Automatically Kill Lightdm and Login tty4

[Dr.Paneas]

I want to write script that does the following:

kill the X server and stop lightdm


kill_X()
{
# Stop the xserver (lightdm)
sudo chvt 4 && sudo service lightdm stop
}


Then I want to login automatically to tty4 and automatically run the script itself.


auto_run_script()
{
if [ -s ~/.bash_profile ]; then
cp ~/.bash_profile ~/.bash_profile.backup
test=`grep "sh $PWD/$0" ~/.bash_profile`
if [ -z "$test" ]; then
echo "sh $PWD/$0" >> ~/.bash_profile
fi
else
echo "sh $PWD/$0" >> ~/.bash_profile
fi
}


and for the autologin part I use the Upstart


goto=/etc/init

# backup
sudo cp $goto/tty1.conf $goto/tty1.conf.backup
b=--autologin

sudo sed -i 's_/sbin/getty_/sbin/mingetty_g' /etc/init/tty1.conf

b3=`awk '/exec/ { print $3 } ' /etc/init/tty1.conf`
sudo sed -i "s/$b3/$b/g" /etc/init/tty1.conf

b4=`awk '/exec/ { print $4 } ' /etc/init/tty1.conf`
sudo sed -i "s/$b4/$us3r/g" /etc/init/tty1.conf


The problem is that when I kill X server, the automated login doesn't work. I have to reboot the computer in order to "confirm" the change in Upstart. Is there any way to do it without restarting ?
