Hello rdb In this post he python environment variables are printed in 2 cases : python and panda3D execution. Below you will find the environment variables when it is launched with python, the display in wx is OK .....$ python ./testWX.py Known pipe types: glxGraphicsPipe (all display modules loaded.)
