Unable to find any valuable Cutbuffer provider (Arch Linux/Manjaro)

Just noticed this in the terminal. Could this be related to the broken kivy on ubuntu?

Have you tried reinstalling or updating Kivy?

Thank you

Nope, I’ve seen it again in the terminal, but GC seems to run normal. I want to figgure out what triggers the message.

It looks similar to what Kivy on Windows does when it doesn’t like the open GL it finds.

Thank you

The startup look fine and all green. It happens at some point during the use of GC. I’ve been moving around, loading diferent files, bit-up runs, but still not found how to trigger the error message.

I think this is different than the Ubuntu display issue. Xsel and xclip are the the utilities for Xorg clipboard - copy and paste, I believe. Are xsel and xclip packages installed?

The fuss might be about an image not found? The message is triggered by the ‘calibrate’ button. In the video at 0:45


Edit: Warning, don’t try to watch 48 minutes of calibrating! I was interrupted a few times, needed to get a drink, needed to carry some drinks away, the cats were hungry and I have no slim video editor on linux!

It looks like the extension on that image is all caps…could this be our image file extension on Linux nemesis again?

It’s fixed and merged. This is 1.03
Edit: Will try the 1.07 also tonight
Edit2: replace ‘tonight’ with ‘in the morning’

I too ran into those 3 .JPG references when I went back to v1.03 recently for testing. We’ve fixed a lot of things since then!

Yes, in 1.07, 2 made it back in the code.

/GroundControl-1.07/groundcontrol.kv:752: source: “./Documentation/Calibrate Machine Dimensions/Quadrilateral Kinematics.JPG”
/GroundControl-1.07/groundcontrol.kv:754: source: “./Documentation/Calibrate Machine Dimensions/Triangular Kinematics.JPG”

However the terminal error is unrelated to the picture one. It is for sure some python or kivy thing. It sowed up with 1.07 as well and I had not started calibration. Need to dig more. Perhaps some module with version inconsistency among linux flavours like we had with pyserial.

WOOOOOOOOOOO!!! Great collaboration!

Is there any way we could check that an print a warning the way we do with pyserial versions?
