我正试图通过将我的旧笔记本电脑变成媒体播放器来赋予它新的生命。这是一台较旧的 HP DV7，我运行的是 Lubuntu 17.04。
lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 17.04
Release: 17.04
Codename: zesty
我尝试过让 HDMI 工作但没有成功。我已经用另一台笔记本电脑测试了电视，HDMI 工作正常。这台笔记本电脑还可以通过 HDMI 输出到 24 英寸显示器，没有问题。当我将笔记本电脑插入笔记本电脑时，液晶屏分辨率也在可视区域之外，我不知道在哪里更改分辨率。这是 xrandr - - 笔记本电脑插入时的电流。

我似乎也不知道如何使屏幕成为外部/镜像/等。常规的 fn+f4 似乎不起作用。
