(Solved) Difficulties Setting Up Probe Basic

Understood. In that case, I will swap monitors and report back.

-Tanner Frisby

I'm pretty sure the built in Intel graphics of Core-Duo vintage
PCs do not support Open GL 2.1 (I had to add a graphics card
to try ProbeBasic on my old HP DC7800 which is similar to your dell)

The Ethernet issue is likely because you did not setup a static IP address
on the Ethernet port (10.10.10.100 suggested if the 7I76E is at 10.10.10.10)

Greetings all,
I switched to a monitor with the correct resolution (HP LV2311). Sadly, i still cannot launch DISPLAY = probe_basic. Just to verify, I am able to launch with the only change being DISPLAY = axis. 

Attached is my most recent error report. I looked at it briefly and it appears to be largely the same. After updating/upgrading from terminal, it looks like I went from 2.8.0 to 2.8.2: LINUXCNC - 2.8.0-pre3-68-ga88536efc2-20-gacab27a90
SMP PREEMPT RT Debian 4.9.228-1 (2020272-2 (2021-07-0519)
Also, my monitor change is reflected: display size: 1280x10241920x1080 pixels (338x270508x286 millimeters)
It appears a fair bit changed in the "traceback (most recent call last)" section, but I can't determine if it is relevant. 



Furthermore, here is some information about my OpenGL compatability:

glxinfo | grep 'version'
server glx version string: 1.4
client glx version string: 1.4
GLX version: 1.4
    Max core profile version: 0.0
    Max compat profile version: 2.1
    Max GLES1 profile version: 1.1
    Max GLES[23] profile version: 2.0
OpenGL version string: 2.1 Mesa 13.0.6
OpenGL shading language version string: 1.20
OpenGL ES profile version string: OpenGL ES 2.0 Mesa 13.0.6
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 1.0.16

What should my next troubleshooting steps be?

First test is to try running the simulation version of probe basic to determine if it's hardware or software

I opened LinuxCNC and selected:
My Configurations
   > probe_basic
      > probe_basic
         > probe_basic
            <OK>

It terminated with the attached error message:

 

I think the pertinent portion of the error message is as follows:

ERROR: In /work/standalone-x64-build/VTK-source/Rendering/OpenGL2/vtkOpenGLRenderWindow.cxx, line 797
vtkXOpenGLRenderWindow (0x562ee11d8820): GL version 2.1 with the gpu_shader4 extension is not supported by your graphics driver but is required for the new OpenGL rendering backend. Please update your OpenGL driver. If you are using Mesa please make sure you have version 10.6.5 or later and make sure your driver in Mesa supports OpenGL 3.2.


Which implies to me that it's time to buy a graphics card. Please advise.

How did you install probe basic and what version of linuxcnc are you running?
