1st Way to solve your issue:
Try to reconfigure lightdm (if it doesn't solve your issue then go for Alternate way mentioned below.)
Open terminal(CTRL+ALT+T) and execute following command:
sudo dpkg-reconfigre lightdm
Then chose lightdm
from the list. As shown below:

Restart your system:
sudo reboot now
It should fix your issue.
an alternate way, which would solve your issue. Give it a try.
Installing a new display manager can fix your problem. Steps to install GDM(a display manager much like lightdm):
Open terminal(CTRL+ALT+T) and execute following commands:
sudo apt-get install gdm
sudo dpkg-reconfigure lightdm
then chose gdm
from the list:
(source: akamaihd.net)
sudo reboot
If it's still not fixed, try removing lightdm
after installing gdm
:
sudo apt-get remove --purge lightdm
sudo reboot

If you are booting windows with ubuntu i have same problem then i tried everything referred from sites.finally nothing is worked for me.
so one thing is worked for me.
this will boot your ubuntu os normally. and it works for me also it saves your time to everytime restart lightdm service.
