Connexion deuxième écran impossible

Support Debian
#1

Bonjour,
Lors de la connexion d’un deuxième écran (TV) celui du PC passe au noir et ne réagit à aucune commande ; je n’ai trouvé aucune rubrique traitant de la config. pour un deuxième écran.

PC Dell sous Debian 11 (5.10.0-20),
carte graphique :

*-display                 
       description: VGA compatible controller
       produit: RV620 LE [Radeon HD 3450]
       fabriquant: Advanced Micro Devices, Inc. [AMD/ATI]

Connectique :sortie carte DMS 59 +adaptateur DMS 59 - 2x HDMI

Merci pour vos suggestions

#3

il faudrait savoir si tu es sous mate,cinnamon,xfce,kde…

la commande recherchée est xrandr

et

tail -f /var/log/
#4

Le bureau est kde Plasma
En connectant l’écran TV sur le port dédié aux PC ( ce qui n’était pas le cas précédemment !!) l’affichage sur l’écran PC est maintenu après la connexion à l’écran TV et lors de la première connexion un bandeau s’affiche donnant la sélection des écrans 1,2, 1&2… en sélectionnant 1&2 : rien sur l’écran TV sauf l’indication « hors standard » ; bizarrement en débranchant/rebranchant la liaison TV, impossible de faire réapparaître à nouveau ce bandeau de sélection ?
Dans le menu « Affichage / écran », » config d’affichage » ne détecte que l’écran PC.
Le pb serait-il coté TV ??
Ci dessous le retour des lignes de commande

xrandr

tail -f /var/log/

tail: erreur de lecture dans '/var/log/': est un dossier
tail: /var/log/ : impossible de suivre la fin de ce type de fichier, abandon sur ce nom
tail: aucun fichier restant
#5

désolé j’ai oublié de mettre le fichier :

il faudrait la différence de xrandr --verbose avec et sans le deuxième écran

et
tu tapes

tail -f /var/log/Xorg.0.log

puis tu branches le deuxième écran et là les lignes qui s’affichent seront la réaction du serveur X à la connexion

PS
tu confirmes que chaque écran marche?

#6

Je confirme que les deux écrans fonctionnent.

Avec l’écran PC seul

$ xrandr --verbose

salut
vu que le xrandr ne change pas , il est « normal » que le deuxième écran ne marche pas .
mais ça semble en contradiction avec Lors de la connexion d’un deuxième écran (TV) celui du PC passe au noir .
tu confirmes que le deuxième xrandr correspond à l’écran tv qui marche mais pas celui du PC?

1er test à faire : changer les fils

#8

Le deuxième écran ne marche pas bien qu’il soit détecté (cf le deuxième xrandr :

DVI-0 connected primary 1920x1080+0+0 (0x55) normal… ).

par ailleurs lors de la connexion l’écran PC ne passe pas au noir (c’était lors de la 1ère manip qui par erreur n’utilisait pas le port sur la TV dédié au PC .

J’ai fait un autre essai avec connexion VGA / VGA entre un portable et la TV : l’écran TV ne duplique pas l’écran PC mais affiche la page d’ouverture de l’ OS utilisé à savoir le logo LM de Linux Mint et je ne vois aucun réglage à faire coté TV une fois le port ad hoc sélectionné ?

#9

Ave le portable sous Linux mint et config de l’affichage dans « Paramètres système / Affichage/ écrans en miroir » j’ai enfin un clonage de l’écran sur la TV, en liaison VGA ou HDMI mais dans les deux cas pas de son sur la TV !
Il y a donc un réglage à faire au niveau de l’affichage sur le PC, mais avec le PC sous Debian/Plasma je ne vois pas ou se cache cette fonction ? Reste aussi la non transmission de la voie son.
