mesa,libgl-dri,libgl都安装了吗，没的话pacman安装，再重新X -configure一下

都装了，都是最新的了

把Depth换成24试试

2. Section "Screen"
3. Identifier "Screen0"
4. Device "Card0"
5. Monitor "Monitor0"
6. DefaultDepth [color=red]24[/color]
7. SubSection "Display"
8. Viewport 0 0
9. Depth [color=red]24[/color]
10. Modes "1024x768" "800x600"
11. EndSubSection
12. EndSection

复制代码

难免有错

7.0.1的mesa有bug,arch一直没更新到7.0.2,不知道怎么回事。

用了24，FPS降到200多

把7.0.2的3个包下了下来，但是没有PKGBUILD

可以把7.0.1的PKGBUILD改改来用。

那个warning是因为你打开了aiglx。关闭aiglx那个glxgears会有点提升。不过这个跟驱动有关系。3d显示打开，那么就这样了。glxgears只是opengl性能而已。不能作为评价显卡好坏标志，只能显示3d是否打开

Section "ServerLayout"
...
option "AIGLX" "0"
...
EndSection

24是色深。一般使用24。不然看图会过渡非常不均匀

type1可以注释掉。也就是不要这个

是不是集显的opengl性能都不好？
