On Ubuntu 10.10 you can’t have all the administrative or root power with the default user,created during the installation.If you want to login as root in GUI mode then use passwd command(Explained Below).If you think that why can’t I get all the root power with the default user,then the reason is obvious – the security policy of GNU/Linux or Ubuntu.It means that Ubuntu treats every user like a beginner if you are a advanced one then enable/hack and customize everything in the way you want.But this policy might be irritating some times specially while performing administrative task,but you can do that from Command Line by gaining temporary root power by using sudo commands.
On the other hand but if you don’t want to mess with commands,then other simple solution is to enable root login in gui mode,which can be done in few simple steps –
step #1 : Create Root user
To create ROOT user enter the following command at terminal(hit CTRL+ALT+T to open Terminal).Then enter a new password twice for root user.
ubuntuuser@ubuntuuser-desktop:~$ sudo passwd root
[sudo] password for ubuntuuser:
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully…..
step #2 : Login as Root in GUI mode
To use root power in gui mode ,logout from the current session and in login window select other user;enter root as username and in place of password enter the one as defined in step1.That’s all ..enjoy the real power of Ubuntu 10.10.
Caution : Always Remember that in gui mode ROOT power is very dangerous if you aren’t sure what you are doing..so use the root power carefully because one mistake can damage/corrupt you whole system & …..that’s why it’s recommended to come back in normal mode(non root) after completing the critical tasks.You can also use some tools like ubuntu tweak or ubuntu control center to gain root power.
Java is an Object Oriented programming language whose syntax and features has highly influenced by C/C++.Java programs can also be embedded in web pages which requires Java Run Time Environment(JRE) in order to get executed.That’s why after the fresh installation of Ubuntu 10.10 Maverick Meerkat you would require JRE for surfing Internet without any lack of functionality;because a lot of websites now uses java Applets to do some client side computation.On Ubuntu open JDK(java Development Kit) is recommended.
Installing Java Run Time Environment in Ubuntu 10.10
To install JRE just go to Synaptic Package Manager and search for ‘jre’ and select the packages that says open jre/jdk.After marking the package click on Apply button to begin the installation procedure.Then wait until the installation is complete….that’s all you have installed JRE successfully on your Ubuntu 10.10 Maverick Meerkat.
Eclipse IDE(Integrated Development Environment) is probably the open source and free IDE’s.For Java it’s best.. due to a lot of functionality,good navigation and GUI Design.Eclipse platform is perfectly modular so After installing Eclipse-Platform(developed by IBM) you can install any other components/toolkits to increase it’s functionality.e.g by adding JDT(Java Development Tools) packages you can enjoy java programming with Eclipse,similarly CDT(C/C++ Development Tools) for C/C++ fun.There are lot of Eclipse versions are available for different programming language e.g for web development(As you see in the above screenshot) java script version of Eclipse is also available,For PHP developers ,a dedicated PHP version is available and. ..so on.Some Developers says Eclipse is very complex and not recommended for beginners ,sure there is little trade off between the functionality and complexity but overall it’s not so tough and free tutorials/whitepapers are available on internet,to increase the fun of programming in Eclipse.
Installing Eclipse in Ubuntu 10.10 Maverick Meerkat
In Ubuntu 10.10 Maverick Meerkat the Ubuntu Software Center is a good place to install and manage applications without any hassle,specially for beginners who don’t have any previous experience with GNU/Linux based operating system e.g Ubuntu 10.10.On the other hand if you want some more details about the package then Synaptic Package Manager is recommended.
From Ubuntu Software Center(or Synaptic package manager)
Go to Ubuntu Software Center and search for ‘eclipse’ and click on install(see the snapshot) to begin the installation procedure.Wait for the installation to complete and then go to Applications->Programming->Eclipse to load the Eclipse IDE Platform.
Alternative Method to install Eclipse on Ubuntu 10.10
Another simple method to install any version of Eclipse IDE is to download the Required packages from the Eclipse’s official website(Link is given below) and extract it to the required directory.
#1. Download the Eclipse IDE
#2. Extract the archive to any directory.Then create a shortcut on the desktop or in the menu to access it,other ways to open eclipse is “click on the file the you want to open with eclipse and select open with and locate the executable,don’t forget to check the box which says remember this application for selected file type”.
If you are a beginner Ubuntu User then you should know that Ubuntu 10.10 Maverick Meerkat or any other version of Ubuntu uses GNOME as Default Desktop,but if you want to install KDE on Ubuntu 10.10,then it’s very simple because all the Linux based systems are perfectly modular.In general I like GNOME much as compare to other Desktops like KDE,LXDE,XFCE…. but it’s totally personal experience if you want KDE desktop in Ubuntu then just follow the simple steps given below.Many Ubuntu users agree on this point that KDE has better look as compare to other desktop.If you are a KDE Fan then there is one more point – A dedicated version of KDE+Ubuntu 10.10 = Kubuntu 10.10 is also available.
Installing KDE Desktop on Ubuntu 10.10
KDE can be installed in many ways but the best method is to install it from Synaptic package Manager.Before installing KDE you should select the package i.e Standard,Minimal or Full,because KDE desktop also contains KDE based applications.So choose the package you need.Then mark the left box in synaptic package manager and click on Apply to Begin installation.Depending on your internet bandwidth it wouldn’t take more than 15 minutes to finish the installation procedures.If you are still not sure about the above steps then go here step wise instruction for KDE installation.
Login in to KDE Desktop Session
Logout from the current login session.At the login prompt choose your username,enter password and select Desktop as KDE at the bottom Right Menu.Then login as usual..Then you will be able to enjoy Ubuntu 10.10 with KDE.
