Previously I had in KDE3 a submenu "Yast modules". It included besides other, a package manager.

I do not know what exactly I did but this sub-menu suddenly disappeared. Yast2 does not start from console in graphical mode. So now I have to load Gnome to add/remove software or use Yast from console.

Can anybody please advise me what package(s) should I (re)install to restore the "yast modules" menu?
