I have notebook Xiaomi Mi Pro 15.6. The notebook has GeForce MX150 graphic adapter. I enable Nvidia driver in additional drives,
but when I go to Settings -> Details -> About I see: Graphics: Intel® UHD Graphics 620 (Kabylake GT2)
How enable GeForce MX150 ?
Given than you installed the drivers using the additional drivers tab, you should have already installed Nvidia Settings. Look in there for the PRIME Profiles menu and use it to switch between the two cards as shown in the image:
Alternatively, you can open your terminal and write the command
prime-select query
to check which of the cards is your system using, and the commands
sudo prime-select nvidia
or
sudo prime-select intel
to change between the two cards and then restart the session.
When it is about Nvidia, it is better to install the proprietary driver.
Here is a detailed answer:
To remove the installed Nvidia drivers, run:
sudo apt-get purge nvidia*
sudo apt remove nvidia-*
sudo apt autoremove
Then, check which is the recommended driver for your Nvidia card by running:
ubuntu-drivers devices
If you want to install the driver automatically, run :
sudo ubuntu-drivers autoinstall
If you want to install a specific driver, run:
sudo apt install nvidia-<driver number>
Once the installation is finished, run prime-select query to check which graphic card is being used by your device.
If you want to change the graphic card used by your PC, run : sudo prime-select <intel/ nvidia>; choose between Nvidia and Intel graphic cards.
After that, restart your PC to apply changes
Here is explained the right answer, i hope it helps you.

I had the same issue on a HP Spectre x360 and I solved it by disabling secure boot in the BIOS.
