第三台监视器不可见，显示“X”光标-双GeForce GT 1030和三台Benq显示器Nvidia
提问于 2020-03-21 18:21:57
所以我买了2张GeForce GT 1030卡，想同时在上面运行3台监视器。2在第一显卡上分别通过HDMI和DVI连接。这是唯一出现在xrandr.Additionally输出中的两个，只有第一个显卡上的2个监视器在屏幕上显示为ubuntu。
事实上，这两个显卡是相同的模式和两个屏幕是相同的模式，可能没有帮助。

640x480 75.00 59.94 59.93Nvidia-设置可以看到它们，但是不可能将它们放在看起来相同的xscreen上。或者使用xinerama。
这个问题有点类似于这个- 显示“X”光标的第三个监视器，但是我不能让X光标显示在第三个屏幕上，它保持绿色，但没有输入。
还附上了我的xorg.conf，由nvidia-设置生成。

为什么不尝试基本的故障排除方法--将第三个屏幕更改为正在工作的HDMI/DVI端口。电源循环电视和CPU (拔出他们的电缆，按住电源按钮1分钟，然后把它插入)。
此外，在使用2 GPU的同时也会出现问题，我强烈建议您要么使用CPU的集成图形，要么使用一张卡进行测试/实验。
