U3DUALHDMIDOCK HDMI don't work

Hello,
I’m a newbie on Parrot (4.10).
I’ve been on ubuntu for years, but I wanted to change to a system that seems more reliable.
I have two AOC screens, one plugged on the laptop (ThinkPad P14S), the other on a Dock (I-Tec USB 3.0/USB-C Dual HDMI)
I installed the driver created by the manufacturer (I-Tec) for Ubuntu (There are no other debian drivers…)
The hard drives, keyboard and mouse were recognized immediately but not the second screen plugged into the dock’s HDMI socket.
I installed 3 systems on my ThinkPad (Ubuntu, Kubuntu and Parrot). The screen works with both Ubuntu systems but it is not recognized under Parrot.
Can someone help me connect the second screen via the dock?
I use an online translator, so sorry if the expression is approximate…

hello,

sudo apt install hdmi2usb-mode-switch :wink:

Thanks,
I’ll try it tomorrow evening

I understand tit’s a little more complicated than a simple command line, I see…
I’m going to have to find a manual, translate it…
I think it’s going to be a long way…
I’m probably not ready for this type of OS yet (I work in the day).
Thank you anyway

Could someone help me install the dock and screen ?
(or tell me where to go…)
I used hdmi2usb-mode-switch help but it’s just incomprehensible to me

Parrot Mate ou KDE??
As tu mis a jour ton system sudo parrot-upgrade ?

essaye d installer sa sudo apt install hdmi2usb-mode-switch et regarde si ton ecran est reconnu si c est le cas soit tu fais un mode mirroir ou tu positionne l ecran que tu veux choisir

redemarre ton systeme avant de verifier si ton ecran est reconnu apres avoir installer le package

Oups tu l avais deja installé je crois non?

did moi ce que c est ton deuxieme ecran exactement

Je suis sur MATE. Mises à jour effectuées
J’ai 3 systèmes sur mon ordi.
Voici ce que me donne xrandr sur Kubuntu
$xrandr

Les deux écrans HDMI (un direct sur le ThinkPad P14s, l’autre sur le Dock) sont des AOC 23.6" LED - 24B1XH

find /sys/devices/ -iname edid

sa c est la commande pour voir si tes ecrans sont reconus par le systemes
tu devrais avoir un retour du genre :

/sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-LVDS-1/edid
/sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-VGA-1/edid

Désolé pour la lenteur des réponses… ma semaine ve ^etre compliquée, je répondrai quand ce sera possible.
└──╼ $find /sys/devices/ -iname edid
/sys/devices/pci0000:00/0000:00:08.1/0000:07:00.0/drm/card0/card0-HDMI-A-1/edid

/sys/devices/pci0000:00/0000:00:08.1/0000:07:00.0/drm/card0/card0-DP-1/edid

Peut etre une idee en passant sur tes ecrans dans les parametres as tu une option VGA?

Pas d’option vga avec le P14S.
Le Dock est reconnu sur Kubuntu et sur Ubuntu.
Y a-t-il des paramètres que je pourrais récupérer sur les autres systèmes pour avancer avec Parrot ?

Pour Info (je ne sais pas si cela peut aider lorsque je tape (sous Kubuntu) :
