What I have:

GA-B250-Fintech motherboard

Ubuntu 18.04 (but I'm ready to reinstall to any version if it will work)

$ uname -r

And P104-100 video card.

$ lspci | grep NVIDIA
01:00.0 3D controller: NVIDIA Corporation GP104 [P104-100] (rev a1)

gcc --version
gcc (Ubuntu 7.4.0-9ubuntu1~18.04.york0) 7.4.0

I tried to install different nvidia drivers: 390, 410, 418, 430. Still doesn't works. I suppose it's about motherboard/BIOS setup or xconf file.

The problem: every time I install nvidia drivers, Ubuntu stop loading. Usually with message:

started user manager uid 121.

I plug out P104-100 and plug in GTX 1060, this works correctly:

~$ nvidia-smi

|  No running processes found                                                 |

Then I tried plug in P104-100 as second card using another slot, and Ubuntu stops loading: freeze with message

Started GNOME Display Manager.

Sometime it can be

Started Disk Driver

or smth else (so looks like it is not the real error message).

P.S. Using lshw -C display I found both cards have physical id: 0 Can it be a reason?

Question: How to install both cards on Ubuntu? I think if I successfully install P104-100 as single card the same solution could be for installing both of them.

P.S. I found some solution about editing xconf for using on multiple GPUs: for example. But it did not help.

I also had problem to connect second monitor - solved it by changing BIOS parameters. So I tried the same for P104 - turn on/off all the parameters in BIOS but every time Ubuntu freezes.

    @BudgetTech Hi! Yes, I have tried 19.04 because it has preinstalled driver (418 as I remember). So it's loading to ubuntu without errors, but still doesn't see P104 GPU: nvidia-smi find only 1060. – Mikhail_Sam May 17 at 8:26
