As of May 29th 2017, if you want to do something crazy like use *both* ports of the OneLink+ dock to use monitors that aren’t 640×480 (but aren’t 4k), you’re going to need a 4.11 kernel, as everything else (for example 4.10.17, which is the latest in Fedora 25 at time of writing) will end you in a world of horrible, horrible pain.

To install, run this:

sudo dnf install \
https://kojipkgs.fedoraproject.org//packages/kernel/4.11.3/200.fc25/x86_64/kernel-4.11.3-200.fc25.x86_64.rpm \

https://kojipkgs.fedoraproject.org//packages/kernel/4.11.3/200.fc25/x86_64/kernel-tools-libs-4.11.3-200.fc25.x86_64.rpm \

This grabs a kernel that’s sitting in testing and isn’t yet in the main repositories. However, I can now see things on monitors, rather than 0 to 1 monitor (most often 0). You can also dock/undock and everything doesn’t crash in a pile of fail.

I remember a time when you could fairly reliably buy Intel hardware and have it “just work” with the latest distros. It’s unfortunate that this is no longer the case, and it’s more of a case of “wait six months and you’ll still have problems”.

Urgh.

(at least Wayland and X were bug for bug compatible?)
