try to edit /etc/xdg/autostart/lxpolkit.desktop and change the entry from NotShowIn=GNOME;KDE; to NotShowIn=GNOME;KDE;LXDE;EverywhereSean wrote:Recently received my Raspberry Pi 2, I installed NOOBS 1.4.2 and did the custom "raspi-config" stuff. When I type "startx", it gives me "GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed: An authentication agent already exists for the given subject", I've lurked online for a solution. Everyone suggests the "lxsession-edit" -> uncheck "LXPolKit", but mine doesn't display "LXPolKit" for me... What do?
Code: Select all
sudo apt-get update && sudo apt-get -y dist-upgrade && sudo apt-get -y --purge autoremove && sudo apt-get -y autoclean
Ah, dang. I forgot to mention that my Pi2 is running the latest Raspbian and I am still getting the same error message.beta-tester wrote:try to edit /etc/xdg/autostart/lxpolkit.desktop and change the entry from NotShowIn=GNOME;KDE; to NotShowIn=GNOME;KDE;LXDE;EverywhereSean wrote:Recently received my Raspberry Pi 2, I installed NOOBS 1.4.2 and did the custom "raspi-config" stuff.

that worked to me in the past...
with the newer Raspbian i didn't have that issu anymore...
possibly you should do an dist-upgrade from your old Raspbian to the newest.why you are using NOOBS 1.4.2... use always the newest of the newest... (currently NOOBS 1.7.0)Code: Select all
sudo apt-get update && sudo apt-get -y dist-upgrade && sudo apt-get -y --purge autoremove && sudo apt-get -y autoclean
oops... it is that an old post...
