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 : ```nohighlight *-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 ---

il faudrait savoir si tu es sous mate,cinnamon,xfce,kde… la commande recherchée est `xrandr` et ```nohighlight tail -f /var/log/ ``` ---

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 ```nohighlight xrandr Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192 DIN disconnected (normal left inverted right x axis y axis) DVI-0 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 527mm x 296mm 1920x1080 60.00*+ 50.00 59.94 1920x1080i 60.00 50.00 59.94 1600x1200 60.00 1680x1050 59.88 1280x1024 75.02 60.02 1440x900 74.98 59.90 1280x960 60.00 1152x864 75.00 1280x720 60.00 50.00 59.94 1024x768 75.03 60.00 832x624 74.55 800x600 75.00 60.32 720x576 50.00 720x576i 50.00 720x480 60.00 59.94 720x480i 60.00 59.94 640x480 75.00 60.00 59.94 720x400 70.08 DVI-1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 1600mm x 900mm 1920x1080 60.00*+ 50.00 59.94 30.00 25.00 24.00 29.97 23.98 1920x1080i 60.00 50.00 59.94 1280x1024 60.02 1280x720 60.00 50.00 59.94 1024x768 60.00 800x600 60.32 720x576 50.00 720x576i 50.00 720x480 60.00 59.94 720x480i 60.00 59.94 640x480 60.00 59.94 ``` ```nohighlight 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 ``` ---

désolé j’ai oublié de mettre le fichier : il faudrait la différence de xrandr --verbose avec et sans le deuxième écran et tu tapes ```nohighlight 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? ---

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 ---

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 ? ---

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.
