Search with Google for "NVidia 525 driver not installing Ubuntu" for the sorry tale of NVidia 525 vs. Ubuntu and Mint. There's a dependency problem and the install fails. There is much discussion of workarounds. If you try this using the "additional drivers" GUI program, you get a dialog box with a big X and an "OK" button, but no message.
If you want to run Wayland on NVidia hardware, you need to be heavily into Linux system administration.
Filed two bug reports. Back to Xorg.
