We will make it the most simple possible.
Open a terminal and type in:
kdesu kwrite /etc/PolicyKit/PolicyKit.confyou will see a window to enter your root password, enter the root password. Then kwrite will have the root permissions to edit the file PolicyKit.conf
Then in the very first block of text, replace the
* at the end of the line:
<match action="org.freedesktop.hal.storage.*">
by the words
mount-removable, so that the block of text written like this:
<config version="0.1">
<match action="org.freedesktop.hal.storage.*">
<return result="yes"/>
</match>
becomes this:
<config version="0.1">
<match action="org.freedesktop.hal.storage.mount-removable">
<return result="yes"/>
</match>
That is how it is in the latest version of the package in 2010. (Theses ar polkit commands... )
