Le 11.10, ma résolution maximale autorisée est de 1024x768, alors que mon moniteur prend en charge 1280x800 sous Windows.
J'ai déjà vu une méthode pour résoudre ce problème via xrandr, mais je reçois toujours un message disant qu'il n'atteint pas la taille du gamma.
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 1024 x 768, maximum 1024 x 768
default connected 1024x768+0+0 0mm x 0mm
1024x768 61.0*
800x600 61.0
640x480 60.0
Existe-t-il un autre moyen d’ajouter une résolution 1280x800 à mon ordinateur portable? Y a-t-il une solution de contournement?
Merci d'avance.
J'ai remarqué que votre résolution maximale indiquée dans xrandr était limitée à 1024x768. D'abord, vous pouvez peut-être suivre le wiki ci-dessous et essayer de forcer X à reconnaître la RAM vidéo.
c'est-à-dire mettre de nouvelles lignes dans /usr/share/X11/xorg.conf.d/99-vesahack
.
Une fois que le max a été modifié avec succès après un redémarrage, vous pouvez passer aux étapes suivantes, par exemple --newmode
et --addmode
, etc.
J'ai eu ce problème lors du débogage de mon pont de lierre. Je pense que cela pourrait être la raison de votre erreur "Impossible d'obtenir la taille de gamma".
Vous devez ajouter un modeline dans votre fichier Xorg.conf. Veuillez lire ceci: http://www.x.org/wiki/FAQVideoModes La partie sur powerstrip peut être intéressante car vous avez des fenêtres qui fonctionnent avec la résolution correcte.
Faites une sauvegarde de /etc/X11/xorg.conf et ajoutez les lignes ci-dessous.il a fonctionné pour moi pour OEL6.5
