Suspend
筆記型電腦在掛起後立即喚醒
我的筆記型電腦在掛起後立即喚醒（或者掛起失敗？它們是兩種不同的情況嗎？）。它是舊的東芝 Satellite C855D-S5105，8Gb RAM。它有一個最近安裝的 bodhi Linux（一個 Ubuntu 衍生產品，所以在很多事情上它的工作方式與 Ubuntu 相同）。我找到的解決方案都不起作用。BIOS 中的兩個候選項被禁用（Wake on LAN和Wake on Keyboard）。還有一個觸摸板，沒有滑鼠或藍牙接收器。下面我發布相關資訊，並附有來源。
$ uname -a Linux Orion 5.4.0-107-generic #121-Ubuntu SMP Thu Mar 24 16:04:27 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux試圖辨識喚醒的候選者（假設它掛起並喚醒）。
這裡似乎有一些啟用喚醒的設備（請參閱this）。

我設法通過以下方式避免喚醒。我整理了一個包含以下內容的腳本（受此
disable_devices_from_wakeup.sh啟發）#!/bin/bash declare -a devices=(EHC1 EHC3 OHC1 OHC3) for device in "${devices[@]}" ; do sudo sh -c "echo $device > /proc/acpi/wakeup" done將其設置為執行檔，然後執行它。現在我將所有 4 台設備都設置為
disabled，並且筆記型電腦只能通過蓋子或電源按鈕喚醒。因此，在不確切知道負責喚醒的設備的情況下，問題就消失了。在進一步的測試中，僅 4 個設備中的任何一個
enabled都足以防止掛起。這對我來說看起來很奇怪，但我沒有花時間分別理解每一個。全部：
- 使更改永久化。這是相關的問題。
