Hi there,
I’m trying to open the spectras from my project and seems like an OPENGL type of errror. I updated to the last version of CCPNMR this morning (18/11/2025) and really appreciate if anyone can help me.
I’m attaching a printscreen.
Renan
Hi Renan,
sorry about this.
What operating system (and version) are you using?
And can you give us the final bit of the traceback, please? It seems to be cut off at the bottom.
Thanks!
Vicky
Hi Vicky,
Sure. I’m attaching the full error here to make it easier to navigate. I tried to open a 1H-15N HSQC but happens with all other spectras.
I’m operating with this version of Linux.
NAME=“Ubuntu”
VERSION_ID=“24.04”
VERSION=“24.04.3 LTS (Noble Numbat)”
It was working couple days ago… don’t know if it was an recently update.
Thanks,
Renan

Hi Renan,
The last time I encountered a problem with OpenGL, I found a successful workaround.
In a shell, run:
export PYOPENGL_PLATFORM=posix
Then, run CCPN as normal.
Hope it helps!
Best wishes,
Rodolpho
Hi Rodolpho,
It did works. Thanks for your tip. Not sure why this happened, since it was everything fine like couple days ago.
Cheers,
Renan

Hi Rodolpho and Vicky,
If I don’t run the command every time that I open ccpnmr, it won’t show the spectras and give the same error.
Any other recommendations?
Best wishes,
Renan
Hi Renan,
we were actually wondering what graphics you are using. At the moment we are not compatible with Weyland, and we wondered whether Rodlopho’s command is in fact a workaround for using Weyland.
Vicky
You should be able to add the export to your .bashrc etc so it gets run every time you start a terminal. what shell are
You using ie if you type echo $SHELL what do you get ?

Hi Vicky and Gary,
@varioustoxins when I type echo $shell it doesn’t give me nothing. Maybe its something wrong happening? My concern is bc it was running perfectly before the last update.. but I will put on bashrc. Thanks!
@VickyH I typed lspci -k | grep -EA3 'VGA|3D|Display and it gaves me:

Make sure the capitalisation is right SHELL has to be upper case…

The put the
export PYOPENGL_PLATFORM=posix
In .bashrc
Close all terminal windows open a new one and see if thats a permanent fix for you
