Comment 4 for bug 1772787

Hello Team,

I'm experiencing similiar issue on Ubuntu 16.04 on Dell 5820 Tower. I'm using Display port monitor, inorder to get proper display I need to download nvidia driver from ppa:graphics-drivers/ppa

After install nvidia-384 and did a reboot, still no display, but can able to see the PCI modules conflicted

#lspci -v
lspci: Cannot open /sys/bus/pci/devices/0000:00:03.0/resource: No such file or directory

There is no issue with Ubuntu 18.04 , which is works perfectly on the same machine. Ubuntu 16.04 having issue.

Below is the environment details.
