Hi,   
  
the acpi screenblanking screens rely on xscreensaver running. Kde does not use xscreensaver by default so  
xscreensaver-command does not work (And as a side effect, when you open the lid of the laptop x.org is using all cpu..  
when the xscreensaver-command calls are removed this doesnt happen)..  
  
the script needs to check to see if xscreensaver is running. if not then it should perhaps try to lock the screen the  
kde way.  
  
here are the changes which make /etc/acpi/lid.sh work on a kde system (this is with the removal of 
xscreensaver-command stuff. you will have to sort out how to detect what system is running etc) 
 
first /etc/acpi/lid.sh 
 
#!/bin/sh  
  
. /usr/share/acpi-support/power-funcs  
  
[ -x /etc/acpi/local/lid.sh.pre ] && /etc/acpi/local/lid.sh.pre  
  
getXuser;  
  
grep -q closed /proc/acpi/button/lid/*/state  
if [ $? = 0 ]  
then  
        . /usr/share/acpi-support/screenblank  
fi  
  
[ -x /etc/acpi/local/lid.sh.post ] && /etc/acpi/local/lid.sh.post 
 
and here is /usr/share/acpi-support/screenblank 
 
#!/bin/sh 
 
su $user -c "(kdesktop_lock --forcelock --blank)" 
xset dpms force off
