当我将台式电脑置于睡眠状态时，当我恢复时，我的键盘（Aukey KM-G9）不起作用。如果我拔下电源然后再插上，它就可以正常工作。我目前正在使用 Ubuntu Gnome 17.04，但 16.04 也遇到了同样的问题。
编辑：我试过我的旧键盘，它在挂起后确实可以工作。我不知道为什么我的新键盘会出现这个奇怪的问题。新键盘是机械键盘。
输出如下lsusb：

答案1
我设法通过在启动选项中添加一个简单的字符串来解决了这个问题。
首先，打开终端并输入
lsusb
此命令将显示 USB 设备。它名为 Aukey KM-G9盛群半导体股份有限公司写下ID，在我的情况下是 04d9:a0cd，它被冒号 (:) 分成两部分
然后，在终端上输入：
sudo gedit /etc/default/grub
这里我们有 grub 的配置，要小心。
使用这种字符串更改 GRUB_CMDLINE_LINUX_DEFAULT：
usbhid.quirks=0x*ID_before_colon*:0x*ID_after_colon*:0x00000008
保存文件，然后在终端中：
sudo update-grub
重新启动计算机
这应该可以解决这个奇怪的情况。我认为这与键盘与 Linux 内核的兼容性有关。
