Those directions state that they are only for specific models of AMD GPUs: "For support of Radeon R9 200, Radeon R7 200, Radeon HD 8000, Radeon HD 7000, Radeon HD 6000 and Radeon HD 5000 series GPUs" The Radeon HD 4250 is part of the Radeon HD 4000-series, which is not in that supported list. In wheezy, there was a separate fglrx-legacy-driver package, which included support for older graphics cards - including the Radeon HD 4000 series. It was available from the wheezy-backports repository. Although this package is still mentioned in the description of the fglrx-driver package, it does not seem to be available anymore - at least not as far as I can tell at a glance. I have a laptop which also has a 4000-series Radeon GPU, and I run it with the non-proprietary driver from the xserver-xorg-video-radeon package instead. It's not as performant as the proprietary FGLRX equivalent would probably be, if one were available, but it does work; the proprietary driver went away in testing some time last year, and I haven't had any particular problems with the free alternative. The directions on that Wiki page should probably explicitly state that other models are not supported by the available proprietary drivers, and suggest the free driver instead. It may not work ideally well, but it should still work. Alternatively, it _should_ be possible to install the most recent FGLRX legacy driver from AMD's upstream site - but that would lose the advantages of the Debian packaging and the integration which it provides, and the directions for accomplishing it with certainty would be considerably more complicated than what's already on that Wiki page. > Why?

Most likely because the 4250 graphics adapter is not supported by the installed driver. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
