Problem installing Nvidia driver on a real time kernel

Hello everyone,

I am working on installing drivers for the nvidia graphics card on my ubuntu 12.04. I found out that the Nvidia driver does not have support for real-time kernels. But, in order to use linuxcnc I need RT kernels.
I would like to know any alternatives for installing the Nvidia drivers that are supported by the real-time kernels.
All I need is the right kind of OS for linuxcnc and good graphics support(Nvidia/AMD)

That is the enemy territory full of landmines !
Both laptops that i use daily have NVIDIA besides Intel graphic cards so i can choose what to use, and for the big PC's i can choose between Nvidia 1060 or AMD RX580, but since i use Linuxcnc on all of them i have to be content with the Intel graphic on laptops and the RX580 on the big ones.
Also the R580 driver will not work with Preempt-RT, but some 3D stuff works quite nicely with the included Linux drivers, Heaven benchmark runs just fine, albeit a bit slower than it can with the proprietary drivers.

A CNC mashine PC does not need this kind of Graphics
it is BESTknown to get a simple very low coat Graphics card to be installed to the system

try to get one at ebay around 10USD if you realy want to avoid big backs

I need that one of those as i have 4 monitors attached to it, 1920x1200 each vertically aligned so i got a 4800x1920 screen.

I would like to know which recent AMD GPU works with Debian 9 on a preempt-RT kernel?

I use Linux Mint with Mate.

My solution to the Nvidia issue would be to unplug the Nvidia card and use it in your CAM system, and keep it as far away from LinuxCNC as possible...
