How to disable locking in LibreOffice?

Question

I want to disable file locking in LibreOffice, i.e., the creation of a hidden lock file in the directory of an opened document. The advice of the official documentation to comment out the second of the lines

SAL_ENABLE_FILE_LOCKING=1
export SAL_ENABLE_FILE_LOCKING

in /usr/bin/soffice (which is really a symbolic link targeting /usr/lib/libreoffice/program/soffice) does not help. The lock files are still created.

I use Ubuntu 12.04 which has LibreOffice 3.5.7.2.

Answer 1

To disable locking open Terminal application, then copy, paste and execute following command.

Notice: it's one long command, 12 lines, starts with "echo" and ends with "disable-file-locking.xcd".

echo '<?xml version="1.0" encoding="UTF-8"?>
<oor:data xmlns:oor="http://openoffice.org/2001/registry">
  <dependency file="main"/>
  <oor:component-data oor:package="org.openoffice.Office" oor:name="Common">
    <node oor:name="Misc">
      <prop oor:name="UseLocking">
        <value>false</value>
      </prop>
    </node>
  </oor:component-data>
</oor:data>' |
sudo tee /usr/lib/libreoffice/share/registry/disable-file-locking.xcd

To undo changes:

sudo rm /usr/lib/libreoffice/share/registry/disable-file-locking.xcd

Modify ~/.config/libreoffice/4/user/registrymodifications.xcu.

Add

<item oor:path="/org.openoffice.Office.Common/Misc"><prop oor:name="UseLocking" oor:op="fuse"><value>false</value></prop></item>

after the other <item oor:path="/org.openoffice.Office.Common/Misc">
