I have a fairly fresh install of Fedora 34 that I use with a USB dock. The dock has been working great for data, power, audio, and usb for a month. I just added two monitors to the setup connected by DisplayPort and my laptop can't detect them. HP Spectre x360 15 w/ GeForce GTX 1650 Ti \ Lenovo ThinkPad USB-C Dock - 40A90090US \ Two Planar PZN2410

DisplayLink drivers have been installed from https://github.com/displaylink-rpm/displaylink-rpm . I'm new to linux. Every solution I've found online involved updating to drivers, modes, or kernels that I seem to already be using. Any advice on a how to get the monitors detected would be greatly appreciated.
