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.

use the good old xlock like this;
xlock -mode clock -geometry 100x100
this will use the clock screensaver in a 100x100 display
it locks your mouse and keyboard, but since it is in a
window u can still see your display output
see man xlock for all different screen savers and the
geometry can't be set to 0x0
try this in console and put it lateron somewhere in a script

some other 'nice', tho resource eating options;
-inroot or -inwindow these won't lock anything just showing
a screensaver background

some (hopefully) useful options and remarks
xlock options;
-dpmsstandby 0 -dpmssuspend 0 ; otherwise your screen
will die eventually (see also option dpms "off" in XF86Config-4)
- mousemotion grabs mouse movements for password check
+ usefirst useful, otherwise the first key entered must be
the first one of your password.

xlock works great with xfce, windowmaker, fluxbox etc, but results are different in KDE considering powermanagement; you should alter that in K's control center
and the -inroot thingy wont work on K cause K puts a own
layer on top of the rootwindow
good luck
