Après vérification, les drivers ne sont effectivement pas dispos en Sid.
Eh bien compilons ! (Le .run d’ATI est merdique ?)
J’ai toujours défendu la théorie selon laquelle le temps n’est pas euclidien. Surtout en informatique, et encore plus lorsqu’il s’agit de l’une de mes décisions.
EDIT : Rooh mais ! Ça ne pouvait pas se passer sans problème. J’ai bien suivi les commandes données, puis j’ai installé les .deb par l’installateur de .deb (qui ne m’a sorti aucune erreur). J’ai modifié le xorg.conf :
[code]Section "Device"
Identifier "ATI"
Driver "fglrx"
EndSection
Section "Screen"
Identifier "Default Screen"
DefaultDepth 24
EndSection[/code]
et redémarré. Et là, c’est le drame. L’habituel message selon lequel Xorg n’a pas pu démarrer, et qu’il attend d’être configuré correctement s’affiche. Je me suis donc empressé de remettre en place mon ancien xorg.conf, et de revenir pour me plaindre 
Voici le Xorg.0.log :

Le “segmentation fault” ne me paraît pas de très bon augure 
Je peux aussi éventuellement ajouter la sortie de la compilation (qui contient quelques avertissement, et même une erreur, si je ne m’abuse -_-")
EDIT 2 : Premièrement : voici le seul avertissement qui me semblait digne d’intérêt lors de la compilation :
Deuxièmement : les pilotes libres ne fonctionnent plus non plus, à présent.
EDIT 3 : Je vais tenté de suivre cette méthode : coagul.org/spip.php?article444
