@Adrienne-
It sounds like the problems you're experiencing more specifically relate to either of these two bug reports ("backlight off at startup"):
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/779166
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/765438
My suggestion is to try the new 'inverted-backlight' test PPA, but post your results to bug 779166:

Important: Booting with the parameter "acpi_backlight=vendor" may also be necessary -- see the inverted-backlight page above for details.
