[Trisquel-users] OpenGL problem

[mtsio]

Hi,

I'm trying to run an OpenGL program from a tutorial and I get the following  
errors:

X Error of failed request:  BadRequest (invalid request code or no such  
operation)
  Major opcode of failed request:  153 (GLX)
  Minor opcode of failed request:  34 ()
  Serial number of failed request:  36
  Current serial number in output stream:  35

Any ideas?
Thanks
