我無法讓“optirun intel-virtual-output”在我的 udev 腳本中工作

Question

我有一個 Thunderbolt 3 塢站，我想在插入和拔出後自動執行腳本。我能夠完美地運行我的“插件”腳本，但我的“插件”腳本不起作用。我已經手動測試過，一切似乎都正常工作。但讓 udev 運作似乎效果不太好。我無法找到 udev 引發的任何錯誤。任何幫助都有效。

/etc/udev/rules.d/81-thinkpad-dock.rules

SUBSYSTEM=="input", ACTION=="add|remove", ENV{ID_VENDOR_ID}=="17ef", ENV{ID_MODEL_ID}=="3083", TAGS=="power-switch", RUN+="/etc/sbin/thinkpad-dock.sh"

/etc/sbin/thinkpad-dock.sh

#!/bin/sh -e

sleep 1

if [[ "$ACTION" == "add" ]]; then
  DOCKED=1
  logger -t DOCKING "Detected condition: docked"
elif [[ "$ACTION" == "remove" ]]; then
  DOCKED=0
  logger -t DOCKING "Detected condition: un-docked"
else
  logger -t DOCKING "Detected condition: unknown"
  echo Please set env var \$ACTION to 'add' or 'remove'
  exit 1

function switch_to_local {
  export DISPLAY=$1
  VIRTUAL_OUTPUT_PID=$(ps aux | grep -i "intel-virtual-output" | awk 'NR==1{print $2}')
