Segmentation Fault (core dumped)

[markiscoding]

I’m just starting out with Panda3D and getting this error in terminal:

Known pipe types:
glxGraphicsPipe
(all display modules loaded.)
:pgraph(warning): No bin named ground; creating default bin.
:pgraph(warning): No bin named shadow; creating default bin.
Segmentation fault (core dumped)

When I look at the output window graphics are all messed up but I’m sure my GPU works just fine. Any suggestions on how to fix this ?

Which precise version of Panda3D did you install? Try either:

import panda3d
print(panda3d.__version__)

Or:

from panda3d.core import PandaSystem
print(PandaSystem.getGitCommit())

What GPU do you have? Do you have the latest video card drivers? Could you attach the output of glxinfo?

print(PandaSystem.getGitCommit()) gave me 5c9705c21c551c072dc0861965d6e8f4b7cbe657
print(panda3d.__version__) gave me an error saying “panda3d has no method version”

Here’s output from glxinfo (I included relevant data only):

My GPU is officially called AMD Radeon R4/R5. Ubuntu is using open source driver to make it work.
