Which kernel modules wouldn't come as precompiled packages in Ubuntu ? (real question - as an Arch user for instance I haven't had the need for DKMS for years)
DisplayLink is something that comes to mind. For Arch (btw i use) it needs DKMS and comes out of the AUR[0]. For Ubuntu, it looks like you need some 3rd-party packages that will need to be compiled for modern kernels.
