"dontzap" where is it ?! :-/

[Vincent Trouilliez]

Hi list,

Just upgraded (in-situ) 8.10 to 9.04.

The release note suggest to use "dontzap--disable" command, for those
like me who miss the ability to restart X without restarting the whole
computer.

Problem: the "dontzap" command doesn't appear to be installed in the
system, command line says the command doesn't exist ! 

Is that a bug in the upgrade tool, have Ubuntu indeed forgotten to
install it ?

Where can I get it from ? 

They say you can add an option in xorg.conf to achieve the same, but
they don't give enough information to do that.


Regards,
