the applications.



3. Workspaces: Ubuntu includes multiple workspaces. Each workspace is its own desktop, allowing you to group application windows.

To view your workspaces, click the Workspace Switcher icon on the launcher.



3. Workspaces: You’ll see an overview of your workspaces and the windows open on each one. You can switch between workspaces from here. Drag and drop windows on the workspace switcher to rearrange your workspaces.



4. Indicator Menu: Many important functions are located in the indicator menus, located at the top right corner of your screen.

Whether you want to switch users, shut down your computer, control the volume level, or change network settings, you’ll find an option in one of the indicator menus.



5. Switching Between Applications: The Alt-Tab keyboard shortcut switches between applications in Unity, too. When you Alt-Tab, it only switches between windows on your current workspace.

The Alt-Tab switcher groups applications with multiple windows into a single icon. The three arrows to the left of the Firefox icon indicate that we have three Firefox windows open.



6. Hidden Global Menus: Unity uses a global menu – application menus aren’t located in the application’s windows, they’re located on the top panel.This may be somewhat confusing at first, because you can’t see the application’s menu until you mouse over the top panel.



7. The HUD: The HUD is a new, alternative way of accessing application menus. Instead of clicking the menu, press the Alt key and start typing a menu item’s name. You can search for and activate menu options without touching the mouse.

8.Keyboard Shortcuts Cheat SheetUnity has a lot of keyboard shortcuts, but you don’t need to remember them. Press and hold the Super (Windows) key and you’ll see a keyboard shortcuts cheat sheet.

When you press and hold the Super key, you’ll also see numbers over the application icons on the launcher. Use these numbers in combination with the Super key to switch to or launch applications.

For example, if the Firefox icon is in second place, we can press Super-2 to launch or switch to Firefox.


Unity Desktop – Ubuntu Tweaks

Ubuntu Tweak: Is an application to configure Ubuntu that provides many useful desktop & system options that the default Desktop environment does not provide. http://ubuntu-tweak.com/


File Management

The home folder is used to store the files and work of each individual user.This is the most important folder on the system, and can be compared to “My Documents” in Windows. Each user has a separate home folder.

Ubuntu Boot Camp 2013Navigating the File System & Your Home Folder

File Management

Desktop:The Desktop folder is inside the home folder and contains files that visually appear on the desktop as icons. If a file is dragged onto the desktop, it will appear in the Desktop folder. As well, removing a file from this folder will remove it from the desktop

Documents: Documents can be saved in this folder in order to keep the Home folder organized.

Downloads: When downloading files from email or a web browser, this is the default folder in which they will be saved.

Pictures: When downloading from your camera, this is the default location where the photos will be stored


File Management

Protected System Files: The core files required to operate are protected and have limited file permissions. Root owns them and therefore other users are unable to delete them or change them. However you can copy them
