Hi,
I use Linux Mint for many years and Pascal Lazarus for about one year.
I've just installed it for a friend on a old laptop 2 cores a few days ago.
I'm on Linux Mint 20.2 Cinnamon 64Bits, Kernel 5.15.0-78-generic
newer versions have sometimes problems with old computers and NVidia Graphics cards.
Don't use the Lazarus version on Mint repository, it is not the latest.
Uninstall it with the "Software manager"
or
Uninstall it completely with "Synaptic Package Manager"
Search for "fpc", look what is installed (Green square), select it with Right Click and "Mark for Removal" then "Apply"
Do the same with "lazarus"
For the installation, I download the 3 packages from here:
https://sourceforge.net/projects/lazarus/files/Lazarus%20Linux%20amd64%20DEB/Lazarus%202.2.6/
I install the 3 packages in order:
fpc-laz_3.2.2-210709_amd64.deb
fpc-src_3.2.2-210709_amd64.deb
lazarus-project_2.2.6-0_amd64.deb
By clicking on the .deb file you run the "Archive Manager" then "Install"
After the first run, I install "anchordockingdsgn" from "Package->Install/Uninstall Packages" to have a pleasant environment.
For Graphic, I use "BGRABitmap" and "BGRAControls" from "Package->Online Package Manager"
Hope that help.

Thank you for your description and links.
lazarus, fpc, fpc src and fp (fp unit) was needed to uninstall all the things.
Now I'm not sure if to uninstall the libfprint, probably something different, so not.
Now installing
sudo gdebi -n -q fpc-laz_3.2.2-210709_amd64.deb fpc-src_3.2.2-210709_amd64.deb lazarus-project_2.2.6-0_amd64.deb
It seems that it is installed but I cannot run it:
sudo gdebi -n -q fpc-laz_3.2.2-210709_amd64.deb fpc-src_3.2.2-210709_amd64.deb lazarus-project_2.2.6-0_amd64.deb
