sudo vi /etc/event.d/control-alt-delete
Change the following line
exec /sbin/shutdown -r now "Control-Alt-Delete pressed"
to

Save and exit the file

Thanks!

to prevent the use of sysrq add this to your /etc/sysctl.conf:
kernel.sysrq = 0
if you don’t want to reboot you can just do a sysctl -p as root to get the changes effective

I think Ctrl + alt + backspace kills the x server.
