r300以上只有2D加速
wiki上的硬件列表样有提到
man radeon里也有

r300的驱动太封闭了：（目前想在开源驱动跑3D硬件加速显然不现实。只是glxinfo能够得到direct rendering: Yes以及1500左右的FPS也该满足了。

ifree

原来：Radeon X600, M24 (2d only)
是只有2D加速Only，先没有搞懂2d什么意思。

算了，退回gcc 3.4 gentoo-sources-2.6.15 用ati-drivers算了。好歹也有个2600左右的FPS。

我的ATI 9200 用 ATI 的开源驱动运行 glxgears 的分数比官方驱动高出了 300 多分，还不错。

刚才用XGL LiveCD启动，发现在上面用glxgears有4500多；比我自己用官方驱动多了2000！！
它好像也是用的官方驱动啊？难道装了xgl后对3D性能也有提高吗？

zlbruce

恩，我开启 Xgl 后跑的分数也是要高很多的。

我先前在xgl里用xf86-video-ati-6.5.7.4也能得到4xxx的分数，不解。

cluck

resolved!
add -Wl,-z,nonow to your LDFLAGS int /etc/make.conf,
then reemerge xorg-server

2. LDFLAGS="-Wl,-O1 -Wl,-z,nonow -Wl,--enable-new-dtags -Wl,--sort-common -s"

请问下面的问题该如何解决？最近升级xorg-server 和 ati-drivers之后就一直这样
我用的是ATI的显卡，xorg 7.0

我先前在xgl里用xf86-video-ati-6.5.7.4也能得到4xxx的分数，不解。

xf86-video-ati能支持到哪个档次的显卡的3D渲染？

midx

想当然的话，大概就是radeon 8500了

zhllg

man radeon就看到了
我的是radeon mobility 9200
3D没有问题
