Problem with nvdia-driver on kali linux

Hello, i have very slow work kali linux. I have nvidia geforce 940mx and intel core i5.
I installed linux headers and run : apt install nvidia-driver
after that, my kali linux worked very fast!
But when i reboot my system, linux again is very slow.

I tried run : nvidia-settings and get the error:

ERROR: Unable to load info from any available system.

command results:

lspci | grep VGA
