glxgears works fine, and glxinfo seems to be OK, even I have direct rendering. I have Ubuntu 9.10 and an ATI radeon card. This is odd, because with Ubuntu 8.04 I don't had problems (And I had Blender without problems). I think this is a bug on Ubuntu.

Hi!

First, try glxgears and look if it works. Second, look at the output of glxinfo. Third, what system and architecture are you on, which GPU and drivers are you using?

I had a funny issue with OpenGL a while ago on my Ubuntu box. Basically I got an X.Org update which as a sideffect reset the symlink to libGL.so. I was searching for hours for bugs in my code, not realizing that some default libGL.so was used instead the one of my NVIDIA driver.

Cheers,
TOM

Hm.. the segfault is in glGetError. It sounds like this bug, where glGetError segfaults if there is no current context (maybe try the example code given there?)

This example crash too :(

However, there may be something going wrong on GNUstep's side as well. Do other OpenGL apps work on your system?

I install Oolite and Blender. Oolite run, but after some seconds crash. Blender can't run: Segmentation fault. This seems to be a bug on Ubuntu and Debian.
