[SOLVED] DBUS boot problems - Mounting system devices as a normal user

I have the [testing] and [community-testing] repositories enabled. A few days ago, probably due to an update, I started having trouble mounting devices and the shutdown/reboot options don't show up anymore on the LXDE exit menu.

I use gvfs for mounting devices as a normal user with PCManFM or Thunar. The error message is "Authentication is required".

After some testing, I found out that by restarting dbus, I could start mounting devices again:

/etc/rc.d/dbus restart

So my guess is that there's some problem with dbus startup. I have it in DAEMONS of rc.conf, as well as .xinitrc, the daemon seems to start correctly on boot, and it worked previously, so I have no idea of what could be wrong.

My ~/.xinitrc:

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

if test -z "$DBUS_SESSION_BUS_ADDRESS" ; then
    eval 'dbus-launch --sh-syntax --exit-with-session'
fi

numlockx && exec ck-launch-session dbus-launch startlxde

My /etc/rc.conf:

#
# LOCALE: available languages can be listed with the 'locale -a' command
# DAEMON_LOCALE: If set to 'yes', use $LOCALE as the locale during daemon
# startup and during the boot process. If set to 'no', the C locale is used.
# HARDWARECLOCK: set to "", "UTC" or "localtime", any other value will result
#   in the hardware clock being left untouched (useful for virtualization)
#   Note: Using "localtime" is discouraged, using "" makes hwclock fall back
#   to the value in /var/lib/hwclock/adjfile

#   Note: if unset, the value in /etc/localtime is used unchanged

#   - broadcast: broadcast address (ignored for DHCP) (optional)
#   - gateway: default route (ignored for DHCP)

# If you are sure nothing else touches your hardware clock (such as ntpd or
# a dual-boot), you might want to enable 'hwclock'. Note that this will only
# make a difference if the hwclock program has been calibrated correctly.
#
# If you use a network filesystem you should enable 'netfs'.

Re: [SOLVED] DBUS boot problems - Mounting system devices as a normal user

I solved it.

The Wiki page for Mounting for normal users with PCManFM tells to create a "/etc/polkit-1/localauthority/50-local.d/55-myconf.pkla" file specifying the privileges to grant to the user. The problem is that it does not include the privilege needed to mount internal drives (which was what I was trying to mount). To fix it, I added:

;org.freedesktop.udisks.filesystem-mount-system-internal

To the "Action=..." line.

(Though I have no idea why it worked before it broke, or why restarting dbus after initializing my WM fixed it.)

As for the power issues, I've concluded that it was working, but restarting dbus after initializing my WM broke it (my bad for not checking it before restaring dbus). So it all works now.
