Hello all, When I try to launch any of the visionegg demos, I get an error message :'pygame.error: couldn't find matching GLX visual' provoked by the line 'screen=get_default_screen()'. I checked that: - All the examples given with the pygame package work fine (but they probably do not use OpenGL). - several opengl programs (e.g. the mesa-demo programs) work fine. - The glx module is loaded (checked in /var/log/XFree86.0.log) - When I launch 'python opengl_info.py', I get a lengthy output, with some tests that fails, but nothing which seems crucial (?). Any hint? It is probably something stupid but I don't know much about OpenGL. I use visionegg-0.9.4a3. (by the way, when installing it, I got the message: error: can't copy 'data/az_el.png': doesn't exist or not a regular file ) I use the nvidia drivers: OpenGL information returned from OpenGL drivers: GL_VENDOR = NVIDIA Corporation GL_RENDERER = GeForce4 440 Go/AGP/SSE2 GL_VERSION = 1.3.1 NVIDIA 31.23 Christophe Pallier www.pallier.org ====================================== The Vision Egg mailing list Archives: //www.freelists.org/archives/visionegg Website: http://www.visionegg.org/mailinglist.html
