I’m using OpenSuse 11.4 (x86_64) with KDE 4.
It’s not possible to mount external USB (ntfs) disks with a non-root user using the Device Notifier or Dolphin. The error is:
Could not mount the following device: MyBook 2
org.freedesktop.UDisks.Error.PermissionDenied: Authentication is required
It is a permission problem; running Dolphin under root and clicking the USB disk mounts it without problems. The same should be possible to an ordinary user. The Update Applet does not work for the same reason (I can only install updates using yast).
Of course, I googled the error and there were a number of possible solutions, which I all tried. That includes allowing the action in the policy and adding the user in AdminIdentities local-authority. The file /usr/share/polkit-1/actions/org.freedesktop.udisks.policy contains “yes” for every option. Needless to say it doesn’t make sense and I’m out of options.
Hints and ideas are very much appreciated.
