--- Comment #6 from Jérôme <jerome at jolimont.fr> ---
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 :

> Proprietary, binary-only firmware (aka microcode) was removed from the 
> Debian kernel's radeon DRM driver in linux-2.6 2.6.29-1, to resolve 
> Debian bug 494009.
> The firmware can be provided by installing the firmware-linux-nonfree package.

> Window System.

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.
