I recently upgraded a minimal installation of Ubuntu (with no full-fledged DE) from precise to saucy and since doing so I'm no longer able to mount removable drives as a normal user. I googled a bit and found it's something related to policykit... but I can't find any example of how to invoke policykit in an .xinitrc file, i.e., without using a display manager. Also, the Ubuntu repos have the following packages:
lxpolkit policykit-1 policykit-1-gnome policykit-desktop-privileges
and they each have similar descriptions, so I'm not even sure which of them I should install.
Does anyone using startx/xinit to start X have a working config with policykit and/or instructions they can share?
