Check for error messages: open shell and type > sudo kdf, enter password, hit enter. and see if it complains about anything. Kdf should start from the menu entry (with a password prompt IIRC...I haven't used Ubuntu for a while). Install Kmenuedit. It allows manually adding, removing and editing the commands to start programs. It's possible that the start command for Kdf is entered incorrectly for some reason, like it needs to begin with sudo and it doesn't. Kdf requires that you manually edit /etc/fstab to show any mountable partitions, drives or volumes that weren't added automatically during install. Once you've correctly added the fstab entries, kdf conveniently allows mount and unmount of your volumes with a right click context menu. I think the Disk Utility you refer to is Red Hat Disk Utility. Be careful with that because it has a command to format drives. Kdf only mounts and unmounts drives.
