Bonjour tout le monde.

Je viens de mettre a jour un ordi de fedora 20 à fedora 21 (via yum). Tout semble fonctionner a l'exception du pilote 32bit de la carte graphique (AMD Radeon HD-6870). Le pilote 64 bit fonctionne sans problème lorsque je l'ai testé avec 0.AD .
Pour ce qui est de steam, en 32 bits, j'obtiens dans le terminal:
$ steam

ce lien ne contiens pas la solution du problème.

J'ai pas mal écumé les forums mais je n'ai pas encore trouvé de solution a mon problème. Quelqu'un sait-il d'où ça peut venir ou comment le résoudre?

En débranchant la carte graphique pour utiliser le GPU intel du processeur je n'ai plus ce problème, il vien donc bien du pilote "radeon".
Depuis mon premier post je suis passé à une installation "propre" en formatant la partition mise à jour mais j'ai les mêmes problèmes.
Faut installer les bibliothèques mesa en 32 bits. Je regarde cela plus tard, il faut aussi refaire la liaison de certaines bibliothèques.
j'ai installé tout les paquets 32 bit ayant mesa dans le nom, dans le doute, mais sans succès. Par contre pour ce qui est de refaire la liaison dans les bibliothèque je n'ai pas trouvé d'info.
En regardant bien ça doit être sur le forum. Je regarde de mon coté.

Après c'est fort possible que ce soit un bogue, perso j'en ai pas sur la rawhide.
un mois plus tard
J'avais temporairement lâché l'affaire mais je m'y suis remis depuis la sortie de fedora 21 beta.
Le problème viens des runtimes inclus dans steam. Après avoir supprimé les fichier suivants, tout rentre dans l'ordre.
rm ~/.local/share/Steam/ubuntu12_32/steam-runtime/i386/usr/lib/i386-linux-gnu/libstdc++.so.6
rm ~/.local/share/Steam/ubuntu12_32/steam-runtime/i386/lib/i386-linux-gnu/libgcc_s.so.1
Idem pour un autre jeu, Heroes of Newerth où il faut supprimer libgcc_s.so.1 et libstdc++.so.6 depuis /HON installation folder/libs-x86_64/
2 mois plus tard
Merci pour la solution pyrignis, il faudrait la rajouter sur le wiki.
Bonjour à tous,
dans mon cas, le fait de supprimer/déplacer ces deux bibliothèques ne résout pas le problème.
Steam ne se lance plus si je supprime le
libstdc++.so.6
et si je la laisse, j'ai le popup avec l'erreur d'OpenGL.

Voici les erreurs avec la bibliothèques supprimées:
