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

Not that i am aware of.

I can't seem to get this system back to life. I even followed the gnispel.com instructions and went through the lengthy build and make process. After finished, and the correct kernel is loaded, I no longer have a system that finds the nVidia graphics card. No nvidia drivers are loaded, the system is running slowly & there's seems to be no version that functions.

Some forums suggest disabling secure boot in the Bios, which I did before starting anything else, I've rebooted a bunch and the nVidia drivers that work fine without patching the kernel no longer work after following the gnispel instructions.

I just figured out how to DISable the default UEFI drives in the Bios. I didn't realize that those were selectable & could just be removed. Re-doing for the umpteenth time. Grrr.....

Someone HAS to start pruning these form topics. Those where the first post says something like "Finally got it working...", only to find out that 38 pages later the last post says "...I'll have to figure that out..." are just time-wasting garbage. They should all be moved to a folder of failures so no one gets stung by them. If they don't work, it should be clearly stated in the title or the whole topic should have a warning color or something. It's way too frustrating to sift through all the nonsense.

Everything seems to work if I set the primary drive for install & follow your instructions in the first post, except it seems to break the drivers for my nVidia GeForce 1050 TI board. I have a running, default RT-Prempt kernel, latency is 4.5 ns, but everything is 640 x 480 and unusable.

Tried using all 4 of the available drivers in the Linux Mint drivers settings and none of them fix this issue.

It's been mentioned a lot on this forum and on some others that Nvidia drivers do not play nice with real time kernels. That is due to the power saving features in those cards, same with plenty of AMD ones.
I did manage to get things working with an RTX 1060/6GB and RX580/8GB, but the latency goes to hell in a hand basket. Still usable with RX580 but not with NVIDIA.
I never install proprietary drivers on Linuxcnc machines, although most of my PC's and Laptops have Nvidia cards on them.
From experience, chances are bigger to use an AMD card than Nvidia, as AMD does not care much about electronic design guidelines, case in point, older RX480 would draw 9A from the PCI-E slot at 12V, while the max allowed is 75W or a smidge over 6A.
However you look at it, that is a stab in the dark, even the same card from diferent manufacturers migh or might not work.
My advice, do not bother with it.
The time and frustration you have put into it could have been forgone by buying another used PC for 50 to 100$. Dell and HP enterprise edition used ones work perfectly with Linuxcnc, i tested over 30 types of them.
