Voila ce que j’ai trouvé en faisant une petite recherche :
[quote]Some notes for debian users:
The debian Linux distribution in most cases does not come with the
ability to handle rpm packages with the rpm tool. But there is a
tool called “alien” which allows you to convert rpm files into the
debian supported *.deb package format. Please consult your debian
documentation on how to operate this tool.
A typcial debian installation commandline will look like this:
dpkg -i <ati_package_name>.deb
In order to override complaints (which might be caused by an already
installed package “xlibmesa3” that also provides the file libGL.so.1.2)
please use this installation command line:
dpkg -i --force-overwrite <ati_package_name>.deb[/quote]
Si ca peut aider du monde !
PS : vous pouvez trouver les drivers (en rpm) sur mon compte free http://gromez.free.fr/radeon/
