问题：如何关闭一台显示器而不冻结另一台显示器？
我的规格如下。我有两个显示器。我想关闭左显示器，但是当我跑步时：
xrandr --output DVI-0 --off
我的左侧显示器变暗（理应如此），右侧显示器上的所有内容都冻结，我无法单击任何内容（我只能按 CTRL+ALT+F2 并重新启动）。我可以在第二台显示器上移动鼠标光标，但肉桂似乎完全冻结了。
我还尝试使用 cinnamon 的显示窗口关闭左显示器，但最初的结果是相同的（肉桂冻结），30 秒后，当 cinnamon 尝试恢复设置时，显示器闪烁，实际上没有恢复任何内容。
它之前还在运行，但不确定什么时候停止了（可能是在 Mint 更新之后）。
知道如何解决吗？预先感谢您提供任何提示。
