Dual ASUS zenscreen External displays not working using i-tec C3DUAL4KDP on Lenovo T15

Hi all,

I have gone through the forum to see if there are any problems that relate to mine but i could not find any, hence the reason for this post, i have just come from windows to Zorin OS so please have a little patience with me :slight_smile:

I have a Lenovo T15 laptop and have been struggling for a couple of days now, trying to get two external Asus zenscreen monitors to work. I purchased a i-tec C3DUAL4KDP adaptor to connect the two screens to the laptop but it is not working or even powering up the screens? So one of my colleagues suggested that i should view the "dmesg" output when connecting the screen up, and what i get is the following output seen below, but i have no idea what else i must do in order to get it working, i have even tried installing the DisplayLink from the Ubuntu site without success, the graphics card that is in the laptop is:

00:02.0 VGA compatible controller: Intel Corporation TigerLake-LP GT2 [Iris Xe
Graphics] (rev 01)
Subsystem: Lenovo TigerLake-LP GT2 [Iris Xe Graphics]
Kernel driver in use: i915
Kernel modules: i915

Output from "dmesg"

You could try a more general websearch using "Iris Xe Graphics ubuntu 22.04", but from what I see so far from doing that myself is not very promising.
(ZorinOS 17 is based on Ubuntu 22.04 LTS.)

Found posts on other forums that it is not supported yet until maybe Ubuntu 22.10. Problems with Intel Iris Xe GPU hardware video acceleration in 22.04 - Desktop - Ubuntu Community Hub

Also find redirects to an Intel page, that talks of OEM kernels. All a bit above my paygrade.
