Running Knoppix 6.2.1 boot DVD:

While doing a long dd operation on my wife's laptop, I thought of closing the laptop to save power. When I opened it I was given an xscreensaver Login window with username knoppix (which cannot be changed). I tried blank password, "knoppix", "root"... nothing worked.

Eventually just had to shut power off to the laptop to regain access.

Is this a known issue? What is the password?

Thanks,

Michael
