Upon opening Civilization VI, it does not detect my graphics card, an Nvidia 820M, instead using my Intel graphics. (It also has a strange graphical glitch which renders much of the game as blue patches.) It did not find the card when I just had nouveau installed, nor did it find it when I installed nvidia-340 or nvidia-375. (I already have Secure Boot disabled.) I have tried installing various such drivers, none of which have helped. I presume that the graphics card is not being used by the rest of the computer, but am not sure. How can I resolve this?

lspci -k | grep -EA3 'VGA|3D|Display' returns

    Please edit your question and add output of lspci -k | grep -EA3 'VGA|3D|Display' terminal command and also prime-select query. – Pilot6 May 27 '17 at 19:57
  • @Pilot6 I have done so. – Benedict Randall Shaw May 28 '17 at 13:16
  • The Nvidia driver is not used. Most likely Secure Boot is enabled. How did you install drivers? – Pilot6 May 28 '17 at 14:09
  • I installed nvidia-375 using apt-get, as it didn't show on Additional Drivers. (I had the same errors using nvidia-340, which is on Additional Drivers.) I disabled Secure Boot when installing nvidia-375. – Benedict Randall Shaw May 28 '17 at 17:29
