安装nvidia for FreeBSD驱动的一点儿注解[zt]

安装nvidia for FreeBSD驱动的一点儿注解
http://blog.chinaunix.net/u/12258/showart_477036.html
在一台装有 GeForce 6600 的机器上安装nvidia驱动，使用的是如下ports

/usr/ports/x11/nvidia-driver
/usr/ports/x11/nvidia-settings
/usr/ports/x11/nvidia-xconfig

安装nvidia-driver时，从驱动文件下载到make install都正常，没有安装linux兼容部分，发现在安装过程中并没有完成nvidia.ko的配置过程，有些纳闷，权宜之计是手动在/boot/loader.conf中添加：

nvidia_load="YES"

启 动kdm，可以看到nvidia的欢迎画面了，利用nvidia-xconfig完成了xorg.conf的配置，启动kde后运行nvidia- settings，设置了刷新率，这个刷新率的设置是可以保存在xorg.conf中的，所有工作做完以后，我的xorg.conf是这样的。

为了测试3D加速效果，安装了如下ports

/usr/ports/graphics/mesa-demos

glxinfo glxpears等测试程序都是在这个ports中，但是在make时，在一些测试程序中报错无法继续进行下去，主要是一些 ...MESA 函数，查看 /usr/local/include/GL/glx.h 文件，里面也不存在对应的函数，费了一番周折进行了修改，但是整体编译还是不成功。

细究了一下 GL 对应的头文件，发现在nvidia驱动安装以后，nvidia不同程度的覆盖了原来系统的MESA3D的一些文件。

/usr/local/lib/libGL.so.1的pkg_info信息如下：

both libGL-7.0.1 and nvidia-driver-100.14.19，也就是两个ports都包含这个，从日期上看，nvidia的覆盖了原来的。

libGL-7.0.1的文件列表如下：

Information for libGL-7.0.1:

Files:
/usr/local/include/GL/gl.h
/usr/local/include/GL/glext.h
/usr/local/include/GL/glx.h
/usr/local/include/GL/glxext.h
/usr/local/lib/libGL.so
/usr/local/lib/libGL.so.1

目录下的libGLU.so.1没有被覆盖，它属于libGLU-7.0.1软件包

文件列表如下：

Information for libGLU-7.0.1:

Files:
/usr/local/include/GL/glu.h
/usr/local/lib/libGLU.so
/usr/local/lib/libGLU.so.1

对比nvidia的文件列表可以发现，nvidia替换了libGL.so.1这个库，所用的头文件放在了

/usr/local/share/doc/NVIDIA_GLX-1.0/gl.h
/usr/local/share/doc/NVIDIA_GLX-1.0/glext.h
/usr/local/share/doc/NVIDIA_GLX-1.0/glx.h
/usr/local/share/doc/NVIDIA_GLX-1.0/glxtokens.h

我想这可能是mesa-demos没有安装成功的一个原因，但没有具体的确定

小节：OPENGL的库还是蛮复杂的，感觉里面也是有不少的陷阱

PS：混合特效一直不太成功，在xorg.conf添加了options也不行，不知道是kde 3.5.8还是X以及nvidia的问题！

附上nvidia-driver的文件列表，以后参考:-)
