Nvidia Driver won't install on Ubuntu 20.04

drivers nvidia graphics 20.04

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.

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

  Did you reboot your PC after installing the drivers? If not, reboot then run prime-select query to check which GPU your PC is using.

  May removing the installed Nvidia driver and reinstall it again using sudo ubuntu-drivers autoinstall would work.. This might be helpful

  What does sudo update-alternatives --config glx tell you? Is Nvidia set as default?

  update-alternatives: error: no alternatives for glx

  if @karel solved your problem, you should mark that as the answer. in my case this has nothing to do with secure boot.
