Tipo quello, però non va, eccoti il policijyt.conf

codice:
<?xml version="1.0" encoding="UTF-8"?> 

<!DOCTYPE pkconfig PUBLIC "-//freedesktop//DTD PolicyKit Configuration 1.0//EN"
"http://hal.freedesktop.org/releases/PolicyKit/1.0/config.dtd">



<config version="0.1">
<match user="psykopear">
        <match action="org.freedesktop.hal.storage.*">
                <return result="yes"/>
        </match>
        <match action="hal-storage-mount-fixed-extra-options">
                <return result="yes" />
        </match>
        <match action="hal-storage-mount-removable-extra-options">
                <return result="yes" />
        </match>
        <match action="org.freedesktop.hal.power-management.*">
                <return result="yes"/>
        </match>
</match>
</config>
