Hi,
What version of Mint do you use?
64 or 32 bits?
I use Lazarus on multiple linux Mint P.C. and even netbook without problem (some are old: only 2 cores)
Don't use the Lazarus version on Mint repository, it is and old version.
if you already installed Lazarus from Mint repository
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 // The compiler for 64 bits
fpc-src_3.2.2-210709_amd64.deb // The sources for 64 bits
lazarus-project_2.2.6-0_amd64.deb // The IDE for 64 bits
By clicking on the .deb file you run the "Archive Manager" then "Install"
or in console:
sudo dpkg -i <package.deb>
After the first run, I install "anchordockingdsgn" from "Package->Install/Uninstall Packages" to have a pleasant environment.
And rebuild Lazarus IDE
