The 3 basic steps required are described in some detail in the post
"Installing Lubuntu 18.04.4 on a troublesome old PC",
https://ubuntuforums.org,showthread.php?t=2440098
The 1st step, downgrading Xorg, is different for Ubuntu 20.04 flavours
than for Ubuntu 18.04 flavours.
It is implemented as follows:
-collect the following bionic video modules in a directory
xserver-xorg-core_1.19.6-1ubuntu4.9_amd64.deb
xserver-xorg-legacy_1.19.6-1ubuntu4.9_amd64.deb
xserver-xorg-video-amdgpu_18.0.1-1_amd64.deb
xserver-xorg-video-ati_18.0.1-1_amd64.deb
xserver-xorg-video-fbdev_0.4.4-1build6_amd64.deb
xserver-xorg-video-intel_2.99.917+git20171229-1_amd64.deb
xserver-xorg-video-nouveau_1.0.15-2_amd64.deb
xserver-xorg-video-qxl_0.1.5-2build1_amd64.deb
xserver-xorg-video-radeon_18.0.1-1_amd64.deb
xserver-xorg-video-vesa_2.3.4-1build3_amd64.deb
xserver-xorg-video-vmware_13.2.1-1build1_amd64.deb
-replace the focal graphics from this directory with the
command, sudo dpkg --install xserver*.deb
************************************************** **********************
For the 2nd step, downgrading the Linux kernel, I tested with
the 4.14.175 kernel from
https://kernel.ubuntu.com/~kernel-ppa/mainline/v.4.14.175
There are newer 4.14 kernels than this one, but they are all
designated as being in a test state. V4.14.175 is the latest
one designated as stable.

The 3rd step, installing the proprietary NVIDIA drivers, is the same,
as described in enigma9o7's thread, "nvidia won't install",
