我最近在一台带有 cinnamon 桌面环境的新笔记本电脑（带触摸屏的 Dell XPS 13）上安装了 Debian Stretch（测试）。对于我使用的英特尔显卡xserver-xorg-video-intel。当我登录时，屏幕会在几秒钟后（大多数情况下）关闭（没有背光，没有像素）。我意识到这可能是 systemd 和 cinnamon 接收“盖子打开/关闭”事件的问题，所以我修改/etc/systemd/logind.conf如下：

这样，只有肉桂负责盖子事件。尽管如此，我的屏幕还是时不时地关闭（这似乎与登录没有任何关系，尽管我必须合上盖子才能“重新启动”屏幕）。看起来没有什么问题Xorg.conf，但我可能是错的。这是 Xorg.log：
