I'm no expert but here are a few things I've gleaned from reading posts
here...

There is a problem with Intel video - they haven't produced linux drivers no
released the code so others can do so. There are work-arounds, but I can't
recall what.

I'm assuming you have used the Hardware Drivers applet. There is another
utility called Envy which will semi-automate the installation of both ATI
and Nvidia video cards. It's in the repositories.

There are no easy answers to display problems, except perhaps (for desktops)
to change the video card to one that is better supported. For laptops you
are stuck with what came built in but perhaps it might be supported by
another distribution. Look into what's available from
http://distrowatch.com/ and keep trying. That's not a great answer, but this
is linux not windows. While we have an amazingly inventive community of
software engineers there are some things that haven't been fixed and may not
be for a while. After all this is free software and there have to be a few
disadvantages to that - but nothing compared to the advantages of a superior
operating system with iron-clad security.

Good luck, don't give up, keep searching and trying out every possible
alternative until you find one that works - and keep us posted. You are not
alone.
