bonjour à tous .
pardon pour le dérangement .
voilà , je m’adresse à vous parce que depuis quelques semaines maintenant , le bureau gnome est inutilisable sur debian testing .
seul fonctionne gnome flashback .
le bureau gnome se lance puis l’un de mes 2 écrans s’affiche en grisé puis retour à gdm et impossible de se reconnecter au bureau .
si vous avez une / des idée(s) , je suis preneur .
d’avance merci .
amicalement .
respectueusement .
dany .
Bonjour.
Mis à part d’être devin, je dirais : Wayland cassé ? (c’est un classique)
mais je ne peux strictement rien affirmé
comment tu t’y prends pour confirmer cette idée ?
as tu des pistes de dépannage ?
des commandes à lancer pour commencer ?
je n’ai rien touché .
apparemment , c’est une m.a.j. qui a cassé le bureau …
je n’ai pas confiance en chatgpt
vous pouvez m’aider ?

d’après chatgpt :
gnome-shell → 49.5
mutter / libmutter → 49.4
mismatch mineur mais critique
voilà ce qu’il propose :
sudo apt install mutter=49.5-1 libmutter-17-0=49.5-1 gir1.2-mutter-17=49.5-1
données récoltées depuis gnome - flashback
C’est le jeux ma pauvre Lucette, la distribution testing est casse gueule une bonne partie de son cycle de vie, elle est pleinement utilisable lorsque l’on rentre dans la période de gel de la stable.
SI et seulement SI le problème viens de ce mismatch le mieux est de rollback la version de Gnome-Shell avec tous ce que ça implique 
car tu n’aura pas de version au dessus de mutter et de sa lib dans les dépôts de Forky pour l’instant.
chat gpt :
Solution 1 — revenir cohérent (RECOMMANDÉ)Downgrade GNOME Shell :
sudo apt install gnome-shell=49.4-1 gnome-shell-common=49.4-1
Avantages :
qu’en pensez vous @Clochette et @PengouinPdt ?
cela va il dans votre sens ?
quels sont les risques ?
merci .

Non tu es en unstable, donc pas stable 
Il est en testing pas un unstable 
Et c’est un extrait de cat à pété 
qui précise qu’il n’aura pas plus de problème mais justement le hic c’est que je ne s’est pas si le problème est lié à un souci de compatibilité de la partie mutter et gnome-shell.
Chez moi ils sont alignés sur le même numéro de version et de révision mais j’en sais pas plus.
Je dirais à tester ça mange pas de pain, par contre ça dénote que tu ne dois pas avoir apt-listbugs d’installé
