Probe Basic - Crashing on startup, bad window parameter

Hey guys thanks in advance for any help with this. I'm in the process of building my first CNC machine; I'm familiar with CNC machines but not as much with linux, so I may just be missing something obvious.

LinuxCNC is running fine, latency seems good, and I was able to communicate with the MESA Ethernet board. Opening other QtPyVCP GUI's such as QTdragon works fine, but when I try to open a Probe Basic sim or custom config it crashes before anything is displayed.

I originally set everything up on Debian Buster with LinuxCNC 2.8.4, but after having no luck with that and thinking it may be a Python 2 / Python 3 issue, I re-installed with Bookworm and tried a few different installation methods for Probe Basic but I'm still getting the same error.

I'm thinking maybe this is due to not running it in a virtual enviorment? Would I need to install it inside a virtual enviorment or is there another way? Running a virtual enviorment seems like it would be less robust, but I'd love to hear otherwise if that's the case.

Getting an error from the forum editor "You have too many links, please decrease them" so I'll upload a screenshot of the end of the error log and try to add the whole thing later.


 

how did you install? the only acceptable installation method is the deb installation currently for machine use in debian 12 which is found here:

forum.linuxcnc.org/qtpyvcp/48373-qtpyvcp...llation-files-inside

and this is designed to work only with debian 12 xfce, it may work on other flavors of linuxcnc, but that is on the user to untangle and make work, we only support xfce installation.

Thanks for the quick reply!

I installed following the instructions and file you linked to (on March 9th), with the only difference being Gnome instead of XFCE. Perhaps that's the issue, but I was getting the same error code when I tried Debian 10 and LinuxCNC 2.8.4 with older instructions.

Thanks

are you using the non free alpha2 cdnetinst image for debian 12?

www.debian.org/devel/debian-installer/

that should have all the non free firmware for any upgraded graphics cards. if still an issue it may be an issue with your graphics card compatibility. have you tried using the onboard graphics? I am running a HP elite 8300 usdt with its on board with great results and no issues here.

Got it working!

Seems like it was from using Gnome instead of the supported XFCE, and wayland was casuing the error. Disabling wayland did the trick and all is working now on Gnome.

Thanks again!

This is correct. Linuxcnc does not like wayland so xfce (an  Xorg system) solves the issue
There have been changes recently to the code and it seems to be OK here on Debian Bookworm installed deba.

adding this line to your .profile file in your home folder should also fix it after a logout/loginRef: github.com/LinuxCNC/linuxcnc/issues/2264

Thanks rodw! Good info to have
