I just got my new Raspberry Pi 2 and installed RASPBIAN using NOOBs.
On start up I get this error. Its in a message box in the middle of the screen. If I hit ok the GUI seems to work find anyway.
GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed: Cannot determine user of subject
I have looked around and for similar errors people suggest this to fix the problem
Preferences->Desktop Session Settings" and un-check "PolicyKit Authentication Agent"
However there is no "Preferences->Desktop Session Settings" that I can find.
Does anyone else with a raspberry Pi 2 have this problem with a fresh install of RASPBIAN? Or do you know where I can find these Preferences.
