Re: [SOLVED]DBus sockets file no exists in /tmp

Stop using dbus-launch.

these dbus-launch is automatically created by system.

and if my program is not started by dbus-launch, some of function is abnormal.

Is there any wiki pages or artical which discribe how can I solve my problem ?

Re: [SOLVED]DBus sockets file no exists in /tmp

No, they are not automatically created "by system". I have no idea how you've set up your WM to launch with dbus-launch, but undo it.

Re: [SOLVED]DBus sockets file no exists in /tmp

These dbus-launch seems like created by lightdm:
/etc/lightm/Xsession

>> cat Xsession 
#!/bin/sh
#
# LightDM wrapper to run around X sessions.

echo "Running X session wrapper"

# Load profile
for file in "/etc/profile" "$HOME/.profile" "/etc/xprofile" "$HOME/.xprofile"; do
    if [ -f "$file" ]; then
        echo "Loading profile from $file";
        . "$file"
    fi
done

# Load resources
for file in "/etc/X11/Xresources" "$HOME/.Xresources"; do
    if [ -f "$file" ]; then
        echo "Loading resource: $file"
        xrdb -merge "$file"
    fi
done

# Load keymaps
for file in "/etc/X11/Xkbmap" "$HOME/.Xkbmap"; do
    if [ -f "$file" ]; then
        echo "Loading keymap: $file"
        setxkbmap `cat "$file"`
        XKB_IN_USE=yes
    fi
done

# Load xmodmap if not using XKB
if [ -z "$XKB_IN_USE" ]; then
    for file in "/etc/X11/Xmodmap" "$HOME/.Xmodmap"; do
        if [ -f "$file" ]; then
           echo "Loading modmap: $file"
           xmodmap "$file"
        fi
    done
fi

unset XKB_IN_USE

# Run all system xinitrc shell scripts
xinitdir="/etc/X11/xinit/xinitrc.d"
if [ -d "$xinitdir" ]; then
    for script in $xinitdir/*; do
        echo "Loading xinit script $script"
        if [ -x "$script" -a ! -d "$script" ]; then
            . "$script"
        fi
    done
fi

# Run user xsession shell script
script="$HOME/.xsession"
if [ -x "$script" -a ! -d "$script" ]; then
    echo "Loading xsession script $script"
    . "$script"
fi

echo "X session wrapper complete, running session $@"

dbus-launch --exit-with-session $@

If I comment out last line, I can not enter my awesome WM.....

Re: [SOLVED]DBus sockets file no exists in /tmp

That is not the same file that's included with the current package. What version of lightdm are you running?

Re: [SOLVED]DBus sockets file no exists in /tmp

well I checked file list of lightdm :
https://www.archlinux.org/packages/extr … 4/lightdm/

there is /etc/lightdm/Xsession with it.

Re: [SOLVED]DBus sockets file no exists in /tmp

And yet, the file in the package is here: https://git.archlinux.org/svntogit/pack … es/lightdm

Re: [SOLVED]DBus sockets file no exists in /tmp

changing' dbus-launch $@' to 'exec $@' reduced the number of dbus-daemon process.
but...still...some program is work abnormally without dbus-launch command.
such as :

hacksign@XSign [14:00:21] : /tmp 
>> indicator-keylock 

(indicator-keylock:1902): Unique-GDBus-WARNING **: Unable to open a connection to the session bus: 无法连接：拒绝连接

(indicator-keylock:1902): GLib-GIO-CRITICAL **: g_dbus_connection_call_sync_internal: assertion 'G_IS_DBUS_CONNECTION (connection)' failed
fish: 'indicator-keylock' terminated by signal SIGSEGV (Address boundary error)

but with dbus-launch indicator-keylock, it's ok.

So is there any method to create /tmp/dbus-xxxx file when window manager launched ?

Re: [SOLVED]DBus sockets file no exists in /tmp

Stop obsessing about /tmp. It's wrong. DBUS_SESSION_BUS_ADDRESS should be pointing to a file in /run. If it's not, either you didn't merge a pacnew file for pam, or something else is screwing up the variable.

Re: [SOLVED]DBus sockets file no exists in /tmp

I'm not sure how you managed to have a file that differs from the original package on a properly updated system.
Unless you manually edited it or have some pacnew file laying around that you still need to merge, this should not happen.

Make sure your system is up-to-date, then check your system for any pacnew files that you still need to merge manually; https://wiki.archlinux.org/index.php/Pa … c.2A_files
After that you can try to run `pacman -Qk` to check for missing files (optionally you can specify the 'k' twice to check more details of the file, such a modification time)

Also, can you give us the the output of the following command?

printenv DBUS_SESSION_BUS_ADDRESS

EDIT: or if that doesn't work

echo ${DBUS_SESSION_BUS_ADDRESS}

Re: [SOLVED]DBus sockets file no exists in /tmp

I found if I start X first then start awesome, DBUS_SESSION_BUS_ADDRESS is properly set to /run/user/xxx/dbus
But if I start lightm as login manager then launch awesome with lightdm-gtk-greeter DBUS_SESSION_BUS_ADDRESS is set to /tmp/dbus-xxxxx where xxxxx is an random string.
