    Deepin 20，Thinkpad x1 2021，拔掉外接HDMI外接显示器后屏幕只显示上面一条，下部黑屏，但是鼠标可以整屏幕移动。下面跟帖是拍到的照片。

    接上外接显示器（即使外接显示器断电）后屏幕变正常，断开外接显示器，笔记本电脑屏幕又变成只显示上面一条。

    重新启动后还是这样。

    现在只能接上外接显示器使用。ctrl+alt+f2可以正常打开终端。

    请高手指教，应该更改哪个配置文件

    下面是xrandr的输出，第一个是没有外接显示器时的输出，第二个是有外接显示器时的输出。

     

    没有外接显示器时，Screen 0 是 1920 x 2280，而eDP-1 connected primary 1920x1200+0+1080

    应该是1920 x 2280的2280错了，应该改成1200。

     

    哪位知道如何修改，请指教

    已经升级至最新版本了，问题依旧：拔掉外接显示器又黑屏，100%复现。笔记本当台式机用？？？

    拔掉外接显示器，笔记本黑屏，可以进console。接上外接显示器，恢复正常。
