Today after running the following command: sudo apt update && sudo apt upgrade -y the held back kernel 6.8.0-40-* were updated and moments later my AOC usb monitor stopped working. I decided to reinstall display link latest driver for ubuntu 6.0.0-24 and received the following: sudo ./displaylink-driver-6.0.0-24.run Verifying archive integrity... 100% MD5 checksums are OK. All good.

But this the results of updating the kernel to 6.0.0-24 please advise. Myles
I resolved the issue. I am thinking the new kernel includes the latest evdi. After researching I decided to remove the multiple evdi's, rebooted ubuntu 22.04.4 LTS laptop, plugged in the usb AOC monitor and the monitor is working. My issue is resolved.
