我最近尝试了xorg-edgersppaNvidia-352驱动程序，但它搞砸了，所以我删除了它。现在，我无法make安装以前可以安装的东西。我正尝试将示例2_graphics/Mandelbrot作为CUDA6.5 示例的一部分。我知道这一点应该Nvidia-331它可以工作，因为当我刚使用来自的包安装时它就工作了Ubuntu。
当我尝试时make，我得到：
>>> WARNING - gl.h not found, refer to CUDA Samples release notes for how to find and install them. <<<
>>> WARNING - glu.h not found, refer to CUDA Samples release notes for how to find and install them. <<<
一个简单的谷歌搜索就让我意识到我可能需要apt-get install libglu1-mesa-dev，但是当我这样做时，我得到了以下信息：
Reading package lists... Done

当我尝试安装这些软件包时，每个软件包都会告诉我类似“这些是虚拟软件包，请按名称指定一个”或相同的E: Unable to correct problems, you have held broken packages.
这是 ppa 遗留的问题吗xorg-edgers？如果是，我该如何解决它？
