You are lucky that you managed to start a desktop, for most people the
fglrx driver just freezes the PC at KDM start. It does so for me, and
I have the same graphic card than your wife's PC.

Well, yes, see this bug report:

The only possibility is to use the free Radeon driver for now and
either disable the desktop effects or only have a minimal set of
effects by using the XRender compositing and wait till ATI provides a
working fglrx driver :(
