hi all I met a problem . Does anybody help me ? I wrote a udeve rules for ntfs filesystem mount , and i want to using dbus-send to send a dbus signal .But it seems it can not work . When I debuge, i saw /var/log/message said it send ok. But , in fact , it can not work. Does anybody know this issue? PS: When exec udev rules, it should be root , and i am using a normal user to debug and see result.
