<p>i've just downloaded and booted the latest daily-live kde desktop iso. i see a screen with a password box and a button that says "KDE Plasma Workspace" which toggles itself to bold and back whenever pressed. and in the bottom right corner are "Suspend Hibernate Restart Shutdown". i've tried a few passwords. i've googled for instructions. i've perused the kubuntu site. i'm still clueless. what's the password needed here?</p>
