How to try fglrx driver

[Linda]

I am having trouble getting teamviewer to start at boot and 
from reading the logs and doing some searches it sounds like 
it is a video/x windows issue.
The machine has integrated graphics and shows it is the ATI 
Radeon Xpress 200  which from what I can find can use the 
fglrx driver.
I downloaded the fglrx package with synaptic
My problem is that software updater does not give me any 
choices under additional drivers. Can someone point me in 
the right direction on how to try the fglrx driver to see if 
it solves the issue?
               Thank you
                   Linda
