Completely remove KDE desktop

[atentik]

Is there a way to completely remove KDE desktop? After install kde-desktop on my laptop, I notice a strange start up screen ... Blank screen. I am not completely sure if the blank screen is attributed to the installation of kde-desktop since it started a few times normally after the installation. Somehow, my guts tells me to completely remove the kde-desktop and things will be somehow solve. I tried
sudo aptitude remove kde-desktop to remove the kde-desktop but it won't remove. Is there any other thing I can do to completely remove this desktop and/switch to gnome startup. I also tried
switchdesktop gnome but to no avail. If there is a way to completely remove KDE-desktop, please let me know.

Thank you.

remove all of KDE and its apps?

P.S. i got this code from the PureGnome link.

Correct me if I'm wrong, but kde-desktop is a metapackage. It depends upon all of the applications in the full KDE install, but they are not dependent upon it. The effect is that you can pull all of the usual packages to get KDE by pulling it from apt. The converse means that removing the kde-desktop package does not really remove anything at all.

Atentik, purging kde from your Ubuntu or other *buntus ain't as easy a task as a mere sudo apt-get --purge remove kde-desktop.

Firstly before we begin, I assume you have already an alternative to fall back on e.g. GNOME, Xfce, LXDE or a WM such as fluxbox, openbox, etc. Ok assuming you have one or more, the steps are as follow:

1.
Make a listing of all kde and qt-related packages installed
dpkg --get-selections | grep kde
dpkg --get-selections | grep qt

2.
Remove all the kde and qt packages identified using dpkg --get-selections in 1., proceed to purge remove them all with sudo aptitude --purge remove. You may need to keep some of the kde/qt apps and libs if you use things like amarok, smplayer, kmplayer, minitube, xbmc, etc. E.g. for those with smplayer installed, do a aptitude why libqtcore4 and you'll see soon enough the dependency relationship between smplayer and libqtcore4. So you need to know what is it that you actually want (i.e. a KDE-free system or a pure GNOME/GTK install without a single kde/qt app)? Aptitude is your best friend. For more on what aptitude is capable of issue aptitude -h at the commandline for more.

Beware that certain indiscreet, stealthy but still kde/qt packages such as soprano-daemon and soprano-daemon-sesame may still remain. Purge them too (with sudo aptitude --purge remove soprano-daemon soprano-daemon-sesame) for a truly KDE/QT-free desktop.

3. Purging residual configs, verifying that KDE/QT have been totally purge and housekeeping
Type these commands to remove residual configs as well as performing badly needed housekeeping:

sudo deborphan | xargs sudo apt-get -y remove --purge && sudo deborphan --guess-data | xargs sudo apt-get -y remove --purge; sudo apt-get autoremove && sudo aptitude purge '~c'; sudo apt-get autoclean

and then re-issue these commands to make triply sure.
dpkg --get-selections | grep kde
dpkg --get-selections | grep qt

That's all. All the best guys!

Forgot to mention the problem was SOLVED by wojox method. Thanks.
