When I open Software & Updates, I am told that I am using a "manually installed driver" (which is apparently not proprietary):
I'm not too sure why Ubuntu is telling me this, as I explicitly chose to use the latest version of Nvidia's proprietary driver when I "clean" installed Ubuntu on Launch Day... I installed this driver via the "Additional Drivers" tab of "Software & Updates".
Somebody asked a similar question over here, but when I followed the suggestion over there, I am told:
E: Unable to locate package nvidia.*
Here's the output of lspci -k | grep -EA3 'VGA|3D|Display'

How can I select Nvidia's proprietary driver in the "Additional Drivers" dialog box, to ensure that I am using the current (stable) version of their proprietary driver?
My laptop is the ASUS ZenBook Duo UX481FL, with an Nvidia GeForce MX250 GPU under Ubuntu 20.04 LTS ("Focal Fossa").
Got it fixed... The way I did it was like this:
Restart my laptop.
Restart my laptop.
Re-install the proprietary driver via the "Additional Drivers" tab of "Software & Updates".
Restart my laptop.
I Went back into the "Additional Drivers" tab of "Software & Updates" - now it says I am using the latest proprietary driver ("450", at the time of writing).
