LinuxCNC on Linux Mint 19

Hi John. This install breaks nVidia display board drivers. I've been unable to follow these instructions with Linux Mint 19.3 and have a working video card. Driver manager shows that I've selected the recommended, proprietary driver - nvidia-driver-435, but none of the settings work and executing nvidia-settings from terminal produces errors saying that no video drivers are loaded.

None of the RT_PREEMPT nor RTAI kernels play well with the nvidia drivers.

It is best not to install any nvidiia proprietary drivers.

If you want to use Mint I have made some fully installable images.
Mate with either RTAI or RT_PREEMPT are 19.2
XFCE with either RTAI or RT_PREEMPT are 19.3

I'm currently typing this from Mate 19.2 with RT_PREEMPT on a T530 Thinkpad without any of the proprietary drivers drivers for the enabled nvidia card. The T530 has intel on board and NVS 5400M card.

Heres a link to the UEFI image forum.linuxcnc.org/9-installing-linuxcnc...xcnc?start=80#158595

If you need to build 2.9 at the moment this is the branch you'll want

Just tried to install the RT kernel on Mint 19.3. This is on a Dual core AMD Phenom II X2, but had similar results on a AMD 8 core processor. When I get to the instruction "sudo make modules-install" I get a "cannot use "config-stack-validation"=y, install lib-dev, libelf-devel, or elfutils-libelf-devel". This is one of my first builds outside of using the downloadable packages on the Linuxcnc website, so I don't really know what to do next.

Did you try this:
forum.linuxcnc.org/9-installing-linuxcnc...nd-easy-installation
or for Debian 10
forum.linuxcnc.org/9-installing-linuxcnc...ick-and-easy-install
Or is there a reason you want to build your own kernel ?

I was trying to use the gnipsel.com/linuxcnc/uspace/linuxmint19-rt.html site to install and run Linuxcnc on Mint 19.3. If I understand that website, I need to make the RT kernel first, then install Linuxcnc in that "build". I have never liked the Debians since Linuxcnc went from Ubuntu, so I wanted something different, and wanted to do something to "stretch" myself. If what I am doing is unwise or just wrong, please let me know. I did try the "quick and easy" file download on the AMD 8 core processor, but it failed. I tried this a week or 2 ago, and then I tried the route of the gnipsel.com/linuxcnc/uspace/linuxmint19-rt.html . If I recall correctly, I couldn't reboot on that drive after trying it.

I just see no reason for building the kernel. It was necessary when Mint 18 came out till 19.1.
And that quick and easy tutorial never fails, just be sure to get the right files.
