How to disable USB 2.0 driver
Currently, I am using 2 display link monitors. They both work great for the most part. However, if I leave my USB 2.0 displaylink monitor plugged in while I boot up my computer, the resolution options only go up to 1024x800 instead of 1920x1080.

I believe that the cause of this is that there is a displaylink USB 2.0 driver in the kernel. I found that here: https://plugable.com/category/platform/linux/ . I realize that those posts are old, but I still believe that there's something in the kernel for displaylink 2.0 devices. The device that I'm having trouble with is this: https://plugable.com/products/uga-165/. I believe that this also says some of the problems I'm having: https://support.userful.com/UMs/Manu...eo_Connections . I understand that this isn't the fault of displaylink, but any help would be appreciated.

Is there a way to disable the driver/module that's causing me issues? The resolution options are also limited if I unplug and plug back in the adapter

I'm running Kubuntu 18.04 and have the latest displaylink drivers installed.

I figured out that it was the "udl" module that wanted to do its own thing with USB 2.0 devices. To disable it, I followed this tutorial: https://linuxconfig.org/how-to-black...u-debian-linux and blacklisted udl.
