我的是集成显卡845gl的，xorg7.0调用驱动是不是用i810

我的是用这个.不知道还有别的没有?

对的，就是用这个...
i810, i810-DC100, i810e, i815, 830M, 845G, 852GM, 855GM, 865G and 915G 都用这个。

thx,兄弟们

但是貌似没有glx，不知道为啥

这要看显卡是否支持，以及3D加速是否配置好了。
我用的显卡是855GM，3D加速是没有问题的：

$ glxinfo | grep direct
direct rendering: Yes
$ glxgears
5118 frames in 5.0 seconds = 1023.514 FPS
5107 frames in 5.0 seconds = 1021.306 FPS
5099 frames in 5.0 seconds = 1019.792 FPS
5100 frames in 5.0 seconds = 1019.811 FPS

澄清一下概念
glx是X的opengl extension，每个人都有，只要xorg.conf里指定了load "glx"
GLX (initialism for "OpenGL Extension to the X Window System") provides the glue connecting OpenGL and the X Window System: it enables programs wishing to use OpenGL to do so within a window provided by the X Window System.

GLX consists of three parts:

* An API that provides OpenGL functions to an X Window System application.
* An extension of the X protocol, which allows the client (the OpenGL application) to send 3D rendering commands to the X server (the software responsible for the display). The client and server software may run on different computers.
* An extension of the X server that receives the rendering commands from the client and either passes them on to a hardware-accelerated 3D graphics card or renders them in software, usually using the Mesa library (which is much slower).

If client and server are running on the same computer and an accelerated 3D graphics card using a suitable driver is available, the latter two components can be bypassed by DRI. In this case, the client program is then allowed to directly access the graphics hardware.

A great deal of diagnostic information about GLX, including the GLX visuals the server supports, can be found using the "glxinfo" command. The demo utility "glxgears" provides a rough estimate of the speed of the 3D rendering setup.

GLX was created by Silicon Graphics and is currently at version 1.4. GLX, with both DRI and Mesa, is included in the X.Org Foundation's version of the X Window System since X11R6.7.0, and in The XFree86 Project's version since version 4.0.

不好意思，忘了uncomment load "glx"……

复制代码

怎么845G会跟855差那么远的？下面是我的845G的参数：

1895 frames in 5.0 seconds = 378.885 FPS
1897 frames in 5.0 seconds = 379.372 FPS
1894 frames in 5.0 seconds = 378.789 FPS
1894 frames in 5.0 seconds = 378.760 FPS
1828 frames in 5.0 seconds = 365.432 FPS

不知道，845G 运行 compiz, xgl 之类的东西会不会很慢？？？

我的855GM也就300多FPS
