如何完全抑制蓋子開關事件？
語境：
由於我的 2 合 1 敞篷車缺少驅動程序，將螢幕向後折疊只會觸發蓋子開關事件。這會導致筆記型電腦掛起，或者當在 Gnome 中禁用“關閉筆記型電腦蓋時掛起”時，仍然會導致所有輸入設備被禁用（包括觸摸屏，這會使平板電腦模式無用）。
作為一種解決方法，我想手動處理切換到平板電腦模式。這需要禁止所有蓋子開關事件。
問題：
如何在 Linux 中完全禁止蓋子開關事件？
或者，找到一種方法來列出/禁用響應蓋子開關的程序將解決該問題。
目前，在平板模式下折疊螢幕並返回會記錄以下事件：
Jul 25 23:58:54 jl-xps systemd-logind[816]: Lid closed. Jul 25 23:58:58 jl-xps systemd-logind[816]: Lid opened.蓋子開關事件映射到
/dev/input/event0./proc/bus/input/devices列表（截斷）：I: Bus=0019 Vendor=0000 Product=0005 Version=0000 N: Name="Lid Switch" P: Phys=PNP0C0D/button/input0 S: Sysfs=/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0C0D:00/input/input0 U: Uniq= H: Handlers=event0 B: PROP=0 B: EV=21 B: SW=1嘗試：
方法1：，
systemd-inhibit取自關閉筆記型電腦蓋時如何禁用自動掛起？# systemd-inhibit --what=handle-lid-switch sleep 1m然後在定時器結束前翻轉螢幕。蓋子開關事件仍然由 記錄
systemd-logind，我可以看到/dev/input/event0正在寫入（並且其他輸入設備仍然被禁用）。方法 2：ACPI
$ echo "LID0" | sudo tee /proc/acpi/wakeup並檢查它是否確實被禁用：
LID0 S3 *disabled platform:PNP0C0D:00使用相同的
systemd-logind日誌並且/dev/input/event0仍然被寫入。方法3：蠻力
# mv /dev/input/event0 /dev/input/event0-off # ln -s /dev/null /dev/input/event0蓋子開關事件仍由 記錄
systemd-logind。因此，這似乎/dev/input/event0只是提供資訊。系統資訊：

您可以測試取消綁定父設備上的驅動程序。這將刪除子設備以及存在的任何其他子
input0設備。cd /sys/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0C0D:00 echo PNP0C0D:00 | sudo tee driver/unbind第二個範例，基於您提到的其他輸入設備：
cd /sys/devices/pci0000:00/0000:00:1f.0/PNP0C09:00/INT33D6:00 echo INT33D6:00 | sudo tee driver/unbind（如果您安排自動執行這樣的命令，您將需要確保它在綁定驅動程序後執行……在許多情況下，我認為您可以將其放入其中
rc.local）。進一步閱讀
