我对 Linux 还很陌生,但我已经安装了 Ubuntu 16.04LTS,它运行顺畅。但我希望能够通过从电脑到电视室的长 HDMI 电缆将双屏(甚至单屏)连接到电视上。在 OS X 下运行良好。
我的主屏幕通过 DVI 连接。然后我的电视通过内置英特尔显卡上唯一的 HDMI 连接。
当我关闭电视时,屏幕显示会将电视显示在我正常屏幕的右侧。而 xrandr 显示 HDMI-2。当我打开电视时,电视从“屏幕显示”中消失,并且 xrandr 显示 HDMI-2 已断开连接。
我尝试使用“Linux 版英特尔图形工具”,甚至尝试使用其他地方建议的 Nvidia 驱动程序。但无济于事。

有人能给我一些建议吗?我不太擅长这些,但到目前为止我还是摸索着熬过来的。非常感谢你读到这里,谢谢,汤姆
