libGL.so这个文件去哪里找哦？显卡驱动应该没有问题，因为显示器刷新率正常的，但是不能用beryl

我的显卡是集成的x1250

你没安装显卡驱动？或者opengl支持的没开。搜索render

eexpress 写了：你没安装显卡驱动？或者opengl支持的没开。搜索render

安装了显卡驱动的,是源里面的驱动，但是不能实现桌面效果，因为刷新率正常我也就没有管它（估计是我这款x1250不支持）

这个是fglrxinfo的结果
Xlib: extension "XFree86-DRI" missing on display ":0.0".
display: :0.0 screen: 0
OpenGL vendor string: Mesa project: www.mesa3d.org
OpenGL renderer string: Mesa GLX Indirect
OpenGL version string: 1.4 (1.5 Mesa 6.5.2)

搞不懂为什么我明明装的ati的驱动，怎么会显示上面的东东.....

这个是搜索render的结果

Mesa是缺省的驱动，就是没正确配置好驱动哦。
搜索render是这个意思：是搜索论坛的render关键词。
$● glxinfo |grep render
direct rendering: Yes
OpenGL renderer string: GeForce Go 7300/PCI/SSE2
GL_NVX_conditional_render, GL_SGIS_generate_mipmap, GL_SGIS_texture_lod,
那Yes就表示了直接渲染正常的意思，就是图形加速开了。

自己手动做一个符号链接
cd /usr/lib
ls -l | grep GL

sudo ln -s libGL.so.1.2 libGL.so
sudo ln -s libGLU.so.1.3.060401 libGLU.so
