Nvidia graphics card not detected on Ubuntu 17

[ask]

I am running Civilization 6 game via Steam launcher.

this is on Ubuntu 17.10:

when I boot Windows 7 on the same computer and start Civ6 (via Steam launcher in both cases), it shows proper video card in "GPU selection" field.

Ubuntu settings:

$ lshw -c video
