half screen problem

Asked by giulia on 2012-11-12

i've just installed ubuntu 12.04 on my acer aspire one.
every time i turn it on, it displays everything on the top half of the screen with the lower one staying purple.
i've learned a way to temporarily solve the problem, which is to press Ctrl Alt F2 and then tipe sudo service lightdm restart, which solves the problem as long as i am using the computer-.
how can i fix it permanently,whithout having to do this everytime i turn the pc on?
