Linux Distribution: Ubuntu 20.04 LTS ("Focal Fossa")
Desktop Environment: GNOME 3.36.3
Graphics Card: Nvidia GeForce MX250
GPU Driver Version: 440.100 (according to Nvidia X Server Settings)
Have you checked for system updates?: Yes
If this is not Steam, you can still give us a system readout using inxi with "inxi -SbCGxx" in terminal (please put that into Pastebin/Gist as linked above!): https://pastebin.com/3aMPkneF
You can note your issue below here
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".
I tried to remove all of the Nvidia drivers using:
sudo apt purge 'nvidia.*'But I am told:
E: Unable to locate package nvidia.*Here's the output of `lspci -k | grep -EA3 'VGA|3D|Display'`:
00:02.0 VGA compatible controller: Intel Corporation UHD Graphics (rev 02)DeviceName: VGA
Subsystem: ASUSTeK Computer Inc. UHD Graphics
Kernel driver in use: i915
Kernel modules: i915
--
02:00.0 3D controller: NVIDIA Corporation GP108BM [GeForce MX250] (rev a1)
DeviceName: Second VGA
Subsystem: ASUSTeK Computer Inc. GP108BM [GeForce MX250]
Kernel driver in use: nvidia
Kernel modules: nvidiafb, nouveau, nvidia_drm, nvidia
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?
Note any particular steps to reproduce it below here
Open the "Additional Drivers" tab using "Software & Updates" with the same or similar hardware.
apt-get expands the * into a list of matching packages, but I don't think apt does. I can't remember if aptitude does.
The latest stable driver is 450.66. I use the PPA and I'm still on 18.04, so I couldn't tell you whether the 450 branch has been added to the Stable Release Updates for Focal yet. 440.100 is the latest version on the 440 branch. You could either add the PPA or just wait.

Yeah, your suggestion work worked...
sudo apt-get purge nvidia*Restart.
sudo apt-get updatesudo apt-get autoremoveRestart.
Re-installed the proprietary driver via "Software & Updates".
Restart.
Went back into "Software & Updates" - now it says I am using the latest proprietary driver ("450", at the time of writing).
Thanks for your help!
