Instalei recentemente o Ubuntu 18.04 e instalei o driver NVIDIA, mas eles não parecem estar carregando.
Eu tive que fazer a seguinte edição no meu arquivo grub para fazer as coisas inicializar corretamente como por este pequeno guia .
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nouveau.modeset=0 tpm_tis.interrupts=0 acpi_osi=Linux i915.preliminary_hw_support=1 idle=nomwait"
Isso é o que minhas saídas de comando atualmente fornecem:
$ nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

Eu instalei os drivers via sudo ubuntu-drivers autoinstall como por este guia
EDIT: Aqui estão mais algumas saídas de comando:
$ dpkg --get-selections | grep nvidia-driver-
nvidia-driver-390 install
$ lsmod | grep nvidia
<blank>
$ ls /lib/modules/*/updates/dkms/nvidia.ko
/lib/modules/4.15.0-38-generic/updates/dkms/nvidia.ko
Recentemente, tive o mesmo problema. Para que funcionasse, o que fiz foi:
sudo apt purge nvidia* ) sudo prime-select nvidia sudo prime-select intel sudo prime-select nvidia Espero que isso ajude alguém.
