you will find several packages. Among these are

that you mentioned you lacked earlier. It is a driver without X
support, but it seems the X driver depends on it. You probably also
want fglrx-amdcccle_14.501-0ubuntu1_amd64_UB_14.01.deb, which is the
graphical setup utility. There is also a development package for
OpenGL, which you may or may not want.

But. These packages are for *Ubuntu*. Ubuntu is not Debian. Yes, they
both use .deb packages, but that does not mean that the Ubuntu packages
will work well (or at all) on Debian. Personally, I have no idea, as I
haven't tried, but I would take a backup first, as they may hose things


You will find a .zip file of all the drivers and the setup utility for
all Linux x64 systems - that is an alternative way of installing them.
Maybe that is a better approach on Debian, I really don't know for
sure. I am sure Google has some insight on this, I would also check the
Debian wiki.

First, read this page;

It contains instructions for how to use these drivers on a Debian
system. There is even a section there on multiple screens.

See above.

By "the other", you mean the AMD one? Or do you have problems with the
nVidia thing too?

Many people run Debian on laptops with external monitors, so it should
be possible to get it to work. The problem in your case seems to be
that the GPU is only supported by AMD's driver. If you can install
that you should have better luck.

It is also *possible* that your GPU would be supported by a newer
version of the "radeon" (open-source) driver, I do not know. Maybe one
is available in backports.
