[displaylink] echec de la compilation du driver

[genesis]

bonjour,

J'ai recemment fait l'acquisition d'une docking station avec un chipset displaylink pour utiliser sur mon portable sous arch.
J'ai donc suivi ce tuto : https://wiki.archlinux.org/index.php/DisplayLink
mais l'installation de xf86-video-fbdev-for-displaylink echoue avec un code erreur :

Code : Tout sélectionner

In file included from /usr/include/xorg/globals.h:8:0,
                 from /usr/include/xorg/opaque.h:34,
                 from /usr/include/xorg/xf86_OSproc.h:127,
                 from fbdev.c:14:
/usr/include/xorg/extinit.h:107:38: fatal error: X11/extensions/XResproto.h: No such file or directory
compilation terminated.
make[2]: *** [fbdev.lo] Error 1

Effectivement je n'ai aucun fichier XResproto.h dans /usr/include/X11/extensions/
Il semble que le probleme soit évoqué ici :
https://bugs.archlinux.org/task/32146
ou il est question d'un patch du configure.ac file envoyé a xorg-devel....

[FoolEcho]

Salut,

Code : Tout sélectionner

$ pkgfile XResproto.h                                                                      
extra/resourceproto

La dépendance manque donc au PKGBUILD (peut-être faudrait-il xorg-server-devel d'ailleurs...).

[genesis]

merci pour ta réponse FoolEcho
Je ne connaissais pas la commande pkgfile, bien utile...
J'ai installé resourceproto correctement, la compilation de xf86-video-fbdev-for-displaylink passe "autogen.sh" mais plante sur le "make", comme suit :

[FoolEcho]

Il faut sans doute que tu utilises les sources les plus récentes de fbdev (cf. version des dépôts officiels) et donc que tu modifies le PKGBUILD en conséquence (le "numéro" de version de ce PKGBUILD étant pour le moins... heum... fantaisiste ).

Y-a-t-il d'autres sources pour fbdev ?

donc il voit bien le docking station usb displaylink (17e9:02ea) mais j'ai l'impression qu'il ne le reconnait pas comme une carte graphique. Il me semble que je devrais voir /dev/fb0 ou /dev/fb1 dans dmesg, non ?
Bon, dehors c'est le déluge mais la je seche totalement

[FoolEcho]

Ceci étant, à moins que les modifications aient été incorporées depuis, les sources de freedesktop.org ne sont pas celles, patchées, que le PKGBUILD voudrait... et si ces dernières ne sont pas/plus maintenues, faudra trouver autre chose...

[genesis]

j'ai trouvé ceci :
http://libdlo.freedesktop.org/wiki/DeviceQuirks

Je crois que c'est la solution, en effet mon docking station est bien vu comme un cdrom, (dans dmesg des messages précedents), a priori pour que windaub puisse le monter et installer les drivers automatiquement (livré sans CD).
Je vais donc essayer ca dés que possible et je vous tiens au courant de la suite

[genesis]

bien, ca avance. Aprés avoir créer la regle udev le moniteur s'allume ! vert
mais le libdlo-test1 affiche bien des carrés de couleurs sur le moniteur.
Donc soyons positif, la carte graphique displaylink est bien reconnu via USB et le bon driver est chargé.
Reste a adapter ma configuration xorg pour finir tout cela en beauté. Je posterai la conf dés que possible.

[genesis]

donc maintenant le docking station est bien connecté, le test libdlo-test1 m'affiche bien toutes sortes de jolis carrés de couleurs sur l'écran. Je passe a la configuration de xorg ! comme je m'y attendais : la galèeeeeere...

Evidemment, cela ne marche pas. J'ai bien l'ecran (moniteur) interne de mon laptop fonctionnel mais toujours l'écran bleu immuable coté displaylink (le test libdlo-test1 affiche finalement un ecran bleu.
merci encore pour votre aide !

Quoi qu'il en soit, il ne faut plus utiliser de xorg.conf pour utiliser au mieux la détection automatique mais mettre toute personnalisation dans /etc/X11/xorg.conf.d/.

merci,
J'ai supprimé le fichier xorg.conf et j'ai crée plusieurs fichiers (01-files.conf / 02-modules.conf / 04-inputdevices.conf / 15-devices.conf / 15-monitors.conf / 20-screens.conf / 30-serverlayout.conf) et voici un extrait de /var/log/Xorg.0.log :

visiblement il y a pas mal d'erreurs avec le module fbdev. Que puis je changer dans ma configuration pour corriger ces erreurs ?

Tu peux oublier files, modules et inputdevices.
Et te concentrer sur devices, monitors... et peut-être screen (mais devices en priorité).

Sinon, je ne sais pas pour displaylink (peut-être un Matchquelquechose plutôt que le BusId...).
Le log en entier peut-être ?
