Installed driver with this command:
$ sudo apt install nvidia-driver-440
but when i want to check Nvidia driver, I'm getting this error:
$ 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
If I look at Nvidia-settings, the window will show up, but all i can see is: Select GPU you would like to use and 3 options below, and nothing else. Here's the output:
$ nvidia-settings
ERROR: NVIDIA driver is not loaded
ERROR: Unable to load info from any available system

in Software & Updates > Additional Drivers, I chose: Using NVIDIA driver metapackage from nvidia-driver-440 (proprietary, tested)
In Settings > About, Graphics: displays integrated Intel, instead of Nvidia 1050TI
Did everything as in
This comment, :
$ prime-select query
nvidia
It says nvidia, but still nothing's working
FIXED:
I managed to fix it by disabling secure boot in BIOS
Best Answer
You have the correct Nvidia 440 proprietary graphics packages from the default Ubuntu 20.04 repositories installed, but the integrated Intel graphics processor is being used instead of Nvidia graphics. Disable Secure Boot in BIOS/UEFI.
