--- this is with gnome-3.10 and the session is started with gdm-3.10.0.1 (systemd-208-r3) Mounting USB-stuff works without root-pw ... the only feature needing this is when I start the virtual machine manager (for administration of the VMs on the various QEMU/KVM-hosts I run). But this is maybe by design and OK in a way. Stefan
