How to get OpenGL nVidia driver working on a linux debian system.

This wiki page is based on:

http://home.comcast.net/~andrex/Debian-nVidia/index.html

First thing you need to do is allow unstable from your sources.list file otherwise even the assistant will fail to load the nvidia-kernel-source package

 # Be carefull only for nvidia-kernel-source
 deb http://ftp.us.debian.org/debian/ unstable main non-free contrib

Another extremely important note is the matching gcc version. Be carefull that on debian most of the binary are build with gcc 3.3 , do not use gcc 3.4 or gcc 2.95 (make sure that CC is not set to anything particular).

The installation process of the nvidia library seems to be broken and noone has been working on it since two years:

See Debian bug #208198

See also http://home.comcast.net/~andrex/Debian-nVidia/troubleshooting.html Section: Hardware acceleration, aka direct rendering, doesn't work.

IMPORTANT: Seems like you need to install: xlibmesa-gl-dev AND then nvidia-glx-dev !

The Wiki page is fairly simple just linking to it

Since the debian way seems to be broken http://packages.ubuntu.com/hoary/misc/java-package, here is how to install Java on ubuntu.

Mesa, Off Screen Mesa, Mangled Mesa

Various setups:

Pure OpenGL
Pure Mesa (no hardware and it has off screen natively)
OpenGL Mangled Mesa (hardware on-screen and software off-screen)

Pure Mesa

Enable VTK_OPENGL_HAS_OSMESA
Set the following values to apropriate locations:

OSMESA_INCLUDE_DIR /.../include
OSMESA_LIBRARY     /.../lib/libOSMesa.a

OpenGL Off screen

To do hardware rendering (on screen) and software rendering (off screen) within the same application, you will have to use mangled mesa. Mangled mesa is build using all symbols mangled.

You may want to first look at article How I Mangled Mesa.

Build Mangled Mesa

The following refers to Mesa 6.2.*

Edit apropriate system configuration file. On Linux, for example, if you are building static, edit the file:

/path/to/source/config/linux-static

Edit the CFLAGS line and add the following at the end of CFLAGS and CXXFLAGS:

-DUSE_MGL_NAMESPACE

Then edit file:

/path/to/source/config/default

And rename the standard names for the libraries, for example:

# Library names (base name)
GL_LIB = MesaGL
GLU_LIB = MesaGLU
GLUT_LIB = MesaGlut
GLW_LIB = MesaGLw
OSMESA_LIB = MesaOSMesa

Setup VTK

Disable VTK_OPENGL_HAS_OSMESA

Make sure OpenGL settings are set to the hardware OpenGL library:

OPENGL_INCLUDE_DIR               /usr/include                                                                                                                           
OPENGL_gl_LIBRARY                /usr/lib/libGL.so                                                                                                                      
OPENGL_glu_LIBRARY               /usr/lib/libGLU.so

Enable VTK_USE_MANGLED_MESA

Set mangled mesa options:

MANGLED_MESA_INCLUDE_DIR        /.../include
MANGLED_MESA_LIBRARY            /.../lib/libMesaGL.a
MANGLED_OSMESA_INCLUDE_DIR      /.../include
MANGLED_OSMESA_LIBRARY          /.../lib/libMesaOSMesa.a

Use of Mangled Mesa

For all mangled mesa calls, the vtk*Mesa* classes need to be used. For example, instead of vtkRenderWindow, vtkXMesaRenderWindow must be used. The full list of classes is:

vtkXMesaRenderWindow
vtkMesaActor
vtkMesaCamera
vtkMesaImageActor
vtkMesaLight
vtkMesaProperty
vtkMesaPolyDataMapper
vtkMesaRenderer
vtkMesaTexture
vtkMesaVolumeTextureMapper2D
vtkMesaVolumeRayCastMapper
vtkMesaRayCastImageDisplayHelper
vtkMesaFreeTypeTextMapper
vtkMesaImageMapper
vtkMesaPolyDataMapper2D

To make Mangled mesa to be default, do the following at beginning of the program:

vtkGraphicsFactory::SetUseMesaClasses(1);
vtkImagingFactory::SetUseMesaClasses(1);
