Having just updated to KDM4, as well as updating the version of KDE4, I
have gone into drakconf -> Boot -> Set up Display Manager to check the
settings and the display is empty. If I click on ok the message 'The
package needs to be installed. Do you want to install it?'. Clicking ok
then produces a dialog box that says "No package named". Clicking ok
then produces a warning dialogue that says "The following packages
contain:", and lists a large number of packages. How do I identify what
has caused this and what the fix is?

regards,
Steve
