Do you have an ATI card? Maybe a HD4xxx or lower? And you used to have the proprietary drivers (fglrx). Well, this setup won't work anymore (bug).

Unfortunatly, amd considers these cards legacy and they don't receive as much love as they deserve anymore. Remove the proprietary drivers (sudo apt-get purge fglrx*) and reboot to use the opensource drivers.

Try this:

sudo apt-get install --reinstall lightdm

If that does not work, try:

sudo apt-get install gdm

And when asked, select gdm.

did you use proprietary graphic drivers before upgrading? if so, there might have been some upgrade problem. try to reinstall them following the appropriate instructions at

If not, try issuing the command

grep EE /var/log/Xorg.0.log

this should show the errors and hopefully the cause of your problems. add that to your problem in order to better understand what's the issue.
