暂停后在Xorg环境中恢复键盘设置

Question

我没有使用像Gnome或KDE这样的大型桌面环境，并且使用xset命令来更改键盘速率：

xset r rate 250 70

但是在系统挂起（通过 pm-suspend）后，这些设置会丢失，因为udev会删除并重新添加所有设备。

1. I tried to use udev rules:

   # /etc/udev/rules.d/00-custom-keyboard.rules
   ACTION=="add", SUBSYSTEM=="usb", RUN+="/usr/bin/xset r rate 250 70" # Not working
   ACTION=="add", SUBSYSTEM=="usb", RUN+="touch /tmp/test"             # Working pretty!
   

   I think the first rule is not working because xset utility requires some context data which is not available in the evdev context.

2. I tried to use xorg config, but found only the option to change the keyboard layout, namely XkbLayout and XkbOptions

有没有自动恢复键盘设置的方法，可以在系统暂停后自动进行恢复？

问题通过添加自定义脚本/etc/pm/sleep.d/00-keyboard得到解决，该脚本会在系统恢复时执行（不仅如此）。

#!/bin/bash
case $1 in
  hibernate)
    # Going to suspend to disk
    ;;
  suspend)
    # Going to suspend to RAM
    ;;
  thaw)
    # Resuming after hibernating
    ;;
  resume)
    # Resuming after suspending
    echo "Restoring keyboard settings..."
    /opt/scripts/keyboard.sh
    ;;
  *)
    echo "Something went wrong"
    ;;
esac
