There is an explanation here: http://psychocats.net/ubuntu/graphicalsudo

kdesudo is for when activating a GUI (graphical interface) program with superuser privilege.

Example: kdesudo kate /etc/fstab to use kate to edit your fstab.

sudo is for when activating a non-GUI (or command line interface) program with superuser privilege.

Example: sudo apt-get update to update package lists.

kdesudo generally won't work if you use it to launch a non-GUI program. sudo generally will work to launch a GUI program but will very likely cause file ownership problems in your home folder if you do so.

Thank you guys, now it's clear like.
I switch to kubuntu few days ago and though it has something to do with KDE it self, but it is more like general rule.
Cheers
