Problem on new Ubuntu 22.04

[davidng]

Please help, I have try everything, even switch to a new PC, still can not solve the
install the driver, displaylink ok, after reboot, not working.
then I have to uninstall, and re-install, then ok, but after reboot, not working again.

after not working, I run displaylink report tool, log attached.
note, above log, was using apt install via synaptics-repository-keyring

---------

I am on fresh install proxmox 7.4-17 with Linux kernel 5.15.116-1-pve
the displaylink device is the same in the first post of this thread.
it plug into a usb3 and passthrough to the below VM.
vm config in below attachment

----------

from post
https://displaylink.org/forum/showthread.php?t=67372
I now know,
1 linux version
2 kernel version
3 displaylink driver version
4 evdi version
are linked, and kernel update fast, and displaylink driver need some time to deploy the new driver to match those new kernels.
so never use "apt update && apt upgrade"


----------

so now I use old stuff,
1 download ubuntu-22.04.1-desktop-amd64.iso

2 downgrade the kernel to 5.15

apt list --installed | grep linux-image
sudo apt remove linux-image-6.2.0-34-generic
sudo apt install linux-image-5.15.0-43-generic

3 download the "DisplayLink USB Graphics Software for Ubuntu5.6.1-EXE.zip"
or "DisplayLink USB Graphics Software for Ubuntu5.6-EXE.zip"
from https://www.synaptics.com/products/d...wnloads/ubuntu

4 install the driver
unzip "DisplayLink USB Graphics Software for Ubuntu5.6-EXE.zip"
chmod +x displaylink-driver-5.6.0-59.176.run
sudo apt install dkms libdrm-dev
sudo ./displaylink-driver-5.6.0-59.176.run --accept

5 displaylink works
dmsg below attachment

6 after reboot didn't work.
dmsg below attachment

----------

I then try
ubuntu-22.04.3-desktop-amd64.iso
ubuntu-22.04.1-desktop-amd64.iso
ubuntu-23.04-desktop-amd64.iso
with above similar procedure

or


download synaptics-repository-keyring
apt install synaptics-repository-keyring
apt update
apt -y install displaylink-driver


or

git clone https://github.com/AdnanHodzic/displaylink-debian.git
cd displaylink-debian
sudo ./displaylink-debian.sh

all are ok after install the driver, then reboot, then not work, black screen

Any news regarding this? Have exactly the same problem. After installation, external monitor works but after the initial restart, it is not working anymore.

I just did another test,
same display device on the same proxmox.
but VM changed from ubuntu 22 to win10, and restart vm and display link device works.
so I guess they just don't like to fix the proxmox vm restart issue on ubuntu.
