Écran tactile désactive l'entrée clavier

Sieger14 · Le 21/08/2021, à 11:04

Bonjour à tous,

Voici mon problème :

On m'a offert un ordinateur à écran tactile rabattable sur lequel je me suis empressé d'y installer Ubuntu. En fait, on peut rabattre l'écran derrière le clavier pour le mettre en "mode tablette". L'action désactive le clavier pour éviter des entrées accidentelles. Jusque ici, pas de problème.
Cependant, lorsque que je mets la machine sous tension, l'entrée clavier ne fonctionne pas lorsque j'essaie de me connecter au compte utilisateur. Je pense que l'ordinateur se met en mode "tablette" au démarrage, le clavier est donc désactivé.
J'ai le dual-boot avec Windows d'origine, et tout fonctionne sur ce dernier (normal c'est d'origine).

J'ai trouvé quatre solutions temporaires à ce problème :

rabattre l'écran en mode "tablette" puis le remettre normalement, ce qui réactive le clavier. Temporaire car je pense que les charnières vont fatiguer plus vite que prévu si je fais cette action à chaque démarrage... Et puis on a l'air fin lorsqu'on est dans le train...
se connecter avec l'écran tactile et le clavier visuel (peu commode lorsqu'on est pro bonnes vieilles touches physiques)
mettre la machine en veille, puis sortir de veille
attendre, au bout d'un certain temps variable, le clavier se réactive

N'ayant pas utilité de l'écran tactile, j'ai donc tout bêtement décidé de le désactiver. J'ai utilisé cette procédure :

Créer un fichier permanent dans le répertoire approprié

sudo gedit /etc/profile.d/touchscreen.sh

Indiquer dans le fichier la commande à executer à chaque démarrage (désactiver le périphérique écran tactile "Wacom HID 486B Finger touch")

#!/bin/bash
xinput -set-prop "Wacom HID 486B Finger touch" "Device Enabled" 0

Cette méthode ne désactive l'écran que lorsque la session utilisateur est ouverte. Dans mon cas, j'ai besoin du clavier lorsque que la session n'est pas ouverte pour entrer le mot de passe utilisateur.

J'ai donc farfouillé dans le bios une option qui permettrait de désactiver l'écran tactile avant même le lancement de l'OS, ce que j'ai trouvé. L'écran tactile est bien désactivé sur la page de connexion utilisateur mais... le clavier ne fonctionne toujours pas...

Voilà où j'en suis actuellement.

Merci pour votre temps et pour toutes vos éventuelles idées ou solutions !
