How to Uninstall Kubuntu Desktop

So you installed Ubuntu, sweet! And then you installed Kubuntu, just to try it out. Now you know what it’s like and you would like to switch back to Kubuntu.

So you installed Ubuntu, sweet! And then you installed Kubuntu, just to try it out. Now you know what it’s like and you would like to switch back to Kubuntu.

Like most people have found out, there were a few snags when going back to Ubuntuland. The first major snag is that the display manager is different. KDE display manager (KDM) is present instead of default GNOME display manager (GDM). The second issue is that users menus have been overloaded with apps; in addition to the default GNOME apps, there are now double the apps in the “Applications” menu. Both text editors from GNOME and KDE. Both contact managers. Both IM clients, Kopete and Pidgin, for GNOME and KDE, and so on.

Those are the two main reasons why some users want to go back to GNOME only. In this guide, I will show you how to fix those problems.

Canonical developers, makers of Ubuntu Linux, put more work into Ubuntu than Kubuntu. Contrary to what most people believe, Kubuntu and Ubuntu are not the same. Aside from the difference of desktop environments of GNOME vs KDE and the standard system programs like bash, ls, and the system programs in /usr/sbin, the underlying system that connects the desktops to the system are radically different. Mainly, the system scripts and the methods used. KDE has different configurations and tools to connect them, the same goes for GNOME, and ultimately, the user uses the “same” system differently! In addition, Ubuntu does a better job of hardware detection than Kubuntu, even though they are the “same” Linux distro!

Follow these steps in order to uninstall KDM, and to install GDM (the “default” option that came with Ubuntu). This procedure works as follows. As KDM is uninstalled, the KDM uninstall scripts uinstall KDM properly, reconfigure, and make sure that GDM (GNOME display manager) is installed and configured properly for next boot. GDM is thus set to default with all original settings – just as if Kubuntu desktop was never installed. Essentially, it’s a built in failsafe.

Here are the steps.

1 – Open Synaptic Package Manager [Ubuntu Main Menu :: System -> Administration -> Synaptic Package Manager]
2 – Remove KDM, and the relevant helper programs that Synaptic recommends to be removed.
3 – Make sure GDM is installed before rebooting! Most likely it is. If not, then install GDM by searching for it in Synaptic Package Manager. Verify that it is installed before going to next step.
3 – Reboot.
4 – You will be presented with normal GDM login

Now, to uninstall all of those pesky KDE apps like Amarok, Kate, Korganizer, Kontact, Kopete, KDE-wallet… that clutter your Ubnuntu menu do these following steps.

1 – Launch Synaptic [Ubuntu Main Menu :: System -> Administration -> Synaptic Package Manager].
2 – Locate via search, and uninstall kdebase-runtime-bin-kde4, kdebase-bin, and kdebase-workspace-bin.
3 – Congratulations you are now free of those KDE apps that you don’t use. Now they clutter you no longer.


I just re-installed PCLinuxOS on my secondary hard-drive, again. I used PCLOS about a year or more ago, switched to Ubuntu and didn’t like it because it failed to ‘find’ my USB ports (four of them) and it would thrash for about 1-2-minutes on EACH port before ‘moving on’ to the NEXT port which it could not find. -An 8-minute boot-time? Hell, if I wanted to WAIT I could just stay with Windoze and IE. :-\
I switched to Kubuntu and have been using that for about a year. Loved it. Many memory leaks aside, Kubuntu is probably the most ‘XP-like’ OS of the Linux type. But still, if did not like my soundcard, no sound. I could have probably found and installed a proper driver for it. I visited the Ubuntu forums and tried to get help. I don’t mean “give me the file” I mean I explained and asked for guidance and the rocket scientists there every one of them, responded with crap like “…what a wonderful opportunity for you to learn something new!” and NOBODY offered ANY kind of useful guidance. Not one person. It is experiences like this that turn people off of LINUX more than any aire of ‘geekiness’ associated with Linux.
But PCLinuxOS is notable for working ‘out of box’ and their mantra is “It just works” and yes, it does. Somewhat laid-out like XP and somewhat like VISTA, but it is pure Linux. While I am using KDE with PCLOS, there is a GNOME option (I am more familiar with GNOME, but KDE will do.)
