The system is running low graphics mode after nvidia driver installed on Ubuntu 16.04

Hello team,

I have a server with 8 card GeForce RTX 2080 Ti
I want to install Cuda 9.0.

First, I disabled the Nouveau drivers, then I installed the latest Nvidia driver for x86_64 architecture (Linux_x86-64_440.44) by running the following commands:

  1. sudo service lightdm stop
  2. sudo sh. NVIDIA-Linux-x86_64-440.44.run

It was successful, but When I reboot the system, there is an error message:

“The system is running low graphics mode”

I tried installing some other driver but the results were similar.
Please help me ASAP
Thank you!

Your Xorg server is crashing - I’ve no idea why. Please update your system to latest version of all components and update your BIOS as well (if an update is available).

I’ve noticed that you have this “VGA compatible controller [0300]: ASPEED Technology, Inc. ASPEED Graphics Family [1a03:2000] (rev 30)” - can you try disabling it in BIOS?

The server is crashing because there are too many autoconfigured GPU devices and it’s overrunning an array that has a hard-coded limit of 20:

45.917] (==) Matched ast as autoconfigured driver 0
[    45.917] (==) Matched nvidia as autoconfigured driver 1
[    45.917] (==) Matched nvidia as autoconfigured driver 2

This bug is fixed in xserver 1.20: https://cgit.freedesktop.org/xorg/xserver/commit/?id=5d3b6cc221aff5b9322b31aa6f5ae922271bc7d8

You might be able to squeeze in under the limit by removing the nouveau driver, but upgrading to a fixed X server would be your best bet.
