无多个X-屏幕与AMD FirePro W600

Question

我正试图建立一个系统与9个连接的显示器使用两个AMD FirePro W600卡，在这里我需要配置每个显示器作为单独的X屏幕。到目前为止，我设法使两辆车都能工作，即每个连接的监视器(测试用的4台)正确显示桌面，我可以使用显示设置对齐它们的空间。

然而，我未能配置多个X屏幕.我用Ubuntu的变体(18.04和18.10)进行了测试，使用了Linux安装中包含的驱动程序，并尝试了来自PPA (ppa:oibaf/图形-驱动程序)和官方AMD驱动程序(amdgpu-pro-18.20和amdgpu-pro-18.30)的驱动程序。

我开始用XOrgConfCreator创建Xorg配置，但也尝试了我用Xorg -配置创建的变体。

第一个PsychToolbox变体导致登录时屏幕闪烁，我无法再登录。我发现radeon驱动程序仍然被加载，因此禁用了它(基本上遵循步骤在此描述)。这样，我就可以登录，所有连接的屏幕都是活动的。但是，X屏幕配置被忽略了，这意味着我没有单独的屏幕。但是，xorg.conf文件是加载的，当我把这个文件搞砸时，我的屏幕上有一个黑色的日志。但是，设备部分中的屏幕分配没有任何效果。我修改了xorg.conf文件，但是无论我尝试了什么，我要么有一个黑登录，要么没有效果。

我没有发现任何明确的信息，在网上说，我所有的尝试使用这张卡是在静脉。但我的想法和大约5个关于AMD和尝试我的运气与Nvidia配置(最多8屏幕)。也许这里的任何人都有一些解决AMD卡问题的建议。

我附加了PsychToolbox Xorg配置文件，附加了日志文件，以及几个查询系统信息的调用的输出。

谢谢你的建议，

沃尔夫
