[SOLVED]Mounting usb drives "not authorized" with thunar-volman (XFCE)

Hi,

I'm new to Arch (even though I must be approximately at my 15th try at installing it properly) and I have a problem with thunar-volman.

Whenever I log in as user, and try to mount a usb drive with thunar, let's say I want to plug a drive labeled Ext3_8Go, I get the same message in a pop-up window : "Failed to mount Ext3_8Go (or anything close, not in English in the text), not authorized (that part is in English)"

My install is :
- net install
- partitions : 9Go for /, no swap, no separate /home
- packages : base and base-devel. The only modifications in the package list is that I remove ppp, pcmciautils, and xfsprogs.
- config : at the install stage I only modify rc.conf to change LOCALE and HOSTNAME, and pacman's mirrorlist to allow all French mirrors in addition to the one at the top.


When the usb installation is over, I run this script :
"installation_xfce.sh"  (there may be some errors left, I modify this script as I learn) :

#!/bin/bash
# expected environment : freshly installed archlinux, login : root.

echo "Are you connected to internet ? If not, please Ctrl+C and reload this script when connected"
echo "Otherwise, press ENTER to continue installation"
read var_dummy

echo "Creation of the user : please type in your user name :"
read var_username
useradd -u 1000 -g users -G audio,lp,storage,optical,video,wheel,games,power,network -d /home/$var_username/ -s /bin/bash -m $var_username
echo "You will now be asked to create the password for this user:"

reboot

I can mount as a user, no password asked, with :

udisks --mount /dev/sdb2

but the GUI method tells me "not authorized".

"groups user" outputs :

lp wheel games network video audio optical storage power users

the command "ck-list-sessions" outputs :

Session2:
	unix-user = '1000'
	realname = ''
	seat = 'Seat1'
	session-type = ''
	active = TRUE
	x11-display = ':0.0'
	x11-display-device = '/dev/tty7'
	display-device = ''
	remote-host-name = ''
	is-local = TRUE
	on-since = '2011-08-15T08:56:03.716103Z'
	login-session-id = '1'
Session1:
	unix-user = '1000'
	realname = ''

	is-local = TRUE
	on-since = '2011-08-15T08:56:03.573029Z'
	login-session-id = '1'

For those who don't have time to read the installation script, DBUS is in the DAEMONS list of rc.conf, and .xinitrc launches : exec ck-launch-session startxfce4

Any idea ?

Re: [SOLVED]Mounting usb drives "not authorized" with thunar-volman (XFCE)

Can you post your .xinitrc? I had problems with dbus getting launched from all over the place, resulting in the same errors as yourself. I had to comment out some things in the "default" .xinitrc that I copied from /etc/skel/.xinitrc, because one of the script started a dbus-session I did not want.

Re: [SOLVED]Mounting usb drives "not authorized" with thunar-volman (XFCE)

Here's my ~/.xinitrc :

#!/bin/sh
#
# ~/.xinitrc
#
# Executed by startx (run your window manager from here)

if [ -d /etc/X11/xinit/xinitrc.d ]; then
  for f in /etc/X11/xinit/xinitrc.d/*; do
    [ -x "$f" ] && . "$f"
  done
  unset f
fi

exec ck-launch-session startxfce4
thunar --daemon &

and here's the output of "ps aux|grep dbus" :

dbus       727  0.0  0.0  13252  1396 ?        Ss   13:25   0:00 /usr/bin/dbus-daemon --system
user      1483  0.0  0.0  19840   548 ?        S    13:25   0:00 /usr/bin/dbus-launch --sh-syntax --exit-with-session
user      1484  0.0  0.0  14016  1664 ?        Ss   13:25   0:00 /usr/bin/dbus-daemon --fork --print-pid 5 --print-address 7 --session
user      1736  0.0  0.0  10568  1000 pts/0    S+   13:30   0:00 grep dbus

I don't know if it helps

Re: [SOLVED]Mounting usb drives "not authorized" with thunar-volman (XFCE)

This is the problem. dbus-launch needs to be run AFTER ck-launch-session, which does not happen in this case. The if-for loop before the line with "exec..." runs a script in /etc/X11/xinit/xinitrc.d/ that runs dbus-launch, and so startxfce4 does not. Just comment out the whole if-fi thing and you are good to go smile There's more info here.

Re: [SOLVED]Mounting usb drives "not authorized" with thunar-volman (XFCE)

Thanks a lot !
That worked !
I stumbled across this part of the wiki several times before, but didn't really understand so I had not tried.

If anyone's interested in the script, here's the corrected version :

#!/bin/bash
# expected environment : freshly installed archlinux, login : root.

echo "Are you connected to internet ? If not, please Ctrl+C and reload this script when connected"
echo "Otherwise, press ENTER to continue installation"
read var_dummy

echo "Creation of the user : please type in your user name :"
read var_username
useradd -u 1000 -g users -G audio,lp,storage,optical,video,wheel,games,power,network -d /home/$var_username/ -s /bin/bash -m $var_username
echo "You will now be asked to create the password for this user:"
