Installing LinuxCNC 2.9 or Master on Linux Mint 21

Been to long, but i do recal one of those does floating point calculations while the other does not. No idea as to why or how, i forgot.
One remark, if you plan on using the parallel port, test for base period as that limits the amount of steps per second produced, coupled with step timings.
Last 3 years i have moved to Mesa ethernet boards for everything, so no need for base period and latency is not an issue anymore as most new-ish PC's are OK, although some are useless, had one of those.
Still, the amount of tweaks you and NTULINUX figured out is astonishing, thank you all.

Why i am on parport ?

I did not ask, i absolutely love parallel port since the days of bad floppies and parallel being very good at transferring data very fast for the time. FX.exe ??? Anyone?

That is why they never work, cost extortionate amounts of money, and orders getting canceled daily! The culmination of "get some engineers from (enter 3'rd world country) to build the most complicated (insert equipment/project/software of choice)" then present that to public as "the best thing since sliced bread" and subsequently failing monumentally, while people end up with the bill showed so deep down their throat ....
F35 would have been much better if they used 11 parallel ports, it would work and work reliably!

I did try on Mint 19 and it worked, i did not try on Mint 21 so i do not know if it works.
