I have recently changed my Nvidia GPU, and I am having problems to boot Ubuntu. I get a blank screen after GRUB.

When I boot in recovery mode (it works) and type the command nvidia-detector, I get:

nvidia-driver-440

And when I type nvidia-smi, I get:

+-----------------------------------------------------------------------------+
| NVIDIA-SMI 430.50       Driver Version: 430.50       CUDA Version: 10.1     |

I followed [1], [2], and [3] to completely uninstall the drivers and then install it again.

My question is: Does anyone know why Ubuntu is showing two different driver versions, and how can I solve it?

  • @Vimeiro did you manage to fix this issue? I'm having a similar problem with 435 installed but nvidia-detector detecting 440. – Liam Baker May 15 at 7:27
  • @LiamBaker, I completely removed everything related to Nvidia, and installed the Nvidia driver again from PPA repository [1]. I followed the tutorials I mentioned above and also these ones [2], [3], [4]. They are related to ML but have drivers installation steps as well. – Vimieiro May 15 at 11:26
