Yes it is and i am glad it worked out for you....no it works, there is a new kernel (5.4.0-0.bpo.4-rt) now isnt it? With the new kernel it works....

But you can do at any timeThat will update everything including LinuxCNC, but not the kernel.

It should.If I put them back in my home directory will the new install pick up the old settings?
No, not the kernel, if it is working for you, stick to it.Also should I do updates in the LinuxCNC kernel?
But you can do at any time
sudo apt update
sudo apt dist-upgrade

Hey Tommy, I tried this on my Gigabyte BRIX S with the 4.9 kernel. uname -a shows the kernel is up. I can't get Linuxcnc to run outside of simulation though, it worked on 19.3. Any ideas?

A little more verbosity would help ?
What errors are you getting ?
The same packages from Ubuntu bionic are a better match for Mint 20.0 along the Linuxcnc packages from my repo. There is also a couple of kernels there as well.
The uspace-dev package will install fine if you need to build any user comps.
Before jumping onto 5.4 kernels this might be interesting

I'm not getting any errors, per se. I'm getting Linuxcnc only running in simulation mode. I had 19.3 on the machine but with the 5.4 kernel, and my servo thread was way too high even for a Mesa ethernet board. I couldn't get 19.3 Mint to work with the 4.9 kernel quite right, so I figured I'd give this a try. My base thread is in the target area with 4.9 kernel and I'm hoping it's just the normal of me missing something(s) simple along the way.
So at this point I'm just needing to get Linuxcnc to run realtime on Mint 20.0.

Have you tried the Mint 19.3 iso with Linuxcnc ?
Quite a few users are getting good results.
All packages have been built on a machine running Mint 19.3 so no issues with Debian packages on a Ubuntu distro, and yes there are slight differences.
It’s the version I run on my own setup.
The kernel version is 4.19.106 with latest rt patches to suit.
Even on a J4105 celeron latency is no more than 38us with the sdev about 10us.
You can download the ISO run a live session and see what you think.

Using Posix RealTime
If it does say that everything is fine regarding the kernel and LinuxCNC, so the issue would be with the config.

Plenty of ideas, but start LinuxCNC from the terminal and check if it says:Hey Tommy, I tried this on my Gigabyte BRIX S with the 4.9 kernel. uname -a shows the kernel is up. I can't get Linuxcnc to run outside of simulation though, it worked on 19.3. Any ideas?

I already started down the path Beagle recommended with 19.3. Maybe it'll work right this go-round?

This is for me the most simple and easiest path and works right out of the box. Thanks Rob

Well, 19.3 had errors about 75% of the way thru while installing. I think it's becuase the Gigabyte BRIX S that I have is UEFI only, ugh. I really don't care which version of Linux this PC is on so long as it runs my machine. Gonna try back with the Mint 20.0 again and see if I can get it right this time.
