après de 18-04 LTS vers 20-04 LTS impossible modif. affichage

DCH

Bonjour,
après un upgrade difficile de 18-04 LTS vers 20-04 LTS, ( https://forum.ubuntu-fr.org/viewtopic.php?id=2061333) impossible de modifier "affichage"
Conséquence: mes deux écrans affichent la même image, mais avec définition incorrecte, de même que la taille.
J'ai testé "https://doc.ubuntu-fr.org/radeon", sans succès: je n'ai pas de fichier xorg.conf, et donc si j'en crée un, ça plante (encore!)
machine Acer Aspire PC avec AMD Athlon 64x2, avec carte Radeon HD2400 Pro

J'ai tenté de me débrouiller tout seul: échec
Merci par avance pour votre aide!

Pour info, ayant essayé "doc ubuntu radeon", j'ai regardé ce que générait xorg.conf.new: il me mettait un driver "amdgpu"... quand j'ai remplacé par "radeon" sur le device 1 et recopié le fichier en /etc/xorg.conf, tout a planté...

Pour nettoyer :

Le 11/02/2017, moko138 a écritPour supprimer tous ces fichiers de configuration devenus sans objets et marqués "rc", et uniquement ces fichiers, exécute :

dpkg -l | awk '/^rc/{print $2}' | xargs -r sudo dpkg -P

_ _ _

Montre :

lspci -k | grep -EA3 'VGA|3D|Display'

après cete super purge:

Avec xrandr, toujours la même réponse:

Bonjour
J'ai exactement le même problème. J'ai initialisé un nouveau post pour mon problème... C'est un peu dommage car ça fait doublon, mais bon...
=> https://forum.ubuntu-fr.org/viewtopic.php?id=2061665

Si vous trouvez la solution, svp, pensez à renseigner aussi mon post 😃
Merci

@JMMO59

Il faut changer dans ton code le :

Bonjour et merci pour l'info,
je viens d'essayer, et j'ai modifié mon "10-amdgpu.conf"', mais je n'ai pas de "10-nvidia.conf".
Par contre, j'ai un "10-radeon.conf": où faut-il que je fasse le lien avec le driver radeon? car dans mon post 3, j'ai fait une tentative qui a tout planté!
Pour le moment, j'ai le même résultat qu'avant...

DCH

Et je dois rajouter que
"

default connected 1400x1050+0+0 0mm x 0mm
   1400x1050     77.00*

ne correspond absolument pas aux écrans connectés! confiemation de ce que me renvoit xrandr:

xrandr: Failed to get size of gamma for output default

La remarque :

Le 17/12/2020, Jimmy76 a écritBonjour,
La sortie est en 77Hz ? C'est curieux comme fréquence. Je vais chercher comment modifier ça.
Merci,

Bonjour,

Vu la Doc > § 7 - radeon#problemes_connus

Montre le contenu de :

cat /usr/share/X11/xorg.conf.d/10-radeon.conf.

Bonjour et merci de continuer à me soutenir!

dan@dan-Aspire-M3100:~$ cat /usr/share/X11/xorg.conf.d/10-radeon.conf
Section "OutputClass"
	Identifier "Radeon"
	MatchDriver "radeon"
	Driver "radeon"

Je viens de faire la modif tel qu'indiqué, je reboot

DCH

Après reboot, rien de nouveau.
En m'appuyant sur ta réponse à JIMMO59, je viens de tenter de forcer xrandr. Réponse:

dan@dan-Aspire-M3100:~$ xrandr --newmode $(gtf 1280 1024 60 | sed -ne 's/"//g;s/ Modeline //p')
xrandr: Failed to get size of gamma for output default

Pour info complémentaire, ma machine est en triple boot, et les écrans sont bien reconnus et gérés sous Debian et sous Windows Vista. Je constate également qu'au démarrage de Ubuntu, après le GRUB, les définitions de chaque écran sont déjà défaillantes. Cela peut-il aider?

DCH

En recherchant dans mon pb précédent (https://forum.ubuntu-fr.org/viewtopic.php?id=2061333&p=3), je vois que j'ai fait une modif de mon GRUB en ajoutant: "GRUB_CMDLINE_LINUX="ioapic radeon.modeset=0"
Avant il y avait:"GRUB_CMDLINE_LINUX=" "" je vais tenter...
Je ne sais pas à quoi correspond "modeset=0" et si une autre valeur que 0 changerait quelque chose?

xubu1957

Je n'ai jamais utilisé les parametres_du_noyau (§ 7 de la Doc).

DCH

Manip évoquée #16: échec...
Dans un premier temps, les écrans semblent corrects, le sigle MATE est bon sur chaque écran. Le pb est que la machine n'arrive pas jusqu'à me proposer le mot de passe, et je n'ai pas la possibilité d'actionner VerrNum...
Je viens donc de me remettre comme précédemment.
Je continue de creuser...

DCH

Je viens de me poser une question: ne serait-ce pas ma carte vidéo qui est trop vieille et donc, plus compatible avec Ubuntu 20-04?

dan@dan-Aspire-M3100:~$ lspci -vnn | grep -A 12 '\''[030[02]\]' | grep -Ei "vga|3d|display|kernel"

A priori j'ai les bons drivers:
