Public bug reported:
First, I added this PPA via the usual procedure:
$ sudo add-apt-repository ppa:graphics-drivers/ppa
Below there is the NVidia chipset I want to install the drivers for:
$ lspci | grep -i --color 'vga\|3d\|2d'
00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated
Graphics Controller (rev 0b)
04:00.0 3D controller: NVIDIA Corporation GF117M [GeForce 610M/710M/810M/820M /
GT 620M/625M/630M/720M] (rev a1)
However, even after installing the PPA, apt still prefers to install the
version from the Ubuntu repos, see log below. After some discussion on
the #kubuntu IRC channel, I have been advised this is not the expected
behaviour and I have been encouraged to file an issue here. An option
was the Ubuntu repos listed this chipset incorrectly, but I don't have
enough expertise on this field to confirm that.
$ apt-cache policy nvidia-driver-440
nvidia-driver-440:

Forcing the PPA version leads to broken packages, as shown below:
$ sudo apt install nvidia-driver-440=440.82-0ubuntu0~0.20.04.1

-----------------------
I never could get NVidia drivers to work on this computer when using 18.04 LTS.
In fact, I switched to a fresh install of 20.04 LTS yesterday, where the
'Install third-party drivers' checkbox installed nvidia-driver-340. However,
even on a fresh install only a black screen appeared (terminal could still be
accessed via ctrl+alt+f2), as it also happened on 18.04 LTS. So the only way to
get the system to work is not to install any third-party drivers (I did another
fresh install) and use the integrated graphics chipset instead. This is fine
most of the time, except from video games, of course.
