DIR图形加速问题以及怎么中途换显卡
大家好，我是REDHAT 9.0，2.4.30，显卡是很老的ATI Mach64 3D RageIIC，我装了Mesa6.4.2，还有DRM什么东西的（真烦），因为我现在用的一个程序需要图形加速，所以我就想办法装啊，在ATI的官网上也没有这个显卡的驱动，好像只能靠一个DRI项目来搞，我也不确定能不能加。
关键是那个安装说明写的乱七八糟的，我不知道到底怎么装。而且我也编译过了Mesa+DRM，还是3D Rendering is No.
我快疯了，中途还把X搞得无法启动。现在走另一条路，重新编译kernel把DRI选项去了，再装DRM，如果不行，我要换卡了，
也就是另一个问题，如果我换张卡，怎么确保X窗口不会进不去？
还有就是，如果有人知道怎么搞定DRI，我是说针对老显卡的，麻烦说一下。
谢谢！ 现在这个B卡运行glxgears，才140FPS，如果你死劲儿拉动其他窗口，齿轮就不动了，然后就是17FPS。fainttttttt 这里很多人都是用 redhat 9的一律不回答.
换一个至少 2004 年出的 linux , 基本上你的显卡是直接安装好驱动的. 我当然也想用Fedora，只是，你知道很东东西新的容易出问题，一般都是2个系统，但是我的系统还连着数据采集卡和马达之类的，我不确定转到2.6是不是OK，也许我再去要个硬盘再说。 >>新的容易出问题
DRI驱动也是新的
>>连着数据采集卡和马达之类的
这种系统要DRI作甚?
确实有很多人为了稳定,兼容而用 rh9 , 但不是拿 rh9 玩的, 不会乱装软件.
如果你要在 rh9 上跑以前的应用, 就不要玩它, 不装 dri .
如果你要玩, 就换个 fedora . 因为我的系统的某个任务要绘制出反馈信号的波形，比如我今天早上试了一下，其实波形已经不断的获得了，但画的时候惨不忍睹，本来我转glxgears的时候，就才100多哎！一拉窗口，3个gears根本就不动了。
再加上，系统没事就去跑那几个实时任务，只在空闲的那一点时间来绘图，没有加速的时候，是这种情况：你强制来跑一下绘图任务才能得到波形，你不改变参数，基本看不到波形。
我已经基本放弃启动这个ATI Mach64的DRI功能了，我打算换一个显卡，
请大家推荐一个能在Red Hat9下，实现3D加速，安装方便的显卡系列。
Thanks! Geforce 2/4,非常容易搞，RH9下可以驱动 好，等我在Linux我来贴，DRM的手册也说过要重新编译内核的时候去掉DRI选项，我也试过。
其实主要是，那个手册写的乱七八糟的，就是那个DRI网站上的手册，1，2，3。。。8步骤，不知道是全部做呢还是按自己的需求做，乱，我就稀里糊涂的全作了，然后挂上mach64.o，也没加速。
我还是找Nv的老显卡算了，听说他加的driver installer很好。 打算换一个Geforece 2-4 generic的老卡，是不是之后去他家下一个IA32的驱动程序，然后换了卡后在命令行下，运行这个驱动程序，然后跟着提示走就可以了？
Thanks.

Thank you! Great idea. will do as you suggested 大部分情况下，卡一换就重启，只是x进不去而已，不必担心。
配置一下，不是很难的事情。
相信GF2／4是很好找的东西，哪怕是GF2MX200，gear的成绩都上千的
