Nvidia installation on Lenovo Ideapad l340


I have Lenovo l340 laptop with video card GTX 1650, Debian 10 installed and I’m trying to install the Nvidia driver from the official site. Every time when I finish the installation the laptop stuck on boot and cannot start. I tried with several driver versions 4.18.xx and above but is the same.

More information about my system is available below:

uname -a
Linux myuser 4.19.0-6-amd64 #1 SMP Debian 4.19.67-2+deb10u1 (2019-09-20) x86_64 GNU/Linux

lspci | grep ‘VGA|Nvidia’
00:02.0 VGA compatible controller: Intel Corporation UHD Graphics 630 (Mobile)
01:00.0 VGA compatible controller: NVIDIA Corporation Device 1f91 (rev a1)

Currently I have the driver somehow running by removing xorg.conf file but is not working properly.

When I try to open nvidia-settings from terminal I see error:

Invalid MIT-MAGIC-COOKIE-1 keyUnable to init server: Could not connect: Connection refused

ERROR: The control display is undefined; please run nvidia-settings --help for usage information.

I appriciate any help.
