我有一台联想 510p 笔记本电脑，集成 Intel HD 4600 显卡，外加 2 个 GeForce GT 755M-s，其中一个位于超级托架中，因此是可拆卸的。我运行的是 Lubuntu 13.10。我使用专有的 nvidia 驱动程序 (331)。
我安装了大黄蜂，当没有可移动显卡时它似乎工作正常，但是如果我插入超级托架，就会发生奇怪的事情。
不知何故，似乎集成的英特尔卡没有被拾取，我不知道实际上发生了什么。
一些日志：

所以最大的问题是：这是正常的吗？我以前从来没有用过这样的机器（也从来没有用过大黄蜂），所以我真的不知道会发生什么。
尽管如此，这种情况似乎很奇怪，如果可能的话，我想在两种情况下都使用英特尔卡，而且当我想要一个正常运行的 Linux 时，不必移除第二个 VGA 就更好了。 有没有办法例如完全禁用/隐藏 optibay VGA？无论如何我都不想在 Linux 中使用它。
