- Open a console window
- Create a new .fdi file:
sudo gedit /etc/hal/fdi/policy/synaptics.fdi
- Put the following lines into the file:
<?xml version="1.0" encoding="UTF-8"?>
<deviceinfo version="0.2">
<device>
<match key="input.x11_driver" string="synaptics">
<merge key="input.x11_options.LockedDrags" type="string">True</merge>
</match>
</device>
</deviceinfo> - Restart Ubuntu (Restarting X-Server is not enough)
- Test it by dragging around items on your desktop. Enjoy.
