The recommended Nvidia driver for my card (1050ti) is 435.12. However, I cannot get any proprietary drivers to show up in the Additional Drivers list, nor can I install the Nvidia binary package directly.
So far, this is a clean Ubuntu 19.04 install, with the exception that I've disabled Wayland (made no difference).
Update: I manually added ppa:graphics-drivers/ppa
but still it did not show me the correct proprietary driver packages.
