Which Nvidia driver do you have installed? On Ubuntu 24.10, I had to install install nvidia-driver-550-server to restore support for my older 1060 card.
NVidia says you need a 390-series driver for the K2000M. You could try adding this PPA: Proprietary GPU Drivers : “Graphics Drivers” team, and install the older driver. It should give you the required pieces, see here:
