Asus Prime A520M-K No X Window system

I believe most non Nvidia cards work fine without screwing up real time. Most onboard graphics are usually ok as well. Nvidia drivers often are a problem with real time.

At this point in order to preserve my sanity I'm thinking of installing on a Raspberry Pi 4 8GB. Will the Pi keep up?

I have tried installing LinuxCNC on three video cards and the onboard video. None run X after the install.

I have also tried to install Fedora 36, Ubuntu 22.04 and Debian 11.4.0. None ran X after the install. All installs including LinuxCNC were using the graphics install.

One non-LinuxCNC install ran X during the install in 2189 mode.

Currently running a memory test, but it has shown no errors in two passes, working on the last two now.

I had LinuxCNC running on this motherboard last September. After that is was powered down until recently.

Perhaps a bad motherboard?

I managed to get LinuxCNC 2.8.2 to install and run, but without X. The three graphics cards I have laying around are NVidia cards and I suspect the drivers have to be downloaded and insalled for them. Either way, the realtime kernel is apparently less than fond of them.

I have ordered this card: smile.amazon.com/dp/B006V2IZ30?psc=1&ref...dt_b_product_details a Radion 6350 card. We will see how that goes this afternoon.

For what it is worth, the ISO image for Raspberry Pi will not boot on my Pi 4.

The cost to go to Mach4 is about $800, Windows 10 + Mach4 + a new stepper driver interface card. I had LinuxCNC running with my Sherline Mill a year ago, so sticking with that hardware/software is not only a lot cheaper, but perhaps a bit less traumatic (though after this goat rope, the jury is out).

What kind of Raspberry do you have?

What ISO image did you use?

Raspberry Pi 4

Motherboard (although still being sold) has a Radeon graphics card too old to be supported by Debian 10 distro, or any repo that installs with it. Going to AMD to download yielded that it was too old to be supported by AMD.

Bought new Radeon card. It is too new to be supported in Debian 10 insalled libraries and repos.

But, it works in 1080 mode, which is good enough for now. I'm hoping that the next release of LinuxCNC will support it directly.

Thanks for the help!

To find out what type of Raspberry you have, you need to run this command from the terminal

cat /sys/firmware/devicetree/base/model

Try the 64-bit version 2.9.0pre which you can find at this link

Can you explain again what hardware you have? I tried to look into this but there seems to be no such thing as a "Radeon HD 5880" graphics card. There's a Radeon HD 5870, released in 2009 (which still has active support in the kernel BTW). And the AMD A520 chipset doesn't seem to have any kind of built-in graphics at all - but it does support AMD "APUs", i.e. CPUs with built-in graphics.

I general, support for old hardware does not get removed from the linux kernel once it's in there - that's one of the great things about Linux: it doesn't force you to buy new hardware on updates, with very few exceptions.
