When Ubuntu starts up, the back-light is off on my laptop. I can plug it into an external monitor and the display is fine. I can easily turn the back-light on with "sudo setpci -s 00:02.0 F4.B=[HEX]" where 00 is the brightest and FF is off. In past distributions, the GUI-based brightness utilities did not work and I used this command to change by back-light brightness. I know that there are many people who can not use back-light GUI-utilities on the past distributions as well.
