我使用 nvidia 二进制驱动程序，因此需要 /usr/lib 中的 libGL* 链接指向 /usr/lib/nvidia-current。但每当我安装一些 opengl 相关软件包时，Ubuntu 都会坚持将 libGL.so.1（而不是 libGL.so）指向 libGL.mesa.so。
到目前为止，我总是覆盖错误的链接，对此我并不介意。我真的很想知道如何修复此行为，或者我应该在哪里寻找导致此问题的可能原因。
编辑：也许我应该补充一点，我使用了来自 ubuntu-x-swat ppa 的 nvidia-current：
/u/lib> apt-cache policy nvidia-current
nvidia-current:
Installed: 275.09.07-0ubuntu1~lucid~xup1
Candidate: 275.09.07-0ubuntu1~lucid~xup1
Version table:

我需要这些，因为我的 GTX 460 不受官方 lucid 存储库中的驱动程序支持。

当一切正常工作时，这是 /usr/lib/libGL 符号链接的布局：

例如，当我删除并安装 libglfw2 时，只有 libGL.so.1 链接更改为指向 libGL.mesa.so：

我正在回答这个问题，如果您还有任何问题，请发表评论，我会删除它。
删除这些符号链接：
/usr/lib/libGL.mesa.so
/usr/lib/libGL.so
/usr/lib/libGL.so.1
据我所知，这些链接不应该默认存在，“替代系统”应该负责处理使用哪些 libGL 文件。
