Driver issues Kubuntu 24.04

[Goldenpantsman]

Hello,

I'm hoping to get some help with my issues.

I am using a Dell USB dock that has DisplayLink, it has been working fine for about a month.

I had the driver installed via APT package.
Yesterday I did a `apt update && apt upgrade` and after restarting, the monitor connected to the dock has no more display.

sudo apt install displaylink-driver

If I try install the driver again from APT, I get an error relating to evdi.


I tried to install from the downloaded package and was able to get that to work (after running an uninstall on a remaining evdi)

I still get no output on my monitor.
Any suggestions?

I'm having issues with Ubuntu 24.04 and kernel 6.8.0-50, but according to the release notes for Displaylink Driver v6.1.0-17, Ubuntu is only supported up to v23.04 LTS so likely we'll just have to wait for support to be extended (no idea when that is).

Hello all,

I revisited my issue in the new year.

I ran this command and now the displaylink driver is working as expected.

sudo apt --fix-broken install

May this help lost souls in the future.
