ML能正确的驱动915的显卡，只是默认的分辨率是1024x768, 如果要支持宽屏的话需要一个915的补丁。在Intel下的那个dri我没有搞定，用的是别外一个，附在后面。
1. 将这个补丁编译后，运行（用root运行）
# 915resolution -l
Intel 915GM VBIOS Hack : version 0.1
Chipset: 915GM
Mode 30 : 640x480, 8 bits/pixel
Mode 32 : 800x600, 8 bits/pixel
Mode 34 : 1024x768, 8 bits/pixel
Mode 38 : 1280x1024, 8 bits/pixel
Mode 3a : 1600x1200, 8 bits/pixel
Mode 3c : 1280x800, 8 bits/pixel
Mode 41 : 640x480, 16 bits/pixel
Mode 43 : 800x600, 16 bits/pixel
Mode 45 : 1024x768, 16 bits/pixel
Mode 49 : 1280x1024, 16 bits/pixel
Mode 4b : 1600x1200, 16 bits/pixel
Mode 4d : 1280x800, 16 bits/pixel
Mode 50 : 640x480, 32 bits/pixel
Mode 52 : 800x600, 32 bits/pixel
Mode 54 : 1024x768, 32 bits/pixel
Mode 58 : 1280x1024, 32 bits/pixel
Mode 5a : 1600x1200, 32 bits/pixel
Mode 5c :1900x1600, 32 bits/pixel
会显示上面的目前能用的分辩率，找一个我们用不上的，比如5c 来改一下：
# 915resolution 5c 1280 800
这时在用-l看，就成了：
Mode 5c : 1280x800, 32 bits/pixel
把刚才运行的命令加了/etc/rc.d/rc.local中，就不用每次都手工运行了。
2.只做上面的不行，还要配xorg.conf
将Section "Screen" 节中的各个 Modes中加上 "1280x800"：
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1280x800"
EndSubSection
3.如果这时启动的话还是1024x768在xorg的log中会提示找不到mode name:
要xorg.conf中加下Modes小节，默认的好像没有,
先运行# gtf 1280 800 60 //分辩率和刷新率，LCD都用60就行了
会得到如下的行：
# 1280x800 @ 60.00 Hz (GTF) hsync: 49.68 kHz; pclk: 83.46 MHz
Modeline "1280x800_60.00"83.461280 1344 1480 1680800 801 804 828-HSync +Vsync
把它加到xorg.conf的Modes中 就行了，如下：
Section "Modes"
Identifier "Modes"
#gtf 1280 800 60
# 1280x800 @ 60.00 Hz (GTF) hsync: 49.68 kHz; pclk: 83.46 MHz
Modeline "1280x800_60.00"83.461280 1344 1480 1680800 801 804 828-HSync +Vsync
EndSection
注意： 在Modeline 后的是"1280x800_60.00" 而在SubSection "Display" 的Modes 是没有后面的_60.00的，这开始就在这搞了半天 :oops:
====================
不知道怎么传文件，以下是源码，用gcc 915resolution.c -o 915resolution 编译就行了

----------------------------------------- 好文章，收藏了。不过想顺便问问 intel的dri你说没有搞定 ，你都怎么搞了？我也遇到了同样的问题 终于搞定拉
简单总结一下 :mrgreen:
1.首先安装ML的时候，在最后配置显卡的时候一定要选，一个合适的。例如我的是DELL的本子，我就选 了DELL LCD pancle的 1280*1024的。显卡也一定要选，例如我的是Intel915就选了。之后的选择分辨率把1024*768 1280*1024都选上.测试通过后选择完成安装
2进入X发现 分辨率还在1024*768.这是因为还上不到1280*1024.这个时候用楼上大915那个补丁，写入rc。local文件。 同时改xorg。conf把1280*1024 改成 1280*800
3不用安装任何驱动和补丁，直接还是在xorg。conf里面加入DRI的相关选项就可以打开3D了
4 测试 glxinfo glxgears
name of display: :0.0
display: :0screen: 0
direct rendering: Yes
server glx vendor string: SGI
server glx version string: 1.2
server glx extensions:
6320 frames in 5.0 seconds = 1263.994 FPS
6257 frames in 5.0 seconds = 1251.230 FPS
6317 frames in 5.0 seconds = 1263.243 FPS
6250 frames in 5.0 seconds = 1249.954 FPS
6322 frames in 5.0 seconds = 1264.275 FPS
6250 frames in 5.0 seconds = 1249.850 FPS
基本效果还是比较明显的。 终于搞定拉
3不用安装任何驱动和补丁，直接还是在xorg。conf里面加入DRI的相关选项就可以打开3D了
请问怎样在xorg.conf里进行修改加入dri相关选项以打开3D？能不能说的详细些啊？ 请问怎样在xorg.conf里进行修改加入dri相关选项以打开3D？能不能说的详细些啊？
下回切换到linux里面看看xorg.conf之后贴出来。先占个位置。 Section "Device"
Identifier "Videocard0"
Driver "i810"
VendorName "Videocard vendor"
BoardName "Intel 915"
VideoRam 131072
Option "DRI" "true"
Option "Composite" "Enable"
Option "RENDER" "Enable"
EndSection
Section "DRI"
Mode 0666
EndSection 是不是重新编译一下内核的话，把显卡声卡网卡等统统编进内核的话就没有这些麻烦了吧。
？ :!::?::?::?:
严重错误！安装第三方驱动，则内核里相应部分通常都要是模块，否则驱动程序因不能替换老模块，会报错。 这篇应该加个精华，
唯一一个介绍intel显卡3d驱动有效的好贴。 按照楼主的方法试了，修改xorg。conf，还是打不开3d,我的显卡是852集成显卡 按照楼主的方法试了，修改xorg。conf，还是打不开3d,我的显卡是852集成显卡
是不是使用root用户。
楼主也只是root才有加速的。 是呀，我一直使用root用户的，可还是不行啊，运行glxgears，只有570多FPS 把你的
glxinfo
运行结果

回复 1# chenlei9907 的帖子
我也是相同的电脑，出现了完全相同的现象。而且丢了光盘，弄了半天没搞好。看了大侠的回答，很高深，不懂。后来一下子解决了。其实处理很简单。
到dell的网站，根据自己的电脑型号选取相应的型号：笔记本，inspriron,630m，XP,
然后它在显卡上有三个驱动程序，分别是推荐的，可选的，紧急的。按照经验，我只安装了
推荐的和紧急的，结果不行，后来再安装可选的程序，结果一下子就解决了。
