Title:
  Intermittent black screen or low graphics mode message

Status in Light Display Manager:
  New
Status in “linux” package in Ubuntu:
  Fix Released

Bug description:
  Update - 01.19.13

  Some systems are intermittently booting to a black screen or message
  about low graphics mode but a graphical login display never loads.

  Multiple GPU's are affected. Intel HD graphics driver and ATI open
  source driver are confirmed to have the issue. Nvidia binary driver
  and Nouveau driver still unconfirmed.

  Multiple users are affected here:

  There are currently three known workarounds to this issue:
  1) Log in with CTRL+ALT+F1 and issue command "sudo service lightdm restart"
  2) Add some sleep to /etc/init/lightdm.conf
  3) Install and use GDM instead of lightdm
