(superseeded) Linuxcnc on Linux Mint 19.3 quick and easy installation

Tom, Thanks a ton
Up and running now. I have to say the praising of mint has something to it. Mate is not too far away from KDE at all. have to figure out how to switch to my kbd layot yet, but that is a question of patience and brain juice. I'll manage that.

Edit: kbd layout was just a piece of cake, start to really like mint

Nice.
I like Mate as it is the closest thing to Gnome2 .
Gnome3 was and is a ............. insert bad words here!

I like to use an rt kernel 4.19.0-9-rt-amd64 with mint, as I get realtime delays with kernel 5.4.0-0.bpo.4-rt-amd64. How can I do that?

It is safe to ignore those warnings.

I am a bit puzzled: i915 seems to be still alive?!

That is not a big issue at all, the overall latency is still good with 5.4 if you want to use software stepping.
If you do not need software stepping ( parallel port) you can ignore the base thread latency issues and use only the servo latency numbers.I'll try to find that kernel a bit later.

Yup, it seems so, despite all the warnings. Did not notice that, thank you.
