[PyMOL] Slow Pymol rendering

[Chen Z. <che...@gm...>]

Dear all,

I recently upgraded to Debian 8 and I compiled the source code for pymol
1.8.2.0. However, the graphics is really slow. The information that pymol
prints out is as follows:

 Detected OpenGL version 2.0 or greater. Shaders available.
 Detected GLSL version 1.30.
 OpenGL graphics engine:
  GL_VENDOR:   nouveau
  GL_RENDERER: Gallium 0.4 on NVE7
  GL_VERSION:  3.0 Mesa 10.3.2
 Detected blacklisted graphics driver.  Disabling shaders.
 Detected 8 CPU cores.  Enabled multithreaded rendering.

I am not sure whether it is related to the driver of my graphics card. I
have a NVIDIA Corporation GK107GLM [Quadro K1000M] but I failed to install
the non free Nvidia driver. I instead used the open source nouveau.

I appreciate your inputs!

Best,
Chen
