1. Screensaver to lock your Linux console(s) Lockvc is a console-locking-program combined with some nifty vga- screensavers. All virtual consoles get locked, i.e. you cannot change to another VC and you can't stop the program by pressing any key-combos. You can only exit the program by entering your system-password. Root's password will also terminate lockvc. To make the program available to any users, lockvc is installed setuid by default. Use dpkg-statoverride if you want to change this. From Debian 3.0r0 APT
