Public bug reported:
This problem started after upgrading Ubuntu 12.10 which worked fine to Ubuntu
13.04. After booting, my Dell inspiron 1420 reaches an all purple screen
without login. Ctrl-Alt-F1 gives a purple screen with
blinking cursor and the words "starting up" Ctrl-Alt-F2 yields a console
terminal where I can access unity with "startx". I needed
to update the Nvidia driver to 319 for "startx" to work.
The /var/log/lightdm/lightdm.log is the following:

I have tried reinstalling lightdm, gdm, ubuntu-desktop, and xserver-xorg as
well as editing the /etc/init/lightdm.
Occasionally one of these changes has caused the login to work once but break
on the following reboot. This
bug is similar but not identical to other reported lightdm bugs. Thank you for
your help.
