<pre>Oh, right. Back when I got the new graphic card, I thought I could do without
it so I didn't install it.
Installing this solves the errors in Xorg.0.log and the dual monitor issue.
The Debian wiki [2] says :
<span class="quote">> Proprietary, binary-only firmware (aka microcode) was removed from the

I just added a mention to dual display.
In fact I spent quite some time searching for a 2nd hand card that wouldn't
need proprietary drivers, and I thought this one would work with just the
radeon driver (as per the feature support table [1]). I must have missed
something.
Thanks and sorry for the noise.
