[rhelv6-list] howto enable CTRL+ALT+BACKSPACE on RHEL6.1

[Tiziana Manfroni]

Hi all, I would like to know howto enable CTRL+ALT+BACKSPACE for all 
user.
I try to create /etc/X11/xorg.conf

Section "ServerFlags"
         Option          "DontZap"               "false"
EndSection

but it doesn't work.
Then I try to insert into /usr/share/hal/fdi/policy/10osvendor/10-x11-input.fdi
<match key="info.capabilities" contains="input.keys">
       <merge key="input.x11_driver" type="string">keyboard</merge>
#new line
       <merge key="input.xkb.options" type="string">terminate:ctrl_alt_bksp</merge>
#
       <match key="/org/freedesktop/Hal/devices/computer:system.kernel.name" string="Linux">
         <merge key="input.x11_driver" type="string">evdev</merge>
       </match>
</match>

I don't understand where is the error. Can you help me?

Thanks in advance
