I will try that next time (I have another machine on which I need to install once this one is running in its place temporarily).
Tommylight wrote it as a 19.2 installation with 2.8 so I took the instructions that followed as being for 19.3 rather than the stated 19.2
Cheers
Paul

So I'm going thru trying this install again, since it was the only one that worked on my PC and I could use Linuxcnc to control the machine. Problem was that the latency was horrific with the 5.4 kernel (Mesa 7i96 board). So now I'm circling back to try to get that BRIX PC to work my table, I gave the 4.9 version of this a try. When I'm finished with the install and get it to boot into RT, the screen resolution is whacky and it will not let me change it. Is there a fix for that?

Edit: Resolution is stuck at 800x600 once I'm booted up on RT kernel.

Ok which kernel and which install medium ?
I’ve got the Mint ISO installed on a couple of different machines, a Lenovo S20 ThinkStation (Desktop) with an nVidia GPU, a Lenovo T540 laptop with an nVidia GPU, the actual machine I run my mill with has a J3355b m/b using the intel graphics and my Odroid H2+ that has intel graphics. Neither of these machines have I had graphics issues.
Unfortunately that is one of the issues with a real-time kernel and some gpus, graphics can get stuck at one mode. It also will depend on the kernel config and which drivers have been included and which haven’t.
I’ve tried to include as much graphic support in the kernels I build as I can.

Thanks Beagle, sorry about the confusion between threads lol. I'm just slamming thru til I find something that works.

I've ran the iso at the beginning of this thread. It's going onto a Gigabyte BRIX S PC (Celeron, SSD). The graphics worked perfectly with kernel 5.4.x, but seems to be at issue with 4.9.x (running this now, from post #1 this thread). The latency is very acceptable for my Mesa card with this kernel, 5.4.x it was too bad. If I can get the screen res back to something better I would like to try running the machine with it.

I can deal with the reduced screen resolution so long as this thing runs the machine smoothly. So now again I can't get Linuxcnc to run outside of a simulation, looks like it isn't working with the kernel. Remember I'm a linux/software idiot lol...

Just a quick one what is the actual BRIX you are using and what model celeron does it have ?
I tried a search for BRIX S Celeron and there's a few out there.
