[LightDM] Lightdm doesn't start after using the lightdm-webkit-greeter

[Anubhav Yadav]

Hi list, first post here. I am using debian wheezy 7 64 bit.
I am using lightdm (from debian stable repos). And I compiled the
lightdm-webkit-greeter from source.
(http://packages.ubuntu.com/saucy/lightdm-webkit-greeter)

Here are my /etc/lightdmlightdm.conf settings:

[LightDM]
[SeatDefaults]
xserver-allow-tcp=false
greeter-session=lightdm-webkit-greeter
greeter-hide-users=true
user-session=i3
session-wrapper=/etc/X11/Xsession
[XDMCPServer]
[VNCServer]

(All the other values are commented out and I have skipped them here)

Here is my /etc/lightdm/lightdm-webkit-greeter.conf:

[greeter]
background=/home/neo1691/Pictures/debian.jpg
theme-name=Elegant_revisited
font-name=Inconsolata bold 10
webkit-theme=Bevel
xft-antialias=true
xft-dpi=96
xft-hintstyle=slight
xft-rgba=rgb

When I start my laptop, it just goes to a black screen with a small
cursor blinking
instead of starting lightdm.

Here are the log files:

Here is the output of /var/log/lightdm/x-0-greeter.log

Now the output of x-0.log

If I run the lightdm-webkit-greeter command from cli, it opens up the
sweet interface in a gtk window with some warnings on the terminal.

I also installed plymouth package, just to let you all know, after finding
an error relating to this in the lightdm.log file.

If you have reached till here, I appreciate you for your time and effort
for reading such a long post! Any help would be really appreciated.

Cheers!
