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

Can you please set pncconfig without tuning, save it and see if ti works.
All the tuning you can do at any time later.

Start a new topic, and give us more details.

Added a much easier way of installing it to the original post, it now uses RT 5.4 kernel from Debian repos.
Also included is the script to automate everything.

What's the latency like with the 5.4 Kernel ?

Do the headers install ok ? I've seen issues when installing headers from Debian on Ubuntu systems due to mismatching of gcc and various other utilities.

Installed it on a Lenovo T420S, it is a lot better than 4.09 or 4.19 , latency histogram never goes above 105K, but it will drop the connection to Mesa 7i92 after roughly 10 minutes. That is something else i noticed last night with it, when running latency-histogram the processors are locked at 3.3GHz all the time and they do not go down even when switching from power to batteries and vice versa, while when running Linuxcnc it never goes above 2.8GHZ and it drops very often to 2.6GHZ, so that might be the reason for the spikes and the drop of connection.
On an Asrock H61M MB with a dual core celeron, it is the same as far as i can tell.
I did not install the headers at all, could not find them so i gave it a try without it and it all works properly so far, to early to decide, but not noticing anything missing or non functional.
The 5.4 will complain about missing driver for an Realtek net card and for I915 chipset, not using any of those so it is good for now.
