I boot from Hardened Live CD, install and compile my new Gentoo system. It works fine alone. but after a period of time, when I want to unlock the system from x-screen-saver, I can't input anything from keyboard even numlock is not responding. the mouse is working fine, and I tried to change to another keyboard including USB and PS2 (I originally usually PS2), but still failed to input. It happened twice, and the keyboard is totally not responding, so I can get any error message.
Two+ year old Hardened LiveCD will not be updated. Closing as WONTFIX.
