I'm seeing this same issue running OpenSUSE 13.1 inside of VirtualBox (4.3.6 r91406 on Mac OS X 10.6.8) with lightdm and xfce. This uses vboxvideo rather than the intel video driver.
The first time the virtual machine boots after the install process lightdm starts fine. At each reboot after that, lightdm fails.
x-0.log states the X Server terminates after loading GLX.
x-0-greeter.log states that lightdm-gtk-greeter could not open the X display
Once I flip to a terminal (cntrl-alt-f5) I can start the X server or lightdm from the command line and everything works fine.

Using lxdm rather than lightdm works fine.
