我不知道是什么引发了这种情况，但重启几次后，一些键盘快捷键不起作用。
例如，我通常使用 guake 打开它F12，但现在它不起作用了。但是，Ctrl+Alt+T它工作正常。我可以使用键盘快捷键复制和粘贴文本，没有任何问题。另一个不起作用的是我Ctrl+Shift+V分配给打开 CopyQ 剪贴板菜单的快捷键。
我可以从设置中定义自定义键盘快捷键来打开和关闭 guake，但它的操作与以前不同。通常它会在我的鼠标处于活动状态时打开终端，但如果我使用命令将其定义为自定义快捷方式，它将始终在主显示屏上打开。
所以我认为，以某种方式固定在 gnome 上运行的应用程序无法将它们自己的键盘快捷键注册到 gnome。
当我查看 gnome 日志并过滤 copyq 时，显示以下日志：

以下是 guake 的结果：

我遇到了同样的问题。我发现唯一能解决这个问题的方法就是：从设置中设置自定义快捷方式。 屏幕截图
ubuntu Xorg好的，我通过在登录前单击右下角的设置按钮切换到登录屏幕来使其工作。copyq 和 guake 都按预期工作。
