Hi!
I bought without researching a (cheap) Lenovo USB 3.0 Dock hoping to connect one extra monitor to my laptop. It turns out that video through USB is not part of the standards and thus proprietary. There is luckily a package available here: https://github.com/displaylink-rpm/displaylink-rpm
Still it doesn't work. I'm getting this:
systemctl status displaylink.service displaylink.service - DisplayLink Manager Service Loaded: loaded (/usr/lib/systemd/system/displaylink.service; static) Active: activating (auto-restart) (Result: exit-code) since Fri 2021-04-02> Process: 3954 ExecStartPre=/sbin/modprobe evdi (code=exited, status=1/FAILU> CPU: 4m
and this: sbin/modprobe evdi modprobe: FATAL: Module evdi not found in directory /lib/modules/5.11.10-200.fc33.x86_64
Has anyone any experience on the topic or should I just ask on their github project?
It sounds like you haven't actually got a compiled version of the kernel module evdi, so something is broken there. Perhaps you built it against a kernel you aren't booted into?
I looked and the RPM Sphere 3rd-party repo has a dkms package for evdi:
I don't know if the repo is trusted, but there is a source RPM here: https://github.com/rpmsphere/source/blob/master/e/evdi-1.8.0-1.src.rpm
