Can't launch i3wm with startx [closed]

Hi,

Since few days, a very strange problem occurs : i3 can't be launched without GDM 3 days ago, SLiM stop launching i3. I have try to launch i3 with a simple startx with my .xinitrc :

#!/bin/sh
exec i3 -V > ~/.i3/i3.log 2>&1

But it's not working. Here my i3.log :

    $ cat .i3/i3.log 
27/08/2013 13:00:58 - CORE DUMPS: You are running a development version of i3, so coredumps were automatically enabled (ulimit -c unlimited).
27/08/2013 13:00:58 - CORE DUMPS: Your current working directory is "/home/hedy".
27/08/2013 13:00:58 - CORE DUMPS: Your core_pattern is: |/usr/lib/systemd/systemd-coredump %p %u %g %s %t %e

deciding for version 4 due to this line: # i3 config file (v4)

Here my i3 config file :

 # This file has been auto-generated by i3-config-wizard(1).
# It will not be overwritten, so edit it as you like.
#
# Should you change your keyboard layout somewhen, delete
# this file and re-run i3-config-wizard(1).

set $mod Mod4

# Font for window titles. Will also be used by the bar unless a different font
# is used in the bar {} block below. ISO 10646 = Unicode
#font -misc-fixed-medium-r-normal--13-120-75-75-C-70-iso10646-1
# The font above is very space-efficient, that is, it looks good, sharp and
# clear in small sizes. However, if you need a lot of unicode glyphs or
# right-to-left text rendering, you should instead use pango for rendering and
# chose an xft font, such as:
font xft:DejaVu Sans Mono 11px
#font xft:cure 8
#font pango: Tamsyn 10px
#font pango:terminus 10px
#font pango:droid sans 12px
#font pango:Inconsolata 13px
