我在 MacBook Pro ( ) 和两台 27 英寸 Apple Thunderbolt 显示器上运行了 16.04(带内核) MacBookPro12,1
。MacBook 有两个雷电端口。15.10 也出现了同样的问题,所以我决定尝试更新的内核,因此转到了 16.04 dev。
如果我插入一台显示器,它就会被识别,我可以将其用作显示器。在单台显示器的情况下,无论我使用两台显示器中的哪一台或两个端口中的哪一台,所有组合都可以工作。如果我插入两台显示器(菊花链连接或将每台显示器插入单独的雷电端口),两台显示器都会显示出来,lsusb
但只有其中一台可以配置为显示器。

其他有趣的事实:两个显示器上的 USB 集线器在菊花链连接或单独插入时都可以工作,即使在未被识别为显示器的显示器上也是如此。
有没有办法让两个显示器都工作?
