Anytime you see a \ at the end of a line, that means the line continues onto the next line. So if you copy and paste the command(s) you need to make sure you leave out the \ For example, the sudo rm -r command goes all together on one line.
Kubuntu has modified Konqueror to include features and settings that are commonly used, making the interface much simpler and easier to use. Some users, however, prefer to have all the bells and whistles. This guide shows how you can revert to the original Konqueror configuration and get back the original profiles on Dapper and Edgy.
Remove the Kubuntu default settings for Konqueror:
sudo rm -r /usr/share/kubuntu-default-settings/kde-profile \ /default/share/apps/konqueror
or launch Konqueror as root with
kdesu konqueror
If you wish to keep the Kubuntu default settings for future use or reference, move or rename the folder rather than deleting it.
Restore the original Konqueror configuration file:
sudo cp /usr/share/apps/konqueror/konqueror-orig.rc \ /usr/share/apps/konqueror/konqueror.rc
The configuration used by Konqueror is konqueror.rc, while the original is konqueror-orig.rc. If you wish to keep the Kubuntu default configuration for future use or reference, rename konqueror.rc before entering the command above. (The ~/.kde/share/apps/konqueror/konqueror.rc overrides this file)
Restore the other profiles.
This extra step is necessary in Dapper and Edgy, since these other profiles are not installed in these releases.
Go to konqueror Profiles and download the four profiles there. Put these profiles in either:
If you want the profiles to be visible to your user only
~/.kde/share/apps/konqueror/profiles
If you want the profiles to be visible to the whole system (all users and root)
/usr/share/apps/konqueror/profiles
Restart/Close Konqueror.
If the changes in the menu do not appear immediately, try logging out of KDE and loggin in again. Note that the konqueror.rc in ~/.kde/share/apps/konqueror/ overrides the one in /usr/share/apps/konqueror. You might need to delete the on in your home directory for the change to take effect.
