I am new to the Raspberry Pi. When I tried to install my picamera, everything went well until I put in the command startx. I got the following error:

GDBus. Error.org.freedesktop.PolicyKit.Error.Failed: An authentication agent already exists for the given subject 

Confused if this is...

  • I blame systemd or one of its "helpers" - but then I would and it may not be anything at all to do with it... 8-/ – SlySven Jan 12 '16 at 2:27

Encountered problem before. Here's what to do:

  1. Open terminal

  2. run lxsession-edit (forgot whether to run as root or not)

  3. Uncheck "LXPolKit"

  4. OK, then reboot.
