Installing Kubuntu 11.04 after installed Ubuntu 11.04

Hello folks.

You already have installed Ubuntu 11.04 but you haven’t liked the Unity. You want to try another window manager like KDE. So you can install Kubuntu, it comes with KDE.

To install Kubuntu, open a terminal and run:

sudo apt-get install kubuntu-desktop

During the installation, you will be asking about which display manager you want to leave as default. Choose kdm.

Now, if you want a full KDE installation that include multimedia, networking, graphics, education, games, system administration tools, and other artwork and utilities, still in the terminal, run:

sudo apt-get install kde-full

After that, restart your computer and in login screen, don`t forget to select KDE.

That’s it. See you next time.





Installing Kernel 2.6.39 in the Ubuntu 11.04 (Natty Narwhal)

Hello everybody.

The Kernel 2.6.39 was released in May 19th and includes support for ipset and interrupt handling can now be handled almost entirely by kernel threads, the ext4 file system and block layers are now able to scale better and show better performance and the kernel now includes a network backend for Xen virtualisation. A complete list about what has new in the Kernel you can get in www.h-online.com.

Now, it’s time to compile and install the new Kernel. Only to not repeat what was written in Installing Kernel 2.6.38.3 in the Ubuntu 10.10, follow this post to install this one and also don’t forget to change the reference to this one. In other words, instead of use linux-2.6.38.3.tar.bz2 you will must use linux-2.6.39.tar.bz2.

After run the command sudo make menuconfig, If you received the error below:

*** Unable to find the ncurses libraries or the
*** required header files.
*** ‘make menuconfig’ requires the ncurses libraries.
***
*** Install ncurses (ncurses-devel) and try again.
***
make[1]: *** [scripts/kconfig/dochecklxdialog] Error 1
make: *** [menuconfig] Error 2

Still In the shell, type:

sudo apt-get install libncurses5-dev

After that, run the command sudo make menuconfig again.

If you have any doubt about this post, feel free to ask me.

That’s it. See you next time.
