Cannot test kubuntu as i dont have it installed. but if you are having problems try
sudo echo mem > /sys/power/state
that should suspend your laptop, i think :-)
you can try putting this in a shell script, also may have to add
<username> ALL=NOPASSWD: <path/scriptname>
to /etc/sudoers
not sure if all these will work with your laptop setup, xorg etc. but worth a try
