第二个GPU的所有监视器都断开连接。 Ubuntu 18.04 – Nvidia 396.54

我正在建立一个带有2个GPU(Nvidia GTX1050 Ti)和6个显示器( 三星md230x6 )的工作站 。

除了桌面仅显示在第一个GPU的显示器上之外,它一切正常。 其他三个是黑色的:我无法移动任何窗口,但鼠标光标实际上显示为带有白色轮廓的黑色十字。

有趣的是,我可以通过nvidia-settigs GUI Color Correction实际改变黑屏的颜色。

看起来与显示“X”光标的第3个监视器中的问题相同。

更新:

事实certificate,使用专有驱动程序和两张卡将桌面扩展到6台显示器是不可能的。 感谢Generix的答案 。
