This FAQ is in progress.

To help people answering you, please provide result of command:
  sudo lshw -C display

If you get at end a blank screen, have a look at: http://ubuntu-tutorials.com/2010/05/06/ubuntu-10-04-lucid-blank-screen-at-startup-workaround/

If you don't get boot menu, but a black screen, and that after a few times you get login screen, Grub2 is unable to manage properly current resolution of screen. In this case, run command:
   gksudo gedit /etc/default/grub
Remove '#' before line defining screen resolution, then run command
   sudo update-grub
and then reboot
