Bug Description

Adding the display-setup-script parameter to /etc/lightdm/lightdm.conf results in LightDM not being started correctly (black screen, X-cursor). Did some test runs to confirm that any value specified for the parameter triggers the described behavior.

$ cat /etc/lightdm/lightdm.conf
[SeatDefaults]
greeter-session=lightdm-gtk-greeter
greeter-hide-users=false
user-session=xubuntu
display-setup-script=sh -c 'echo 123 > /dev/null'
$
$ apt-cache policy lightdm
lightdm:
  Installed: 1.4.0-0ubuntu4
  Candidate: 1.4.0-0ubuntu4

Can confirm this happens to me when intalling numlockx
and adding
greeter-setup-script=/usr/bin/numlockx on
to /etc/lightdm/lightdm.conf

$ cat /etc/lightdm/lightdm.conf
[SeatDefaults]
user-session=ubuntu
greeter-session=unity-greeter
greeter-setup-script=/usr/bin/numlockx on

$ apt-cache policy lightdm

Booting to the greeter sometimes fails and sends me to a black screen and x-cursor.
Once booted, any subsequent logout always goes to a black screen and x-cursor.

I think this was caused by a change in glib that picked up us using the API wrongly. Regression tests picked this up and should be fixed in this commit:
