NVidia GTX1660 Ti Max-Q (driver 440.44) on Ubuntu 19.10: unable to select graphic card (using integrated one)

Graphics / Linux Linux
#1

Hello!

I installed the lastest Nvidia driver using PPA. The driver looks perfectly installed. The problem is the system is not using it. It is using the AMD integrated graphics card (AMD® Ryzen 7 3750h with radeon vega mobile).

$ inxi -Gx

It looks to be selected but the system does not use it:
$ sudo prime-select query

[/i]

I can not access to nvidia-settings:
[i]$ sudo nvidia-settings

ERROR: Unable to load info from any available system

** Message: 01:55:15.804: PRIME: No offloading required. Abort
** Message: 01:55:15.804: PRIME: is it supported? no
[/i]

Any advice? Thank you very much on advance!
PS: creating the topic I have seen an option to attach the nvidia-bug-report, maybe you need more information

Thank you very much!
This solves the problem. My system is using Nvidia Card now! And I can configure it using “nvidia-settings”.
