Je suis actuellement sous Ubuntu et devant l’instabilité et le coté ‘windows’ grandissant j’ai réservé une partition pour essayer Debian…
Le premier jour j’installe une Lenny tout fonctionne bien (compiz en particulier) mais je trouve la distrib un peu vieillotte…
Le lendemain, je m’aperçois que dans la nuit la nouvelle stable a changée 
, très content de la découverte je formate en ext4 et pose une squezze neuve…
Aiiie, quelle déception compiz n’est plus au rendez-vous… Je m’en sers beaucoup, c’est devenu important pour moi… Je me débat, googlise à tour de bras, copie-colle, installe etc… rien n’y fait…
Le pire est que tout semble être en place…
invariablement je tombe sur ces trois lignes…euh quatre…
[code]~$ compiz --replace

compiz (core) - Error: Failed to manage screen: 0
compiz (core) - Fatal: No manageable screens found on display :0.0
Launching fallback window manager[/code]
Avec /apps/metacity/general/compositing_manager on ou off
Ci-joint tout ce que j’ai pu lire sur les forums pour vous aider à m’aider… (j’ai un peu nettoyé les réponses mais en faisant gaffe)
