Lock keyboard but enable display to update.
I would like to lock the keyboard/screen but enable the display to keep updating (don't display a screen saver). I have looked at xscreensaver but it cannot lock the screen without running a screen saver. I have a graphical monitor program which I run on the console display but would like to lock the keyboard so nobody can "dork" with the system when I leave in the evening. I can do this on my CDE desktop in Unix and would like to do the same on my Linux Mandrake 7.2 installation.
