when I try to run a QtQuick application from QtCeator, I got this errors:
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
QGLXContext: Failed to create dummy context
QRhiGles2: Failed to create temporary context
QRhiGles2: Failed to create context
Failed to create RHI (backend 2)
Failed to initialize graphics backend for OpenGL
after investigation, I think the problem is Nvidia Driver because I have no problem with Nouveau Driver (the problem only exist with QtCreator)
for information:
ldd Qt/Tools/QtCreator/bin/qtcreator | grep libGL
libGL.so.1 => /lib/x86_64-linux-gnu/libGL.so.1 (0x00007fcdf5a19000)
and:
find /usr -iname "*libGL.so*" -exec ls -l -- {} +
