这个问题如何解决：Xlib: extension "GLX" missing on display ":0.0".

[lijie]

我是用emerge安装的ati-drivers-8.26.18，显示正常，就是某些程序打开会有这样的提示：

localhost lijie # glxgears
Xlib: extension "GLX" missing on display ":0.0".
Error: couldn't get an RGB, Double-buffered visual
localhost lijie # fglrxinfo
Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "GLX" missing on display ":0.0".
Error: couldn't find RGB GLX visual!

有一些游戏如quake、x-moto，还有googleearth等都会有这个提示并且不能运行 。

网上搜了一通，结果是很多，好像都不一样，而且大部分是N卡的，我的是A卡。

xorg.conf文件附后，是从SuSE里拷过来改的：

以前一直没注释的，刚才上网搜了一阵子，有人说要注释掉。不过这行注释了和没注释好像没什么差别。

最后面有这一段啊，是要注释掉？

[phus]

是把0660改为0666
另外load "dri"不要注释掉.

[Zhang Le]

一定不能注释掉
否则就没有direct rendering了

什么意思？我没听明白.
Load "dri"是驱动， 打游戏要用到
我的意思是不要注释掉它并且把dri的权限设为0666
