]SOLVED SOLUTION [ Issues With DisplayManager and NVIDIA

user79946 · December 4, 2021, 9:11am

OS no longer start DisplayManager while attempting to install Nvidia drivers.

This is what I did. I installed Nvidia drivers for my :
01:00.0 VGA compatible controller: NVIDIA Corporation GF108GLM [Quadro 1000M] (rev a1)
using : NVIDIA-Linux-x86_64-390.144.run

Now my DissplayManager fails to start and I am not sure how to resolve.

Had to use pastebin since there are links in the output.

I have to 2 video outputs a VGA and Displayport.

lspci | grep VGA

00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
01:00.0 VGA compatible controller: NVIDIA Corporation GF108GLM [Quadro 1000M] (rev a1)

The following file is needed /etc/X11/xorg.conf I made one for each setup. It is important to modify : Section “Device” and set the hardware ID for the NVIDIA Displayport : BusID “PCI:1:0:0” .
The driver is necessary to specify : Driver “nvidia”

This xorg.conf will disable the laptop screen and display only video from the Displayport.
