从KDE等离子5锁屏挂起linux

Question

如何从KDE LockScreen中挂起？

我使用的是KDE的默认锁定屏幕，您可以在某种程度上配置它

但是我还没有找到办法把我的电脑挂在锁屏上，所以我不得不输入我的密码，然后每次我需要的时候都挂起它，这是非常不方便的。

目前，我修改了KDE等离子锁屏文件(特别是LockScreenUi.qml)，以添加挂起按钮。但也许这是一种更简单的方法？

也是的，我看到了reddit邮报和一些没有任何解决方案的kde论坛上的帖子。

我的配置：

uname -a
Linux neko 4.15.14-1-ARCH #1 SMP PREEMPT Wed Mar 28 17:34:29 UTC 2018 x86_64 GNU/Linux

kded5 --version
kded5 5.45.0

plasmashell --version
plasmashell 5.12.5

补丁本身，它基本上添加了带有默认图标的挂起按钮，并使用PowerDevil KDE服务进行挂起(找到了这个使用注销文件)。

冒着自己的风险使用：

KDE程序跟踪器上的特性已经有了一个报告(谢谢莱肯斯廷提供的链接)

谢谢你的贴片，它很有魅力！

与处理物理电源键相同：

      Keys.onPressed: {
+            if (event.key == 16777399) performOperation("suspendToRam")

确认在kded5 5.67.0和plasmashell 5.17.5 (Gentoo)上工作。

Answer 2

非常感谢!效果很好。

我的笔记本电脑也有一个睡眠键，所以我又增加了一行：

      Keys.onPressed: {
+            if (event.key == 16908292) performOperation("suspendToRam")
            uiVisible = true;
            event.accepted = false;
