ubuntu禁止滑鼠喚醒睡眠中的電腦

動力來自電力供應不足...好啦其實就是我以前過得太奢侈了都在浪費電orz

點進來之前，我用的其實是lubuntu分支，並且禁止的是所有usb喚醒（參考資料有禁用單一裝置的方法）。符合需求請往下看



這個acpi，我記得還在用windows時，有些電腦用了睡眠一定要按電源鍵才能恢復，有些可以按鍵盤上的特定按鈕恢復，有些鍵盤隨便按就會恢復，有些碰到滑鼠就恢復...

當然此一時彼一時，現在知道這些可以從主機板bios控制，也能從作業系統列黑白名單來控制，這樣就不怕被沒給選項的bios綁住手腳←目前狀態
當然要細到一定要按鍵盤上指定按鍵才能喚醒這種，應該還是bios有多做事啦...就先不討論

感謝噗友dd-han / 呆翰 / 天津風的資料分享，看著並按照這篇的資料做了實驗

之後，得到了這樣的清單

阿那個device是在寫啥，根本有字天書，更慘的是我猜謎技能不包含英語，根本猜不出那個縮寫是啥...
...沒關係我們有lspci！

看著wakeup清單的sysfs node去找，把前面pci:0000:省略掉只對著後面看，就能找到「人類名稱」

這樣，我就能找到目前允許喚醒睡美人(:P)的有三個來源，一個是通過網路喚醒，第二第三都是通過usb喚醒...使用usb鍵盤滑鼠的話，走的就是這條
不過這裡有兩件事情比較奇妙：
參考的文章有提到他有power button，我這邊顯然沒有
我目前還沒搞定「睡進硬碟」的S4狀態（Suspend to disk），只做到睡進記憶體的S3（Suspend to ram），可是這張wakeup列表全都標記為S4喚醒...或者我理解錯了，或許寫S4不是說這行只在S4有效，而是這行會包含S1到S4都有效？
總之，我要禁止喚醒的滑鼠是在usb上，所以我決定把主機板上的usb給關了就好...因為我暫時看不出來怎麼關掉單一個usb裝置（後來發現下面回文有xd），更慘的是lsusb下去，我看鍵盤滑鼠好像被kvm合成一體了！？

嗯沒關係，我可以接受只能用電源鍵喚醒，所以鍵盤就請他犧牲一下了
下指令

ECHO EHC1 >/proc/acpi/wakeup
bash: /proc/acpi/wakeup: 拒絕不符權限的操作

...咦？也對，他不在我家裡

sudo ECHO EHC1 >/proc/acpi/wakeup
bash: /proc/acpi/wakeup: 拒絕不符權限的操作

還不行？剛才好像有看到有人提到要sudo再su

sudo su ECHO EHC1 >/proc/acpi/wakeup
bash: /proc/acpi/wakeup: 拒絕不符權限的操作

...拿的方法不對，抄另外一行

sudo sh -c "ECHO EHC1 >/proc/acpi/wakeup"

喔喔問我密碼了（敲

sh: 1: ECHO: not found

囧
...大小寫？

sudo sh -c "echo EHC1 >/proc/acpi/wakeup"

賓果！
再看一下wakeup確定EHC1被關了...確實disabled了！
至於寫進開機批次，讓它每次都自動除能嘛...
目前先測試而已，這種搞砸了重開就恢復的還滿方便的，確定沒後遺症再來寫

發文前測試了一下，我鍵盤滑鼠剛好就歸EHC1管，所以一猜就中xd，之後就是用一段時間確定沒問題，再寫進開機批次

其實是發給自己看的，尤其我已經忘記我當初怎麼改擷圖的儲存路徑以後xd


補充：噗友acelan提出另一種指令風格，把 sudo sh -c "echo EHC1 >/proc/acpi/wakeup" 寫成 echo EHC1 | sudo tee /proc/acpi/wakeup 。還沒理解指令原理，總之先記下來...
