I'm a new user of ubuntu, and it runs really good on my home computer, but I just installed it on a laptop (Acer travelmate 5735Z), and right when I get to the login, the backlight on the screen turns off, which makes it really hard to see anything.

Since I'm completely new in this, it would be nice if some of you could help me, and with as many details as possible on how to do it...

Hope to hear from some of you
