X Server does not start with 9x Tesla P100 + 1x Quadro - Ubuntu 16.04 & 18.04 driver 375, 390, 396

Hi,

we have problems to get a Tyan 10 GPU server running with Ubuntu 16.04 or 18.04.

Ubuntu starts correctly to gui login screen with 8x Tesla P100 + one quadro graphics card (P400, K4000, P1000…)
nvidia-smi shows all gpu devices, everything is fine.

But when starting with 9x or 10x Tesla P100 + Quadro the system only starts to tty terminal. Manually starting x server with startx breaks with “Segmentation fault at address 0x0”

We can exclude thats a faulty Tesla card, PCIe Slot or quadro card.

Also the system is running correct with 10x Tesla + 1x Quadro in Windows 10. All GPUs running and get correct CUDA benchmark.

We have tried following driver combinations:

Ubuntu 16.04
Installation with 375.xx deb file
apt-get install nvidia-390
apt-get install nvidia-396

Ubuntu 18.04
apt-get install nvidia-390

When deinstall the nvidia driver and reboot, the system start correct with gui login.
When remove Tesla cards to only 8x + Quadro, the system works fine.

Here is the logfile of X Server failed with 10+1 GPUs:

nvidia-bug-report.log (1.69 MB)

Telling by the backtrace, the Xserver is crashing while trying to log something. Should be reported to the xorg bugzilla.
Meanwhile, you could try to just enable the Quadro for the xserver:
/etc/X11/xorg.conf

Section "Device"
    Identifier     "nvidia"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BusID          "PCI:24:0:0"
    Option         "AllowEmptyInitialConfiguration"
EndSection

Section "ServerFlags"
    Option "AutoAddDevices" "false"
EndSection

and maybe remove the file /usr/share/X11/xorg.conf.d/10-nvidia.conf

This looks a lot like the crash that was fixed in this X server change: https://gitlab.freedesktop.org/xorg/xserver/commit/5d3b6cc221aff5b9322b31aa6f5ae922271bc7d8
I don’t recall whether disabling AutoAddDevices helps with that one. It can’t hurt to try it.

I don’t think that fix ever got backported to the 1.19 server branch. Would trying xserver 1.20 be possible? Alternatively, you can try removing the OutputClass file from /usr/share/X11/xorg.conf.d to avoid overflowing the autoconfig driver array.

Hi generix,

thanks for your Reply. Modifying the xorg.conf resolved the Problem.

Creating the xorg.conf with only section “device” for the quadro card helps to resolve the display problem.
But with this config i had no keyboard and mouse support (very frustrating because i thougt the system were freezed. It took some time to realize that the system is already running and only input devices did not work :-) )

The final solution were to use the tool nvidia-xconfig to generate a basic xorg.conf file (with input devices :-) ) and then make the modifications from your suggestion. The AutoAddDevices “false” Option seems not to work.

I had also an idea whats went wrong with automatic driver installation. I’ve made an octane benchmark to ensure that all cards working correct. One of the Tesla were recognized by Octane as Device 0, so i think without generix xorg.conf modification xserver tries to start gui on Tesla card instead of quadro.

Attached you’ll find the Octane screenshot. And also the log of running Xorg.

Probably helpful for someone here are the final xorg.conf file:
