Error mounting a USB disk

Question

After last upgrade, I am getting this error when trying to mount an external hard disk.
If I try it using dolphin, it says
"An error occured while accessing 'disk name', the system responded: An unspecified error has occurred.: Not Authorized"
with
udisks --mount
I am getting the same error too.
If I use these with sudo (gksu/kdesu) it works just fine.
My user is part of storage group. Also made changes in
/usr/shre/polkit-1/actions/org.freedesktop.udisks.policy
to allow_inactive.
<allow_inactive>yes</allow_inactive>

Answer 1

I figured it out.
xinit is tasked with two jobs: finding a client to run, and finding a server to run it on.
The default behavior of xinit is to first look for commandline arguments that tell it what to do, e.g.:
xinit /usr/bin/awesome -- /usr/bin/X
This tells it to run awesome wm using the X server located at /usr/bin/X.
Failing commandline arguments, xinit then looks in your home directory for files .xinitrc and .xserverrc. If they exist, xinit will execute these files for the responsibility of the client and server, respectively.
If these do not exist, then xinit uses defaults built-in to the xinit program (launches xterm with /usr/bin/X). This is where startx differs. Under the same circumstance, startx will also search the /etc/X11/xinit directory for system wide xinitrc and xserverrc files. In all other ways startx is the same program, such that if you provide server arguments to startx then it will preference that over the default xserverrc, and thus you'll have the same problem.
All of this boils down to the appropriate X server arguments. The system wide xserverrc located in /etc/X11/xinit/xserverrc checks if the environment variable XDG_VTNR has been set (the current virtual terminal number, set by pam_systemd), and if it is then to use that same terminal number for the next X session by running:
exec /usr/bin/X vt$XDG_VTNR
So, there's three solutions:
Use startx instead of xinit
Make a symlink to the default xserverrc file in your home directory. This works because xinit still checks your home directory for xinitrc and xserverrc, just not the system wide files.
Make your own xserverrc that will do the correct thing, and put it in your home directory.
