Logout from your currenet session or restart pc to make this change effctive.

Btw , that Ubuntu system info screen always shows Intel on there. Ignore it.

When you run inxi -SMGxx command , output should be like that.

First things first: Don’t use Wayland , use X.

Second: You’re still on Intel as we can see at renderer line.

Third: Open terminal and do this:

sudo prime-select nvidia

See if this will work or not.

5

already did.

Info: the nvidia profile is already set

Please make sure you disabled wayland:
[url]xorg - How to disable wayland in 17.10 in gdm3 login screen - Ask Ubuntu
If that doesn’t help, check if the file /lib/modprobe.d/nvidia-kms.conf exists and change
modeset=1 to modeset=0
and run sudo update-initramfs -u

7

I disabled it and now the boot loading stop on the Ubuntu loading before the logging

8

Any solution?

9

Check if using lightdm instead of gdm helps:

I followed the installation and selected gdm3, but nothing seems changes

11

I’m not sure what exactly you did now, you should have done

12

sorry for the attendance. I attached the file in the original post

13

I also got that problem. Anyone help me.

A simple resintall of nvidia drivers fixed my issue
sudo apt-get install --reinstall nvidia-driver-440
