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

from post

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
Code:
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

I then try
