--00000000000012e53a05c64603ca Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable Which version of nvidia-driver? If it=E2=80=99s stuck on 390 you will need = to manually create two XScreens and target the two gpus accordingly with =E2=80=9Cpciconf -lv=E2=80=9D b/s/f numbers in this stanza. I think newer = cards&drivers might handle this better with glvnd but would like to hear a user report of two non-SLI nvidia cards with >460 drivers and recent ports tree like 2021Q3. https://forums.developer.nvidia.com/t/multi-nvidia-gpus-and-xorg-conf-how-t= o-account-for-pci-bus-busid-change/34556 If it works on Linux guides it should only need minor modifications for FreeBSD.
