The 5.1 kernel is not yet supported by the most recent DisplayLink driver release, but it is already supported in the devel branch of evdi (https://github.com/DisplayLink/evdi) which we will be using in future Linux driver release.

You can compile evdi from github manually and use it with the 5.1 DisplayLink driver, although you would need to extract installer components and modify the installer script to cope with it (i.e. so it doesn't attempt to build the bundled evdi tarball).

Cheers,

Hey there. Though it's been long since you posted here, I'd like to know if you've fixed that problem. I've faced a similar issue, so I'd like to know if you can help me.

Take a look at this link.

I've tested it and unpack the official ubuntu package and creates installable rpm packages that works great on fedora, Unfortunately they don´t work with my mandriva fork since it creates packages with Fedora SystemD scriplets not compatible with my distro.
