ubuntu11.10 osg3.0 测试demo出错

woshishui

下载osg3.0，编译通过。
下载了data包后，运行示例。
osgviewer OpenSceneGraph-Data-3.0.0/cow.osg
Got an X11ErrorHandling call display=0x1b67bb0 event=0x7fff7145a6e0

这是不是显卡驱动引起的？ 我没专门安装显卡驱动，是默认安装的ubuntu系统。

经确认，机器显卡是AMD的ATI HD6770。
安装显卡的3D加速后，问题仍然存在。

cmake过程中没有什么值得注意的，至于您的运行结果。第二个example.osg是因为您用了比较旧的文件格式，因此不再识别了。第一个cow.osg的问题我不太清楚，用不带纹理的cessna.osg是否也有一样的问题？

多谢array的关注。

刚才做了一个更简单的测试，发现工作环境连logo都不能正常显示。
osglogo

至于你建议的测试用例，结果如下：
osgviewer OpenSceneGraph-Data-3.0.0/cessna.osg
Got an X11ErrorHandling call display=0x2149450 event=0x7fffb0fded90

现在真是迷惑极了。

请问array, 这个网页上的问题及Robert的回答，跟我碰到的问题是不是同一类？刚接触osg，迷惑。

I made it.
要正常安装驱动才行。确认驱动是否正常安装，可用fglrx命令。

你好！我也遇到这个问题，我的是读字体的时候。请问你安装了什么驱动？
