What is the default root password?

There is no root password set as default. If KDE needs administrator privileges you should use your user password instead. You can also edit files as root from Konqueror with right click -> Actions -> Edit as Root. See the Root Sudo wiki page.

Are user setting preserved upgrading from Hardy to Intrepid?

If you were using the standard Kubuntu desktop with KDE3, those settings will be migrated when you upgrade. Settings for the Kubuntu KDE4 Remix are not automatically migrated, but are preserved in your home directory so they can be manually moved from .kde4 to .kde.

How do I change Konqueror back to the default KDE profiles?

Kubuntu comes with a simplified Konqueror profile to make things more use friendly compared to default KDE. To get back to the default KDE profiles: sudo rm -r /usr/share/kubuntu-default-settings/kde-profile/default/share/apps/konqueror [this one not needed in gutsy] sudo cp /usr/share/apps/konqueror/konqueror-orig.rc /usr/share/apps/konqueror/konqueror.rc To enable Konqueror to open tar and zip files: sudo rm -r /usr/share/kubuntu-default-settings/kde-profile/default/share/mimelnk/application/
