No external monitorvia USB-C over Dockingstation
#1
Hi @all,

i'm not totally new to Ubuntu/Linux but still far from being a pro!

Actually i run Ubuntu 22.04 (installed via ARMBIAN) with Gnome 42 on my Pinebook Pro:

Code:
$lsb_release -a
    No LSB modules are available.
    Distributor ID:    Ubuntu
    Description:    Ubuntu 22.04.2 LTS
    Release:    22.04
    Codename:    jammy
       
    $ uname -a
        Linux pinebook-pro 6.1.30-rockchip64 #3 SMP PREEMPT Wed May 24 16:32:53 UTC 2023 aarch64 aarch64 aarch64 GNU/Linux
    $ gnome-shell --version
     GNOME Shell 42.

I've tried an Dell Monitor with USB-C-Support (U3421WE) an DELL-USB-C- Dockingstation with a Lenovo-Monitor and a Lenovo Thinkpas Universal USB-C-Dock (40AY) with an Fujitsu Monitor.

 
The beahviour ist always the same: USB-Hub is Working (Mous, & Keyboard etc.) but Display is not:

The U3421WE display,: " No USB-C Signal from the Divce". The other ones yust say: "No input Signal".
It makes no difference if it is hotplugged or plugged in befor boot also not flipping the USBC plug.

Her ist (as an example from the setup with the DELL.Monitor on the Lenovo-Dockingstation) some information i imagine to be helpful:

I have also already read through the existing thread on the subject of USB monitor (https://forum.pine64.org/showthread.php?tid=10206) but did not notice a decisive hint. Or I did not recognize it...

Furthermore, I have already asked at ask-ubuntu, but got no response there.
