how to install Kubuntu KDE in Ubuntu

Ubuntu default desktop uses Gnome window manager, which can be a difficult transition for Windows users. KDE desktop will be much more familiar to Windows users, such as KDE has something comparable to the start menu.

If you've installed Ubuntu, and you do not want to completely reset with Kubuntu, you can only install the KDE window manager to install kubuntu-desktop package and its dependencies.

You can install kubuntu using GUI tools, but the easiest way is to open a terminal window, and type the following command:

sudo apt-get install kubuntu-desktop

You will be prompted for a password, and then you will be asked again to ask if you really want to install. Press Y to continue, and let the install begin.

Download all the updates can take a while, so you might want to get a cup of coffee or something. You will be prompted to choose the login manager, which you can select as gdm (ubuntu) or kdm (kde). I decided to leave the default gdm.

Reboot the computer, and when you get to the login prompt, click the Options button in the lower left corner:

You will be prompted to select the session you want. Here we will click KDE to continue.

Login, and you should now see the KDE desktop! All applications are found in a menu-like "Start", as you can see:

Note: If you are running Ubuntu inside VMware and end up with some display issues which is really weird screen resolution is really great, but the desktop shows at 800 × 600 instead (see screenshot), there is a fix for this.

When I encountered this problem, I also can not use a mouse. I rebooted, and logged back into Ubuntu desktop instead of KDE, and go into the directory / etc/X11 /.

You may notice that your xorg.conf file backed up during installation xorg.conf.1 / KDE Kubuntu. Just copy xorg.conf.1 back into xorg.conf, reboot, and everything should be fine.

Again, do not mess with the xorg.conf file unless you are really experiencing this problem.
