Interesting, thanks for tracking this down! Andreas, if this turns out to work for you, I could add this to Mnemosyne’s code, provided there are no side-effects/issues for other linux distributions.
The file you need to add these lines to is ‘mnemosyne’, just add them at the top.

However, the version compiled from the tarball generated the exact same error messages. :-( (I haven't deinstalled the package, but normally they shouldn't interfere) Best regards, Andreas It sounds like this issue may have existed in Ubuntu some time ago, caused by a mismatch between an installed NVidia graphics driver conflicting with the libGL.so build: https://forum.qt.io/topic/81328/ubuntu-qopenglshaderprogram-shader-program-is-not-linked/2 The workaround there was to add these lines during program initialisation: if sys.platform.startswith('linux'): from OpenGL import GL Am Sonntag, 23.

Core file will not be generated. According to my analysis, there are two potential problems: a) the "device not open" might indicate that some (config) file is either not writeable, or the directory is not existing b) the "shader" error I don't understand at all. It might be related to my graphics card driver, but I have not made any progress on that end. Any idea would be highly appreciated!
