如何判断显卡启动了3D加速？

这一行，yes或者no都可以有3d加速！


OpenGL renderer string: Mesa GLX Indirect
这一行，显示Mesa GLX Indirect （就是软的3d驱动），
必须要显示对应的显卡才是3d的硬加速！（也就是真正的3d驱动）


再次强调
glxgeras
只是一个参考分数！
我的915开不开3d分数差别不大！但是确实有一点提升！[/quote]
那我的应该就是有开起3D硬件加速吧？？我的是NV的卡

这个所谓的3D加速和OPENGL是什么关系？
谢谢

linux的3d加速就是硬件支持opengl！

我的显卡是ATI X1300,最近才在ML2.0下安装上驱动。我的经验是最好别在图形介面下安装驱动，我就为此走了很多弯路，在X图形桌面下，按置顶贴的方法安装后，虽然我的宽屏（19“）能上到1440×900了，但3D加速始终没开启。后来，一个偶然机会，我进入字符模式，尝试安装了显卡驱动，重启后，居然开启了3D加速。你要遇到这类问题，不妨试试。

那所谓的软件加速又是怎么回事呢？
能介绍篇关于这两者的区别的“通俗”的文章吗？

该死，昨天下线急，居然忘了贴这个，安你说的应该有开硬件3D吧

虽然
direct rendering: No

但是实际上楼上的应该是开了3d加速了！
OpenGL renderer string: GeForce4 MX 440 with AGP8X/AGP/SSE2


没有开3d的都是软3d加速，下面那行显示如下。
OpenGL renderer string: Mesa GLX Indirect


Mesa GLX Indirect
就是软加速。

PXE2

fuser /dev/nvidia0  就知道是否有加速了。
