没有官方驱动能用3D加速吗？

我的卡是ATI Mobility FireGL 7800，官方不提供驱动，可是没有3D加速怎么玩3D游戏啊？目前glxgears的值才185

从linux-laptop.net上找到了这段话：

The graphics chip in this laptop shows up as "VGA compatible controller: ATI Technologies Inc Radeon Mobility M7 LX [Radeon Mobility FireGL 7800]".

Automatic configuration of the graphiccard by sax2 did work without any problems. By the way, here is my XF86Config file. SuSE 8.1 comes with Xfree 4.2.0 and I use the "Radeon LX" driver for the display. By setting "DefaultColorDepth" to 16, 3D-accaleration is enabled. Acutally 24bbp- and 32bbp-acceleration are not supported by this drivers. I could run RtCW and Q3A for testing the quality of 3d-acceleration of this drivers. See the Performance section for the result. Xine runs on this system without any frame-drops with 1600x1200-fullscreen.
是不是说，颜色设成16位就支持3D加速了？

By setting "DefaultColorDepth" to 16, 3D-accaleration is enabled.
你得在xf86config文件里把 3d accaleration设置成enabled。不是光把颜色设成16位就完事。

你的配置倒是没啥问题，你在xf86config里有没有找到3D-ACCELERATION 这一项？

!@#$%^&*?+_$^%@@!^%&%#%&^$##
我没找到3D-ACCELERATION，在瞎改了一堆选项，从网上找了一堆资料，运行xconfig达n+999999次之后，我发现glxgears值不知为什么突然升到1300多了……

那我就恭喜你一下了

老大请问你是怎么改的,改了哪些地方,我也是ATI的卡,请分享下,多谢!

fantasy2 · 发表于 2005-7-20 21:29:55

到最后是什么都没改，xconfig自动配置的

都去装上fglrx驱动，一般就都解决了。
