ubuntu vs. kubuntu

The difference is the window controller Ubuntu uses GNOME and Kubuntu uses KDE so if you don't like GNOME then you can still use Ubuntu with KDE and they call it Kubuntu that is the primary difference from what I understand of it is that the only difference is the Desktop enviorment. thats it other wise it is the same exact program.

I don't know, the first one I think is correct. But as of what I know Kubuntu is the server OS of Ubuntu, similar to those Windows server stuff...Hmm...I think I should do more research about Linux.

Ubuntu and Kubuntu are both sponsored by Canonical Ltd. for Linux. Both are using same basic kernels. As mentioned above, Ubuntu and Kubuntu are different windows or desktop managers. Ubuntu desktop are from Gnome based system, softwares or applications...... Kubuntu desktop are from KDE based system, softwares or applications. These Gnome and KDE are merely competitors to each others or rivals in desktops system in any Distro of Linux whether using Suse, Fedora . . . etc. .. and I think soon KDE will make on the Microsoft Windows Systems, and there are already beta versions that you can download and install it within the Windows environment. Gnome and KDE are just more a popular in desktop system manager. There are others desktop managers such as XFCE, Enlightenment, Fluxbox and so on. Actually you can install the Gnome and KDE or the Ubuntu and Kubuntu at the same time....and also with other desktop managers. Ubuntu or Gnome desktop the functionalities are simple to use, basic, clean and yet is powerful. It is like using a Mac OS Kubuntu or the KDE desktop has lots of applications and more diversified than Gnome..And it is like the MS Windows. For beginners it is easy try on Ubuntu or the Gnome systems...then later you can install the Kubuntu or KDE and other Desktop managers without reformatting or making partitions.... tnx a lot ^_^
