After running the Panda3D installer for a freshly git cloned and compiled 1.9.0 dev source code set, I am getting an error printed to the console for the “Hello World” example. I do get the “Hello World” Panda3D grey window displayed though.
I am taking a totally newbie shot-in-the-dark here based on a similar error with Java’s “lwjgl”. It was an enumeration error for opengl in java’s “lwjgl”. It regarded my “video card” (onboard chip actually) which does not have pixel shader hardware and the lwjgl library doesn’t return a false or -1 for a non-existant pixel shader version, it returned and exception.
Googling Pand3d and :display:gsg:glgsg(error) gave results where some alluded to video card drivers (impling better support for pixel shaders) and others suggesting to not using opengl in Config.prc but to use the other renderers instead. Has my investigation led me in to not use opengl due to lack of pixel shaders (on this system)? I ask this because I am pretty sure I ran the Asteroids example through the browser on the web fine before this machine had a crash and full reinstall of the os (and all).

Video card is onboard Intel 82865G which does not support any Pixel Shader versions (but has Direct X 9.0c support). No updated video drivers available for a few years now, which is to say the latest is loaded.
