[RESOLUT]15.04 touchpad asus non reconnu
RÉSOLUT suivre lien du dernier poste
Bonjour!
Je possède un asus K751L sur lequel j' installé ubuntu 15.04
Le problème est que mon touchpad semble être reconnu comme étant une souris et par conséquent je ne peut pas scroller
le scroll deux doit fonctionne sous W$
Parametre -> souris et pavé tactile ne me donne pas l'onglet "touchpad"
un xinput list renvois
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ PS/2 Logitech Wheel Mouse id=16 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Video Bus id=8 [slave keyboard (3)]
↳ Sleep Button id=9 [slave keyboard (3)]
↳ USB Camera id=13 [slave keyboard (3)]
↳ Asus WMI hotkeys id=14 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=15 [slave keyboard (3)]J ai essayé sans succès les solutions de cette page: https://doc.ubuntu-fr.org/touchpad_asus
Cette page étant assez ancienne j ai espoir que quelqu’un a depuis trouvé une solution
Merci d'avance pour votre aide!

Re : [RESOLUT]15.04 touchpad asus non reconnu
Rien n'a fonctionné, et
xinput list "$(egrep -i 'synap|alps|etps' /proc/bus/input/devices |cut -d'"' -f2)" renvois unable to find device

Re : [RESOLUT]15.04 touchpad asus non reconnu
Tu as essayé Fn+F9 pour activer le touchpad ?
As-tu une souris branchée sur ton ordinateur ?

Re : [RESOLUT]15.04 touchpad asus non reconnu
Fn F9 ne bloque même pas le touch pad, et je fait toutes les manips sans souris autre que le touchpad

Re : [RESOLUT]15.04 touchpad asus non reconnu
Résolu ici https://bbs.archlinux.org/viewtopic.php?id=124710 Sauf que c'est pour Arch...
Mais si on lit les commentaires, on trouve ce lien http://superuser.com/questions/619582/r … g-in-linux
Et l'on remarque que c'est pour Debian Jessie. Bonne nouvelle. 
Il n'y a plus qu'à suivre la manip donnée en espérant que ça passe pour ubuntu.
wget http://datacompboy.ru/psmouse-elantech-v7right.tar.bz2
tar xfj psmouse-elantech-v7right.tar.bz2
sudo mv psmouse-elantech-v7right /usr/src/
sudo dkms install -m psmouse -v elantech-v7right
sudo modprobe -r psmouse
sudo modprobe psmouseAffaire à suivre...
Edit : Si vous rencontrez des soucis avec le clic droit, il faut modifier le fichier psmouse-elantech-v7right/src/elantech.c.orig avec un éditeur de texte et remplacer
__clear_bit(BTN_RIGHT, dev->keybit);par
//__clear_bit(BTN_RIGHT, dev->keybit);C'est à la ligne 1022.

Re : [RESOLUT]15.04 touchpad asus non reconnu
Toutes les commandes sont bien passées ?
Pourtant ça a également fonctionné sur Linux Mint 16 avec un Asus B400A... Touchpad reconnu comme une souris mais encore différent ?
Tu as aussi bien sûr essayé gpointing-device-settings ?
Sinon peut-être tu devrais tenter avec un kernel plus récent (> 4.0), genre le 4.1.4... Puis réinstaller le correctif ci-dessus par dessus.

Re : [RESOLUT]15.04 touchpad asus non reconnu
Bonjour,
sur asus x751ma-ty182h la solution est ici voir si cela marche pour des futurs acquéreurs d'asus.
