我是 xubuntu 的新手（因为我的笔记本电脑无法运行任何现代的 Linux 版本）。[pentium m] 我的键盘会随机挂断 - 没有任何警告。（当我这样说的时候，有几次菜单也不起作用）鼠标仍然可以工作，如果我切换到另一个 tty，键盘可以正常工作。从这里我可以运行 init 6 来重新启动系统，一切又恢复正常了。
我注意到当我使用笔记本电脑上的键盘快捷键时更容易发生这种情况，例如 fn+vol up 或 fn+vol down。
我没有安装专有的 ati 驱动程序，也没有更改键映射。更新或未更新，它都会发生同样的事情。（我现在已经安装了 12 次）

答案1
不久前，我在类似的 Centrino M 笔记本电脑上遇到了一些问题：
- 使用 fn 键调暗 LCD 面板时，屏幕完全变黑
- 使用 fn 键查询电池电量时完全锁定。
在我看来，这些功能是硬连线到 BIOS 中的，并且只在 Windows 上测试过。当时的解决方法是在内核命令行中附加 NOAPIC NOLAPIC，ymmv。
