说了半天还没有说到正题，笔者的笔记本是ati独立显卡，当初买笔记本时就是考虑只买独立显卡的笔记本，结果现在给自己制造了不少的麻烦，以前在《Linux应用心得》、《终于尝试了Fedora7》和《太帅了，3D》等文中曾经提到，在以前fedora5至fedora8系统的安装过程中，一直为解决ati显卡驱动和系统的3d效果的兼容性作斗争，一直持续到现在（当然现在也在继续作）。

fedora10的发布，的确欢欣鼓舞，特别fedora的官方网站提到对ati显卡的支持性将更好、更快，当时fedora10在笔者工作的笔记本上已经扎根了，但是笔者的个人笔记本上却是犹豫不决。fedora8实在太棒了，解决了笔者很多的问题。可以说fedora8是当时以往linux桌面操作系统最优秀且最经典的一个。但是fedora10也同样优秀，在长期的工作当中，体验了fedora10的乐趣，于是下决心升级了。

升级很容易，直接硬盘挂载iso就可以了，这里升级安装fedora10的废话就不多说了。
升级完成之后，打开软件正常不，发现openoffice打不开，提示错误：

Xlib:  extension "RANDR" missing on display ":0.0".

使用glxgears和fgl_glxgears都会显示：

X Error: BadRequest (invalid request code or no such operation) 1
Extension: 143 (Uknown extension)
Minor opcode: 19 (Unknown request)
Resource id: 0x17
amdcccle: xcb_io.c:461: _XRead: Assertion `dpy->xcb->reply_data != 0' failed.
Aborted

重新安装ati官方最新驱动，运行命令：

amdcccle

提示和上面一样的错误，仍然在网上Google，发现了一篇Fresh install of Fedora 10. OO3 crashes. randr，此篇帖子的jjcf89、acknak和sdoolan给出了比较中肯的建议，特别是最后sdoolan朋友的最后一回贴，重新点燃了对ati斗争的欲望，于是在gnome终端上输入：

export SAL_NOOPENGL=true

openoffice启动啦~，对笔者来说，是件惊喜的事情，但是事情没有解决，ati仍然显示不了3d效果，成功就在眼前，于是继续操作
1，备份原来/etc/X11/xorg.conf；
2，在终端下运行命令：

system-config-display

重新设置分辨率和刷新频率，如果没有安装这个命令，可以使用yum进行安装；
3，接着安装最新的ati显卡驱动ati-driver-installer-9-3-x86.x86_64.run；
4，显卡驱动安装完成之后，运行命令：

aticonfig --dtop=horizontal --overlay-on=1
aticonfig --desktop-setup=horizontal
aticonfig --initial=dual-head --screen-layout=right

5，重启计算机。
启动之后，发现漂亮的3d界面出来了，而且不用修改SAL_NOOPENGL的值，ooo也可以启动了，不会发生core dump了。

笔者生成的xorg.conf配置文件如下：
