I am running ubuntu 20.04 on lenovo yoga slim7 laptop which is loaded with nvidia 350M graphics card.
I add ppa and apt installed nvidia-470 driver which is the latest one however GPU does not seem to be utilized for desktop GUI rendering as I feel delays in any screen input even for terminal.

Here is what the settings > About page look like.

I checked lspci to find VGA controller but could not find nvidia here.

$ lspci | grep VGA  

00:02.0 VGA compatible controller: Intel Corporation Iris Plus Graphics G1 (Ice Lake) (rev 07)

and only find

$ lspci | egrep -i "vga|display|3d"  

00:02.0 VGA compatible controller: Intel Corporation Iris Plus Graphics G1 (Ice Lake) (rev 07)  

30:00.0 3D controller: NVIDIA Corporation GP107M [GeForce MX350] (rev a1)

Additional info

$ lspci -k | grep -EA3 'VGA|3D|Display'
