仔细读了一遍x的log，发现drm和dri出问题，导致opengl没法用，请指点一下（封贴）

鱼儿小

我是9550的显卡。

看来是ati的驱动没装好。

kernel我也重新编译了，drm也选M了，make && make modules_install也做了，可drm还是没法load，我在命令行下，modprobe drm，提示：FATAL: Error inserting drm /lib/modules/2.6.19-gentoo-r5/kernel/drivers/char/drm/drm.ko): Cannot allocate memory



x的log：

(EE) fglrx: Failed to load module "drm" (module does not exist, 0)
(EE) fglrx(0): unable to query kernel module - HW accelerated OpenGL will not work
(EE) AIGLX: Screen 0 is not DRI capable

例外，有兄弟让我下载ati-drivers的包，并sh一下，我试了：

不知所云，呵呵。。

内核编译有问题。建议察看agp芯片组选项。

有点类似我的情况，贴一下我的，显卡是 X200M，不是9550。不知道是否合适。

检查了N久，最终发现在modprobe fglrx出错，dmesg一下，看到许多未定义的函数，google后，得知应该是fglrx太旧，于是emerge最新的ati测试版驱动，再试依然不行，算了，装开源驱动吧！

又搞了N久，emerge终于完成，配置该改的也改了，startx进入x后，发现drm依然未打开（从glxinfo看到的），分析x的log，发现以下警告和错误，请大家帮我看一下，谢谢！

另：zh.gentoo-wiki.com/HOWTO_ATI_Open-Source_Drivers 中提到的Section Device中有一个BusID项目，我不知该填什么，我填写了从X的log看到的Primary device的BUSID，好象也不行，请帮我看看，谢谢。。

还有一段log，请看一下:

也许我可以帮你，我最近刚调出来。 先说说你的kernel的版本。如果是新的版本，要给官方的driver打个补丁。
我的环境是  kernel 2.6.20.3 . 官方的驱动程序要打补丁才能使用。我的电脑是T60， Ati X1300的显卡

1/ Kernel 的设置
    在这里第一要参考 http://gentoo-wiki.com/HOWTO_ATI_Drivers 的说明，完全按照这个说明设置，特别要注意的是
  

   Character Devices --->
            <M> /dev/agpgart (AGP Support)  

            <M> Intel 440LX/BX/GX , I8xx and E7x05 chip support #这理一定要选

            < > Direct Rendering Manager (XFree86 4.1.0 and higher DRI support)

   这和Thinkwiki.org中的说明矛盾，但是这里是对的，Thinkwiki是错

2/ 下载 ATI官方的驱动程序，ati-driver-installer-8.34.8-x86.x86_64.run
     选择推荐安装。此时会提示安装不成功，这是因为驱动程序对于2.6.20要打补丁才能使用
     在/lib/modules/fglrx/build_mod/中的firegl_public.c需要补丁。补丁在附件中。用法如下：
     patch firegl_public.c < fglrx-2.6.20.patch
     然后执行 make.sh， 并到上一层目录/lib/modules/fglrx/后再执行make_install.sh
3/
Now simply add the modules to /etc/modules.autoload.d/kernel-2.x where x is your kernel version.

Add the following (ORDER IS VERY IMPORTANT);
File: /etc/modules.autoload.d/kernel-2.x

agpgart
intel-agp # change intel-agp to your chipset. eg: via-agp, nvidia-agp sis-agp.
fglrx


4/reboot 牛X啦

这是那个上面的fglx 给2.6.20的patch

我的是2.6.19-r5。

你提到的patch是那里看到的？
